What is the function of a steam trap?

The function of a steam trap is to remove condensate and air from steam systems. In steam applications, steam traps play a critical role in the efficient operation of the system by allowing condensate—water produced when steam cools and condenses—to be expelled while preventing the loss of live steam. This is important because the presence of condensate can lead to water hammer, reduced heat transfer efficiency, and even eventual equipment failure. Moreover, steam traps also serve to expel air and other non-condensable gases that can accumulate in the system, which can hinder steam flow and reduce efficiency.

By maintaining proper steam quality and ensuring that condensate is effectively removed, steam traps help to optimize heating processes, improve energy efficiency, and enhance the overall performance of steam systems. Understanding the role of steam traps is essential for effective steam system management and ensuring that equipment operates safely and efficiently.
