How Does a Steam Trap Work?

A steam trap is an essential device in steam systems, which removes condensate, air, and other non-condensable gases without allowing live steam to escape. Its main purpose is to allow only condensate and gases to leave the system, ensuring efficiency and energy conservation.

Working Principle of a Steam Trap

Steam traps operate on various principles, such as:

  • Mechanical Operation: Depends on buoyancy to sense the level of condensate and release it as needed.
  • Thermodynamic Action: Works on pressure and temperature difference to release condensate.
  • Thermostatic Mechanism: Senses the change in temperature and opens/closes in response.

Note: Proper selection of steam traps improves system performance, minimizes energy loss, and avoids inefficiencies such as water hammer or steam leakage.
