760 LIVE STEAM SYSTEM

760 Live Steam System

The Stickle 760 Live Steam System is tailored for the maximum drainage of today’s high speed corrugators in an easy to understand and operate trapped steam system – f&t steam trap .. The 760 System utilizes modern steam trap technology to effectively remove condensate from the rotary joint and hot plates. See our Stickle 760 Live Steam System Brochure for more.

Guaranteed Drainage

All condensate returns from the singlefacer group and triple stack are returned to the Stickle High Pressure Condensate Receiver where condensate is returned to the boiler room as a controlled event. Differential pressure controls maintain a set difference in pressure between the steam pressure entering the machine and receiver vessel. This guarantees condensate drainage at all pressures and machine speeds.

The doublebacker is split into three controlled zones: each zone is fed live steam, trapped, and the condensate is returned to the Stickle Deaerator as low pressure return. The flash steam generated is then reused in the Deaerator to deaerate make up water.

Stickle knows boiler rooms, having manufactured Deaerators since 1907 and High Pressure Condensate Return Systems since 1934. Also, since the inception of the Mechanical Division in 2006, we handle all the process piping requirements with our own installation crews and project managers.

Many corrugators are equipped with systems which automatically control ballast systems in relation to machine speed. However, since these systems respond only to speed, they do not compensate for changes in roll stock moisture, temperature (cold weather months), and adhesive application: all of which affect heat transfer requirements.

Other systems therefore require frequent manual tuning, which, in the absence of dependable refer­ence points, are really guided only by observing the board coming out of the stacker. When such ob­servations suggest corrections should be made, over or under correcting occurs, resulting in additional sub-quality board.

The key to efficiently producing a consistent quality corrugated board is the ability to maintain desired web temperature levels independent of speed.

Stickle Steam has the proven solution: Stickle Thermocon Process Control

Thermocon constantly monitors the Double facer liner temperature coming off of the last hot plate. Thermocon compares the measured temperature to pre-set and predetermined values, and if required, automatically adjust ballast systems and hot plate steam pressure to attain the pre-set temperature.

Thermocon system is compatible with all corrugators and steam systems and is composed of a group of independent control centers, each of which is dedicated to the machine component it serves.

250 SERIES TRAY TYPE DEAERATORS

250 Tray Deaerators

The Stickle Deaerating Feedwater Heater evolved from our first Open Coil Feedwater Heater patented in 1901. The first generation of Stickle Feedwater Heaters were employed to capture calcium in boiler feedwater. It was later learned the feedwater eater served the more important role of oxygen and carbon dioxide removal. The extraction of these harmful gases is the primary function of all Stickle Deaerators. Removal of these non-condensable gases from make-up water for boiler feed, protects boiler, condensate return lines, piping and pumps from corrosive gases. See our 250 Series Tray Type Deaerators Brochure for more.

Stickle Series Deaerators

Stickle Deaerators are designed to completely remove oxygen and carbon dioxide to the accepted level of “zero”. “Zero” is defined by the indigo carmine test method as soluble oxygen is not to exceed .005 cc per litre and soluble carbon dioxide to be virtually zero.

  • Engineered for precise, dependable performance over wide load shifts
  • Custom-designed to user specifications…to meet your exact needs
  • Built to exceed ASME Code, Section VIII, Division I…for years of reliable operation
  • Backed by the industry’s ONLY 10-year non-prorated standard warranty

Two-stage deaeration, as provided by the Stickle 250 Series tray type deaerators, significantly reduces the expense of boiler room maintenance and repairs by minimizing the potential for corrosion to boilers, pumps and pipes. This is done by removing the highly corrosive, non-condensable oxygen and carbon dioxide from feedwater before it enters the boiler cycle. Proper deaeration extends the useful life of boiler systems by many times.

A Stickle 250 Series deaerator operates at a minimum of 5 psig and 227 degrees F. The deaerator is designed to maintain a dissolved oxygen level of no more than 0.005 cc/l, with a negligible level of carbon dioxide.

  1. Feedwater, containing non-condensable corrosion agents found in all water supplies, enters the vessel through pressure compensated, spring-loaded valves.
  2. Deflectors on each valve spread feedwater out into a thin, flat sheet of small droplets.
  3. Steam rises to surround the water droplets and heats them to a temperature relative to the pressure being maintained on the unit.
  4. Steam condenses and falls with feedwater onto a large cone, which carries the water to the tray section below the conical outlet.
  5. Heated feedwater is ready for agitation and scrubbing by steam.
  6. Feedwater cascades over a series of properly sized trays, all arranged in rows, one above the other and all lying on the same axis. Each row of trays is staggered so the feedwater always falls on the center of each of the trays in the next row.
  7. As feedwater moves downward through the rows of trays, the scrubbing of the rising steam removes non-condensable oxygen and carbon dioxide gases.
  8. These non-condensable gases are carried by the steam to the vent condenser, where the steam condenses and the gases are removed through a temperature-controlled orifice. Stickle engineered steam boiler piping.
  9. Deaerated feedwater flows into the boiler cycle, minimizing corrosion potential.

860 HYBRID CASCADE SYSTEM

860 hybrid cascade system

The Stickle 860 Hybrid System is the Stickle version of a cascade steam and condensation system. See our 860 Hybrid Cascade System Brochure for more.

A Hybrid cascade system provides the most efficient means of continuous removal of non-condensable gases for the corrugator. Also, we deliver 100% of the boiler steam pressure/temperature to every heated roll in the singlefacer group. This allows for better heat transfer and a hotter corrugator.

The Stickle 860 Hybrid System guarantees pressure differential across the machine at all times. This insures condensate drainage at running speeds and at idle. No cold spots … no blisters on start-up.

Stickle knows boiler rooms, having manufactured Deaerators since 1907 and introducing our High Pressure Condensate Return System in 1934. Also, since 2006 with our Mechanical Division, we handle all the process piping requirements with our own installation crews and project managers.

FLASH TANKS

Flash Tanks Stickle Steam

FLASH TANKS ENGINEERED BY STICKLE STEAM SPECIALTIES

In these times of exorbitant energy costs conservation of heat in every area of steam handling and usage is a prime concern. The flash tank is a powerful weapon in your fight for energy conservation. The flash tank serves a vital function. It provides for SAFE reduction of pressure and temperature of a water stream while containing all of the heat content of the water when used in a closed system. In fact, the flash tank is the component which allows a closed system design to be used. In a flash tank the pressure of the incoming water is reduced. A portion of the water instantly changes, or, “flashes” into steam. This steam may be reused to replace or supplement what otherwise would be live steam from the boiler. See our Flash Tanks Brochure for more.

For any plant or process which utilizes steam the flash tank is a necessity in safely and efficiently handling the resultant condensate as well as other water streams. Here are some of the common applications for which a flash tank has earned a reputation as safe, reliable, and economical:

  • Cascade condensate drainage systems
  • High pressure condensate return systems
  • Condensate heat recovery
  • Continuous boiler blowdown heat recovery
  • Reduced pressure steam generation
  • Steady state differential drainage
  • Intermittent boiler blowdown discharge

285 DEAERETURN

285 Deaereturn

Stickle has drawn from its extensive deaerator experience and knowledge to design a combination deaerating feedwater heater and high pressure receiver one that we have dubbed DeaeReturn. The word DeaeReturn is the combination of two words basic to the function of a deaerating feedwater heater deaeration and return. See our 285 Deaereturn Brochure for more.

The Function

The DeaeReturn is designed to handle the tasks of deaeration and proper heat transfer that is required for all feedwater. The DeaeReturn does all these things while also maintaining a constant pressure differential with the boiler. This allows for less boiler strain resulting in energy efficiency. The DeaeReturn eliminates the space requirements of typical boiler feedwater equipment by placing both tanks on one stand.

The Basic Operation

The feedwater is first pumped to the Deaerator where it is attacked by steam and agitated to remove all non-condensable gases. The feedwater moves to the high pressure receiver tank where it is heated. The pressure and temperature of the feedwater in the DeaeReturn Receiver is usually within 20-50 psi and 20-30 degrees F. of the actual pressure and temperature of water within the boiler drum itself. One important feature of the DeaeReturn Receiver is that should the process pressure vary, the receiver pressure will track the process with exactly the same variance, only at a pressure which is always less than the process pressure by the same amount at all points in time. In other words, the DeaeReturn Receiver will always maintain a constant pressure differential, regardless of what the process is doing; the result is uninterrupted flow of condensate in normal running situations.

Deaerator Section

A Stickle 240/250/275 Series deaerator operates at a minimum of 5 psig and 227 degrees F. The deaerator is designed to maintain a dissolved oxygen level of no more than 0.005 cc/l, with a negligible level of carbon dioxide.

  1. Feedwater, containing non-condensable corrosion agents found in all water supplies, enters the vessel through pressure-compensated, spring-loaded valves.

  2. Deflectors on each valve spread feedwater out into a thin, flat sheet of small droplets.

  3. Steam rises to surround the water droplets and heats them to a temperature relative to the pressure being maintained on the unit.

  4. Steam condenses and falls with feedwater onto a large cone, which carries the water to the tray section below the conical outlet.

  5. Heated feedwater is ready for agitation scrubbing by steam.

  6. Feedwater cascades over a series of properly sized trays, all arranged in rows, one above the other and all lying on the same axis. Each row of trays is staggered so the feedwater always falls on the center of each of the trays in next row.

  7. As feedwater moves downward through the rows of trays, the scrubbing of the rising steam removes non-condensable oxygen & carbon dioxide gases.

  8. These non-condensable gases are carried by the steam to the vent condenser, where the steam condenses and the gases are removed through a temperature-controlled orifice.

  9. Deaerated feedwater flow into the boiler cycle, minimizing corrosion potential.

High Pressure Receiver Section

The Stickle High Pressure Receiver is designed for processes which operate at 75 psig and higher. The function of the Stickle High Pressure Receiver is to return all available process condensate to the boiler, and to recycle all the available heat energy which that condensate possesses. By contrast, many existing condensate return systems simply allow the condensate to drain into a receiver which is vented to the atmosphere, thereby permitting a substantial portion of the condensate to flash into steam which is totally lost to the surroundings. The Stickle TR 800 utilizing our special condensate piping design completely eliminates the loss of any condensate or the heat it contains.

CONTINUOUS BLOWDOWN HEAT RECOVERY SYSTEM

Blowdown Heat Recovery

As energy costs continue to soar, heat recovery from the continuous blowdown of your boiler is fast becoming one of the most cost effective areas of energy conservation. The Stickle Continuous Blowdown Heat Recovery System pays for itself through energy cost savings in weeks-not years. With the Stickle System you can be sure you are not draining dollars down the sewer. Just as important, you can also be sure you are achieving constant and metered removal of accumulated boiler solids. See our Continuous Blowdown Heat Recovery System Brochure for more.

The Operation

The Stickle Series 550 Continuous Blowdown Recovery System is designed to recover the heat from continuous blowdown in two stages. The first stage begins at the time the blowdown water is introduced into the flash tank via the blowdown flow control valve. The pressure of the blowdown is reduced from the boiler pressure to the flash tank operating pressure. At this point usually five to twenty percent of the blowdown is flashed into steam depending upon the specific conditions of the job. This liberated steam represents a major portion of the available blowdown heat. This steam may be used to supplement the heating steam in the deaerator or for any other process requiring low pressure steam.

The second stage consists of passing the remaining blowdown condensate through the shell side of a shell and tube heat exchanger. Feedwater make-up is circulated through the tube side of recover the remaining portion of available blowdown heat. The blowdown condensate is then discharged to the drain.

A Versatile System

The Stickle Steam Specialties Series 550 Continuous Blowdown Heat Recovery System is offered in a wide range of flow rates, boiler pressure, and blowdown tank operating pressures.

From top to bottom each Stickle Series 550 Continuous Blowdown Heat Recovery System is individually designed to meet your specific conditions.

  1. BLOWDOWN FLOW CONTROL– The standard mode of blowdown flow control is accomplished by the used of an 800 psig rated steel body manual globe valve. This valve is equipped with stainless steel trim, linear characteristic valve plug, and micrometer handwheel. If automatic control and modulation of blowdown is required Stickle Steam Specialties offers a continuous sampling conductivity controller. This controller constantly monitors, through an orificed line, the conductivity of the blowdown. Condutivity level is a direct indicator of the dissolved solids concentration. A preselected setpoint determines the level of allowable concentration. The Controller comopares the current solids concentration to the set-point and transmits a pneumatic output signal to a diaphragm control valve, regulating the flow of blowdown into the blowdown tank. This controller is available with either a meter or a 60 day recording chart.

  2. BLOWDOWN TANK– The Stickle system blowdown tank utilizes a tangential inlet design. This design provides manimum efficiency in steam separation while maintaining compactness of size. Every Series 550 blowdown tank is designed, fabricated, inspected, and stamped in accordance with ASME pressure vessel requirements, and, if applicable, any local, state, and federal codes.

  3. HEAT EXCHANGER– Every shell and tube heat exchanger utilized in the Series 550 line is equipped with type 304 stainless steel tubes to prevent corrosion. Both shell and line tubes are designed, fabricated, inspected, and stamped for 150 psig in accordance with ASME Section VIII. Each heat exchanger is individually sized for maximum heat transfer and minimum pressure loss for each job. Each unit is furnished with complete bypass piping and isolation valves around the heat exchanger for easy maintenance without system shutdown. Each Unit is also furnished with piping provisions for installation of backflush piping for purging of heat exchanger with fresh water. If Desired, complete backflush piping may be provided with the unit.

  4. LIQUID SEAL/LEVEL CONTROL– A constant liquid level is maintained in the blowdown tank at all times. On standard units this is accomplished by an external pneumatic displacer type level control. This controller modulates, via a 3 to 15 psig air signal, a diaphragm valve on the blowdown condensate outlet of the heat exchanger, This arrangement enables the heat exchanger to be totally occupied with liquid at all times. The liquid seal eliminates the occurrence of destructive flashing forces within the heat exchanger. Where instrument air is not available, the Stickle Series 550 may be equipped with direct acting mechanical lever type ball float and valve actuation.

200 SERIES SPRAY TYPE DEAERATORS

200 Series Spray Type Deaerators

The Stickle Deaerating Feedwater Heater evolved from our first Open Coil Feedwater Heater patented in 1901. The first generation of Stickle Feedwater Heaters were employed to capture calcium in boiler feedwater. It was later learned the feedwater heater served the more important role of oxygen and carbon dioxide removal. The extraction of these harmful gases is the primary function of all Stickle Deaerators. Removal of these non-condensable gases from make-up water for boiler feed, protects boiler, condensate return lines, piping and pumps from corrosive gases. See our 200 Series Spray Tray Type Deaerators Brochure for more.

Stickle Series Deaerators

Stickle Deaerators are designed to completely remove oxygen and carbon dioxide to the accepted level of “zero”. “Zero” is defined by the indigo carmine test method as soluble oxygen is not to exceed .005 cc per litre and soluble carbon dioxide to be virtually zero.

  • Engineered for precise, dependable performance over wide load shifts
  • Custom-designed to user specifications…to meet your exact needs
  • Built to exceed ASME Code, Section VIII, Division I…for years of reliable operation
  • Backed by the industry’s ONLY 10-year non-prorated standard warranty

The Function

The Stickle Spray Type Deaerator is designed to completely remove oxygen and carbon dioxide to the accepted level of “zero”. “Zero” is defined by the indigo carmine test method as soluble oxygen is not to exceed .005 cc per litre and soluble carbon dioxide to be virtually zero.

The Operation

The Stickle Spray Type Deaerator operates through a two stage design.

STAGE 1, the cold water make up and low pressure return enter the deaerator through the spray heads which are of a pressure and flow compensating, spring loaded type. Here, in the direct contact internal vent condenser, the cold water and low pressure returns are broken down for initial heating and deaeration. Most of the corrosive gases are released at this stage and are vented to atmosphere through the automatic air vent valve.

STAGE 2, a supplemental heating and agitating process, is where the final deaeration is accomplished. During Stage 2 the final deaeration is provided by the use of a spring loaded steam atomizer. The high velocity steam blasts the water gravitated from Stage 1 to this point. Remaining amounts of oxygen and carbon dioxide are released, and evacuated, again through the automatic air vent valve. The automatic air vent valve minimizes the amount of steam that escapes the vessel, but insures full venting of all non-condensable gases.

Maintaining Your Stickle DEAERATOR

The Stickle Spray Type Deaerator is designed and constructed for easy maintenance and durable service for years. All internals contacting non-deaerated water are constructed of 12 gauge, Type 316 stainless steel material. All component parts of the Spray Type Deaerator are easily removable from the unit. The spray heads and steam atomizer are removable from the exterior of the vessel in order to facilitate periodic maintenance without entering or draining the vessel. The internal stainless steel pan assembly knocks down to pass through the manway.

    TR 800-V150 HIGH PRESSURE CONDENSATE RETURN

    TR 800-v150

    The Stickle TR 800-V150 High Pressure Condensate Recovery System has become the system of choice among plant engineers and boiler room personnel alike. Its design has been honed and refined to become the absolute best system for the complete and economical recovery of high pressure and temperature condensate from your process. Its simplicity of design remains unsurpassed, having been approved and confirmed time after time by the toughest of all possible tests, real world applications. See our TR 800-V150 High Pressure Condensate Return Brochure for more.

    The Function

    The Stickle TR 800-V150 is designed for processes which operate at 75 psig and higher. The function of the Stickle TR 800-V150 is to return all available process condensate to the boiler, and to recycle all the available heat energy which the condensate possesses. By contrast, many existing condensate return systems simply allow the condensate to drain into a receiver which is vented to the atmosphere, thereby permitting a substantial portion of the condensate to flash into steam which is totally lost to the surroundings. The Stickle TR 800-V150 completely eliminates the loss of any condensate or the heat it contains.

    The Operation

    The principle of operation of the Stickle TR 800-V150 is extremely simple. The movement of a fluid is dependent upon a difference in pressure between its source and its destination. The Stickle TR 800-V150 is designed to maintain a constant positive pressure differential between the process and the receiver. The amount of pressure differential is sufficient to allow complete evacuation of condensate, yet small enough so as to prohibit any substantial portion of the condensate from flashing. The normal one to three percent resultant flash steam is fed into the user’s Deaerator, or other system requiring steam as a supplement to the normal steam supply. The result is that all of the heat of the condensate is kept within the system.

    The pressure and temperature of condensate in the Stickle TR 800-V150 high pressure receiver is usually within 30 psi and 20-25 degrees F. of the actual pressure and temperature of water within the boiler itself. Since the Stickle TR 800-V150 is a closed loop system the condensate can be pumped directly back to the boiler, without need for deaeration.

    One important feature of the Stickle TR 800-V150 is that should the process pressure vary, the receiver pressure of the Stickle TR 800-V150 will track with exactly the same variance, only at a pressure which is always less than the process pressure by the same amount at all points in time. In other words, the Stickle TR 800-V150 will always maintain a constant pressure differential, regardless of what the process is doing. Since movement of condensate is dependent upon a difference in pressure from one point to another, rather than the absolute pressure at either point, the result is uninterrupted flow of condensate in every situation.

    The Stickle Concept

    The Stickle TR 800-V150 High Pressure Condensate Recovery System will function satisfactorily with existing condensate equipment and piping. However, it may be found that the improvement potential of the Stickle TR 800-V150 may be restricted by ongoing problems of the existing condensate return system, such as trap failure or inadequate piping. The Stickle TR 800-V150 may be made an integral part of a comprehensive condensate return system engineered and supplied in its entirety by Stickle. This system would encompass the entire condensate return path beginning at the process connection including all condensate return components and the Deaerator. The advantage to you is that Stickle provides single source responsibility for the whole condensate return function, from the process straight through to the boiler.

    The Benefits

    The benefits of utilizing the Stickle TR 800-V150 High Pressure Condensate Recovery System when compared to a boiler feed system or low pressure Deaerator alone are very substantial:

    1. Worry-Free Condensate Removal: The fundamental operating principle of drainage for the Stickle TR 800-V150 provides fail-safe condensate removal from the process at all times.
    2. Energy Savings: By containing all the heat inherent in the condensate, the Stickle TR 800-V150 payback from fuel savings is stunningly short.
    3. Water Savings: Make-up water replacing lost flash steam is eliminated.
    4. Reduces Deaerator Load: All process condensate bypasses the Deaerator. The make-up water requirement is substantially lowered. The Deaerator, or boiler feed system, only needs to handle just make-up water for that water which is lost only in the process itself plus boiler blowdown.
    5. Reduces Boiler Blowdown: Since the make-up demand is reduced, a representative amount of boiler blowdown flow is eliminated.
    6. Reduces Boiler Strain: The water that is pumped to the boiler from the Stickle TR 800-V150 is very close to the temperature of the water within the boiler itself. The boiler can offer much lower heat input to the feedwater to raise it to boiler temperature and pressure.
