What is the purpose of a steam trap in a steam system?

In a steam system, the function of a steam trap is crucial for maintaining efficiency and performance. The correct answer describes the primary role of a steam trap accurately. It is designed to remove condensate and air from the steam system while preventing the loss of live steam.

When steam is generated, it can condense back into water (condensate) as it releases its heat energy. If this condensate is not removed, it can lead to waterlogging and reduced heat transfer efficiency. Additionally, air and other non-condensable gases can accumulate in the system, which can also hinder steam flow and efficiency. The steam trap allows condensate and air to escape, ensuring that only steam remains in the system. This function helps maintain optimal operating conditions, enhances energy efficiency, and avoids potential damage from water hammer or other issues caused by condensate build-up.

Other functions, such as increasing steam pressure, maintaining water levels, or enhancing combustion efficiency, do not apply to the steam trap's specific role within steam systems. Each of these tasks might be performed by different components in the steam system but is not related to the operation or purpose of a steam trap.
