What is the primary function of a steam trap in a boiler system?

The primary function of a steam trap in a boiler system is to remove condensate and non-condensable gases. Steam traps are essential components that ensure the efficient operation of steam systems by allowing condensed steam (water) to escape while preventing the loss of live steam. When steam is used in various applications, it cools down and condenses back into water. If this condensate is not removed promptly, it can lead to various issues such as water hammer, reduced heat transfer efficiency, and potential damage to piping and equipment.

The steam trap plays an instrumental role by opening to let the condensate out and closing to retain steam within the system. Additionally, it can remove non-condensable gases, which, if present, can also hinder the efficiency of heating systems and lead to corrosion.

While increasing steam pressure, cooling down steam, and measuring steam temperature are important aspects of boiler operations, they are not the primary functions of a steam trap. Instead, the trap focuses specifically on maintaining the steam system's performance and integrity by managing condensate and gas removal effectively.
