What happens when a steam trap continuously blows through?

When a steam trap continuously blows through, it indicates that steam is not being properly condensed and returned to the boiler system, leading to steam venting directly from the condensate tank. A properly functioning steam trap should only allow condensate and non-condensable gases to pass through while retaining steam, ensuring efficient system operation. Continuous blow-through can signify a malfunction, causing steam to escape and resulting in a loss of thermal energy that should otherwise be utilized for heating or process purposes. This action represents a significant loss of steam and can affect overall system efficiency.

In contrast, the other outcomes, such as water leaking from the system, reduced boiler pressure, and increased fuel wastage, can be consequences of steam loss but are not direct outcomes of a steam trap blowing through. The primary and most immediate effect is the venting of steam, leading to energy and cost inefficiencies.
