What is thermodynamics steam trap?

What is thermodynamics steam trap?

The thermodynamic trap is an extremely robust steam trap with a simple mode of operation. The trap operates by means of the dynamic effect of flash steam as it passes through the trap, as depicted in Figure 11.4. 1. The only moving part is the disc above the flat face inside the control chamber or cap.

What does thermostatic trap mean?

Thermostatic traps are normally open allowing fast venting of air during start-up. During start-up, cold condensate drains through the trap. During operation, thermostatic traps find an equilibrium point to drain condensate approximately 10° to 30°F below saturation at continuous flow.

What is a steam trap and how does it work?

Steam traps are a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. In industry, steam is used regularly for heating or as a driving force for mechanical power.

Should steam traps be insulated?

What about steam traps? Steam is supplied to the inlet of a steam trap, so the inlet piping should also be insulated to prevent radiant heat losses.

Why do you need a steam trap?

The steam trap is an essential part of any steam system. It is the important link between good steam and condensate management, retaining steam within the process for maximum utilisation of heat, but releasing condensate and incondensable gases at the appropriate time.

What is the best type of steam trap?

Applications Suited to the Disc-Type They are commonly used for steam mains drainage or high temperature tracing discharge. However, Free Float® traps are more energy efficient and durable in the same services, so typically disc traps are recommended as a second choice in those applications.

Why do steam traps fail?

Steam trap failure is caused by improper removal of the condensate. When the steam trap shows signs it can no longer remove condensate from the steam system efficiently, it’s a sign the traps are failing. Increased inefficiency means wasted fuel and an overall increase in production costs.

What does a thermostatic trap do?

Thermostatic operation. NOTE: Thermostatic traps can also be used for venting air from a steam system. When air collects, the temperature drops and the thermostatic air vent automatically discharges the air at slightly below steam temperature throughout the entire operating pressure range.

Does a steam trap remove condensate?

A steam trap is a device that removes condensate from a steam system. A typical steam system will have many steam traps – they are placed at 50-150′ intervals in straight pipe, after every heat exchanger (where the work gets done), and at every location where there is a change of elevation or pressure.

How does a steam trap work?

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.
