What is the primary function of a steam trap?

The primary function of a steam trap is to act as an automatic valve for the release of condensate and air from steam systems. Steam traps are essential components that ensure efficient operation by allowing condensate—water produced when steam cools and condenses—to drain from the system while preventing the escape of live steam. This process is crucial for maintaining system efficiency and avoiding potential issues like water hammer, which can occur if condensate builds up in the system.

Additionally, steam traps help in air removal, which is necessary to maintain the desired steam pressure and temperature within the system. By removing air and non-condensable gases, steam traps enhance the thermal performance of the steam system and improve heating efficiency. Thus, the key role of a steam trap is its ability to manage condensate and air, ensuring optimal functioning of steam systems.
