STEAM TRAP SELECTION GUIDE

As the USAs leading provider of steam system solutions, Spirax Sarco recognizes that no two steam trapping systems are identical. Because of the wide array of steam trap applications with inherently different characteristics, choosing the correct steam trap for optimum performance is difficult. Waterhammer, superheat, corrosive condensate, or other damaging operating characteristics dramatically affect performance of a steam trap. With over 80 years of experience in steam technology, Spirax Sarco and Steam Supply are is committed to helping its customers design, operate and maintain an efficient steam system. You have our word on it!

sTEAM TRAPs
First, a denition of a steam trap may be in order to fully understand the function of this piece of equipment. A steam trap is an automatic valve designed to stop the ow of steam so that heat energy can be transferred, and the condensate and air can be discharged as required. If we break this denition down into sections, it is rst of all an automatic valve. This infers that there is some form of automatic motion that must take place. It is designed to stop the ow of steam so that heat energy can be transferred. This portion of the description is such that it would imply the transmission of energy whether by owing down a distribution pipe or giving up energy to a product in a heat exchanger. The denition also continues to say discharge condensate and air as required. This portion of the denition implies that some types may handle differing amounts of either condensate or air, or even a combination of the two. In the beginning, steam traps were manually operated valves. The major problem with this type of condensate drainage system is the variation to changing condensate ows. Condensate, you will recall, is steam that has given up its enthalpy and reformed into water. The amount of condensate being created varies in many different ways. A xed position of a block valve or xed hole in a drilled plug cock valve cannot adjust automatically to the varying conditions of condensate load. This method of condensate removal would warrant an operator be present much of the time to correct the setting of the valve. If condensate was allowed to back up, less heat transfer would take place, causing production to fall off. If, on the other hand, the condensing load was less, the operator would have to close the valve to the point that steam was not continuously being released. Because of the changing nature of condensing loads, this would be a full-time job. True steam trap operation will fall under one of the following three categories: 1. Mechanical or Density 2. Thermostatic or Temperature Controlled 3. Thermodynamic or Velocity These categories of traps have distinctive operating characteristics and work most efciently when used for their designed purpose. It would stand to reason that steam traps evolved with industry and demand. There are really only three applications for steam traps: drip stations (located on steam delivery lines), tracing (steam lines designed to maintain a product temperature or keep a liquid system from freezing) and process (steam used specically for heating products such as air, process uids, foods etc.). These differing applications will be discussed later. Our purpose now is to explore the operating characteristics of traps and where they fall within each category.

THERMODYNAMIC STEAM TRAPs

This type of steam trap uses velocity to open and close a valve. The valve in this type of trap is a free oating disk which sits on two seating surface areas. One area is an inlet orice and the other are multiple outlet orices located in an adjacent ring. It is a fairly simple trap to understand. On start-up, the disk is forced upward and off the seating surface rings by the ow of air and condensate. Condensate and air are discharged from the trap. Condensate force is directed to the center and under the disk chamber and is exposed to the outlet ring of orices. It recognizes a lower downstream pressure within the chamber and ashing of the condensate occurs. Flashing is natures way of cooling condensate back to the saturation temperature at which it can exist as liquid at the lower pressure. The excess heat energy in the condensate that cannot exist as liquid at the lower pressure and temperature generates steam at the lower pressure and expands. This expansion causes an increase in the velocity of ow between the bottom of the disk and the seating surfaces, which in turn causes a negative pressure to be sensed on the bottom of the disk beginning to pull it down onto the seating surfaces. Some of the ash steam that is being created ows around the sides of the disk to the top surface of the disk. This ash steam is trapped between the top of the disk and the cap of the trap and pressure develops in this space, pushing the disk down onto the seating surfaces. When the pressure in the cap chamber is great enough to overcome the inlet pressure of the condensate on the bottom of the disk, the trap snaps closed. The trap will remain closed until the pressure in the cap chamber has dropped to below the inlet pressure. Then the cycle will repeat itself. The cap chamber pressure drops due to natural heat losses from the cap to the ambient conditions, condensing this steam. This type of trap operates on a cyclical pattern, either open or closed. Because the trap is closed by ash steam created from hot condensate, there is a small amount of subcooling of the condensate and back up of condensate in the system. The subcooling ranges between 2 to 10F below saturated steam pressure and temperature relationship. The advantages of this type of trap are they are not damaged by waterhammer or freezing and will work consistently throughout their pressure range (up to 1750 PSIG). They can be utilized on superheated steam systems without any problems, and they are easily tested, installed and maintained. This is the only type of steam trap that will give an indication of wear before nal failure occurs. The cycling rate increases with wear and gives a distinct audible clicking sound (rapid cycling). The disadvantages to this trap are that it does not operate well at extremely low pressures (below 3.5 PSIG) or extremely high percentages of back pressure (around 80%). They are also limited in their air handling capability. This type trap is ideally suited for steam main distribution drainage and tracing applications.

INVERTED BUCKET sTEAM TRAPs

The second mechanically operated steam trap is the Inverted Bucket type of trap. In this trap, the operating force is provided by steam entering and being contained within an inverted bucket causing it to oat in condensate that surrounds the bucket itself. The bucket is attached to a lever and pivot point similar to that in the F & T. The valve head and seat, however, are located at the top of the trap. It requires water being present within the body in order for the bucket to have something in which to oat. This is called the prime. When steam is rst turned on, air is allowed to ow to the trap. This air is captured within the bucket and ows out through a hole in the top of the bucket known as the vent hole. Air passes upward through the hole, through the prime, and collects at the top of the trap. Since the system is building pressure, the air is at its most compressed state. This puts a downward force on the prime and pushes it back up into the bucket. As this bucket lls with water, it loses buoyancy and sinks in the surrounding liquid. In doing so, it pulls the valve head off of the valve seat and allows the collected air to discharge. Flow from under the bucket starts again. This allows either more air or steam to begin to enter the trap body. If it is more air, the sequence is repeated. If it is steam, however, the sequence is different. Steam passes through the bucket vent hole to the top of the trap and is condensed by heat losses from the trap body, in particular the cap or top. This loss is necessary to keep steam and condensate coming to the trap. As condensate enters under the bucket, it lls the space and again the CALL STEAM SUPPLY FOR THE CURRENT INFORMATION bucket loses buoyancy and sinks. Discharge ow SHEET LISTED IN EACH PRODUCT DESCRIPTION. is rst downward from under the bucket, and then upward to the discharge orice. The biggest advantage to this type of trap is its ability to withstand high pressures. It has a reasonable degree of tolerance to waterhammer damage but suffers from freeze damage. In the case of freezing, however, most of the damage is done to the body of the trap rather than to the mechanism or oat. The disadvantage to this trap type is its limited ability to discharge air and other non-condensable gases. This is due to the small vent hole and low differential pressure driving the air through it. It is suspect at times to rapid pressure changes in the system due to the requirement of a prime being maintained internally for proper operation. The prime water seal is at saturated steam pressure/temperatures and if the steam pressure drops rapidly due to load changes of equipment, the prime has a tendency to boil off (ash). Without the required prime, this type of trap fails open. This type of trap is most appropriately suited for stable, steady load and pressure conditions such as one would nd on a steam distribution system.

The difference between the steam pressure at the trap inlet and How size the totalto back pressure, including that due to lift after the trap, is the pressure.the The quantity of condensate should be The differential difference between steam pressure at the trap inlet and multiplied by the appropriate safety factor to lift produce thetrap, sizing the total back pressure, including that due to after the is load. The trappressure. may now be quantity selected the differential the differential The of using condensate should be pressure the sizing load. safety factor to produce the sizing multipliedand by the appropriate Note: pressure to the trap should exceed the load. The Theinlet trap may now besteam selected using never the differential Maximum Operating Pressure pressure and the sizing load. (PMO) of the selected trap, regardless of differential Note: The inlet pressure pressure. to the steam trap should never exceed the Maximum Operating Pressure (PMO) of the selected trap, regardless of differential pressure. Example A steam trap is required to drain 2,000 lb/h of condensate from a Example Unit Heater receiving steam at 100 psig. A steam trap is required There is a lift after the trapto ofdrain 10 ft. 2,000 lb/h of condensate from a Unit Heater receiving steam Inlet Pressure 100 psig at 100 psig. There is a ft. lift= after the trap of 10 ft. Lift 10 5 psi (approximately) Inlet Pressure 100 psig Therefore, Lift 10 ft. = 5 psi (approximately) Differential Pressure 100 psi - 5 psi = 95 psi Therefore, Quantity 2,000 lb/h Differential Pressure 100 psi - 5 psi = 95 psi Safety Factor 2:1 Quantity 2,000 lb/h Sizing Load 4,000 lb/h Safety Factor 2:1 A 1-1/4" B4-125 will handle 7,590 lb/h at 95 psi differential Sizing Load 4,000 lb/h pressure. A 1-1/4" B4-125 will handle 7,590 lb/h at 95 psi differential pressure.
