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 (unless it is desirable to use the sensible heat of the liquid condensate)
- Have a negligible steam consumption (i.e begin energy efficient)
- Have the capability of discharging air and other anon-condensate gases
