Proper steam trap maintenance is essential to a steam system. Faulty steam traps not only waste energy, they can contribute to pipe erosion due to poor water quality and contaminants allowed to pass down stream. Faulty steam traps can negatively affect product quality in various processes such as paper, food or chemicals, and even add to environmental pollution. Steam Traps should be inspected routinely.
Steam pressure reduction is the lowering of the steam pressure at the boiler plant by means of the pressure setting on the boiler plant master control. Steam pressure reduction affects mainly the high pressure part of the steam system.
Thermostatic Steam Trap. It is a stainless steel body balanced pressure thermostatic steam trap with a built in strainer, ideal for removal of condensate from instrumentation tracing lines. Available in forged carbon steel & SS body.
the Boiler Operation Condensate Steam is comprised of two types of energy; latent and sensible energy. When steam is supplied to a process application (heat exchanger, coil, tracer, etc.) the steam vapor releases the latent energy to the process fluid and condenses to a liquid better known as conden-sate. The condensate contains the sensible energy from the steam vapor.

A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Most steam traps are nothing more than automatic valves. They open, close or modulate automatically. The three important functions of steam traps are: Discharge condensate as soon as it is formed Have a negligible steam consumption Have the capability of discharging air
sections of this Code specify the rules by which steam boilers, pressure vessels and connecting piping are to be designed, constructed and installed.

A steam trap is an automated device designed to remove condensate from a steam-containing enclosure while retaining live steam at the same time, giving the live steam more surface to maximize heat transfer efficiency. By removing condensate, steam traps allow it to be collected and re-used.
A trap that is blowing steam can also cause water hammer. Blowing traps create back pressure in the condensate system piping. If condensate piping is already undersized, the problem will be compounded by the additional pressures found by the faulty traps.
Jun 23, 2014 · Why you can't use high-pressure steam boilers on low-pressure steam systems. Why you can't use high-pressure steam boilers on low-pressure steam systems. Toggle navigation Answers in minutes. Sign into the forum Contractor Login. Search. The contractor had changed some of the steam traps from high pressure to low pressure by replacing the
The Ins and Outs of Residential Steam Boilers. Steam boilers operate like a tea kettle. As water heats to a boil it builds pressure as it reaches the state of steam. Unlike hot water boilers which rely upon a pump to circulate the hot water, steam boilers use this pressure to move the steam through the piping system.
Apr 13, 2017 · The open bucket in an inverted bucket trap can rattle but the bucket does not collapse. This is why the bucket type trap is often referred to as a lifting trap. In general, regardless of pressure, when using steam modulating control valves with heat exchangers, avoid lifting out of the steam trap. Next week, we will examine condensate return pumps.
Jun 26, 2000 · Imagine 15-psi steam blowing past a failed trap into the condensate return line. Now the return line is pressurized to 15 psi. The pressure on the discharge side of any trap draining into the same line as the failed trap is now much higher than anticipated, so we no longer have a pressure differential across the other traps.

Note:to get say 1000 PPH of steam out you need to put in 1000 PPH of water! Since you usually talk about gpm to the boiler, a rule of thumb is divide the number of PPH of steam out by 500 and that is the number of gpm you need to put into the boiler. 1000 PPH steam/500 = 2 gpm into the boiler.
Steam quality. A separator is a body in the pipeline which contains a series of plates or baffles which interrupt the path of the steam. The steam hits the plates, and any drops of moisture in the steam collect on them, before draining from the bottom of the separator. Steam passes from
A: A Steam Trap performs two functions. First, it is an air vent. As steam fills the pipes on startup it must displace air, and during equipment operation all air formed must be vented. Secondly, it is a water outlet valve, which allows residual water to be removed from the steam system faster than it is formed.
Dec 01, 2011 · Venturi or Orifice Traps. Steam and condensate pass through the Venturi nozzle steam traps by a series of staged steps. The denser liquid (condensate) throttles the venturi nozzle, which keeps the steam from escaping. Erosive eddy currents are eliminated and any contamination is carried away with the condensate.
Clayton Steam Generators are a once-through, forced-flow, water tube boiler utilizing a steel helical coil heat exchanger. Steam House Africa is an appointed technical centre for ETC -
The steam trap is designed to close in the presence of steam and drain the condensate. As the steam condenses into a liquid, it gives up its latent heat. The latent heat results in lb, for lb the steam releasing more energy than the water. The steam traps purpose is to prevent the steam leaving the system before it gives up its latent energy
May 11, 2011 · Expand the tube/pipe diameter after the discharge connection of the steam trap. For example, a 1 in. steam trap discharge should connect into tubing/piping with an expanded diameter of 1.25 in. or 1.5 in. Connect steam traps with connection sizes of 1 in. or smaller to the tubing or piping with universal mounts.
Flash steam, which is formed when a portion of the high pressure condensate discharged from a steam trap re-evaporates, is separated from the condensate and piped away from the top of the tank. The remaining condensate drains from the bottom of the vessel to a stream trap.
Steam Operated Pump Trap Steam Traps can discharge condensate only when the inlet pressure is higher than the outlet pressure i.e when there is a positive differential pressure across the trap. In certain applications which are temperature controlled, there is a possibilty of the process side pressure becoming either equal to or less than the
Steam leaves the boiler through piping to transfer heat to something; usually a heat exchanger or steam jacket. When the steam condenses in the pipe it is called condensate. This condensate water has very little impurities in it.
The thermostatic trap also functions as an air vent. So the first thing that happens is that the air is vented out of the system’s steam trap. If the steam trap fails in a closed position, the air is trapped in the radiator and it stays cold. This problem is rare, but it can occur.

To do this most steam systems have multiple steam traps plumbed in throughout the piping system. These steam traps were installed to remove the liquid condensate and air from the pipe so that pipe stays filled with “dry” steam. As the trap allows the dry steam to pass, it redirects the hot liquid condensate to a condensate receiver where it can be reused in the boiler.
In small steam plants, a portion of the steam generated by the boiler is used to operate the deaerator if "waste steam" is not available. Failure to maintain and properly operate the deaerator can lead to early failure of the boiler, steam using equipment, and the steam and condensate piping.
