A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Steam traps are nothing more than automatic valves. They open, close or modulate automatically. [1] The three important functions of steam traps are:
Steam trap: Viewing glass Pressure reducing valve: Valve: Gate valve: Control valve: Manual valve Check valve: Needle valve: Butterfly valve: Diaphragm valve: Ball valve: Check valve: Back draft damper Bag Gas bottle: Globe valve: 3-way valve Piston or reciprocating compressor: Relief valve: Rupture disc: Turboexpander: Centrifugal pump ...
It started to manufacture steam traps in United Kingdom under the Spirax brand name in 1932 and was first listed on the London Stock Exchange as Spirax-Sarco Engineering in 1959. [4] In 1960, a range of self-acting pressure controls are introduced for the first time: then in 1963, it bought Drayton Controls, a control valve and instrumentation ...
The steam strips the dissolved gas from the boiler feedwater and exits via the vent valve at the top of the domed section. If this vent valve has not be opened sufficiently, the deaerator will not work properly, resulting in feed water with a high oxygen content going to the boilers.
Only when air evacuation is complete does the discharge stop. Flow is usually controlled by a steam trap or a solenoid valve, but bleed holes are sometimes used. As the steam and air mix, it is also possible to force out the mixture from locations in the chamber other than the bottom. Steam pulsing:
Removable insulation blankets can be installed on many indoor and outdoor components such as boilers, steam traps, pipes, valves, flanges, and more. [2] They are typically used to prevent heat from escaping hot components; however, they can also be used to prevent freezing or warming of cold components.

Unlike the superheater, the steam drier does not attempt to raise the temperature of the steam significantly beyond the boiling point. Steam generator Steam separator Suction valve an automatic non-return valve, which opens when the boiler is at less than atmospheric pressure. This avoids any risk of vacuum collapse, when a hot boiler is ...
