The primary function of a steam trap is to remove condensate and air from steam systems without losing steam. In steam systems, when steam is utilized, it condenses back into water as it releases its heat to the system. This condensate needs to be continuously removed to maintain the efficiency and effectiveness of the steam system.

A steam trap enables this by allowing water (condensate) and any accumulated air to escape while preventing the loss of live steam. This is crucial because if steam were to escape, it would result in energy loss and decreased system efficiency. The steam trap operates based on pressure and temperature differences, ensuring that it can distinguish between steam and condensate, allowing it to function appropriately.

Other options do not align with the main function of a steam trap. For instance, condensing steam back into water does happen in the system but is not the trap's role; rather, it's a result of the heat exchange process. Injecting steam into the system is completely separate - this process typically involves valves and steam generation, not traps. Increasing the pressure in the steam line relates to pressure control mechanisms and pumps, not steam traps. Thus, the steam trap's unique ability to handle condensate and air while preserving steam is what makes it
