What is Steam trap

Steam trap is a valve that can automatically remove steam condensed water and non-condensable gases such as air in heating equipment or steam pipes, and does not leak steam.
The three important functions of steam traps are:
1.Discharge condensate as soon as it is formed (unless it is desirable to use the sensible heat of the liquid condensate)
2.Have a negligible steam consumption (i.e. being energy efficient)
3.Have the capability of discharging air and other non-condensable gases.
Steam traps are widely used in various industries such as petrochemicals, food and beverages, pharmaceuticals, textile printing and dyeing, electric power, tobacco, etc., and play a great role in energy saving and emission reduction.
No steam system is complete without that crucial component Steam Trap.
There are three types of steam trap,each type uses a different working principle to remove condensed water and non-condensable gases.
1. Mechanical steam trap
Mechanical steam traps rely on the density difference between steam and condensate to work. Mechanical steam traps are divided into inverted bucket steam trap and floating ball steam trap.
2. Thermostatic steam trap
The thermostatic steam trap relies on the temperature difference between steam and condensate to work. Thermostatic traps are divided into bimetallic steam traps andfilm box steam traps.
3. Thermodynamic steam trap
The thermodynamic steam trap relies on the difference of flow velocity between steam and condensate to work.
