What is the main purpose of a steam trap?

The main purpose of a steam trap is to effectively remove condensate and air from the steam system while preventing the loss of steam. In steam systems, when steam is used to transfer heat, it cools and condenses back into water (known as condensate). If this condensate is not removed efficiently, it can lead to water logging, decreased efficiency, and potential damage to the system.

Steam traps serve as critical components that allow condensate to exit the system while keeping the steam contained. By doing so, they maintain the proper steam pressure and temperature levels in the system, ensuring that it operates efficiently and effectively. They also play an essential role in removing air and other non-condensable gases that may hinder the performance of the system.

The other options do not encapsulate the primary function of a steam trap. Monitoring steam pressure pertains to pressure gauges, enhancing water circulation relates more to pumps and water systems, and regulating temperature directly involves thermostats and control systems rather than the specific role of a steam trap.
