What are the two primary functions of a steam trap?

The two primary functions of a steam trap are to remove air and condensate. Steam traps are essential components in steam systems because they help maintain the efficient operation of the system by allowing condensate and air to escape while preventing the loss of live steam.

When steam is produced and used in a system, it eventually condenses back into water (condensate). If this water accumulates in the steam lines, it can lead to reduced efficiency, potential damage to equipment, and even safety hazards. Air, if present in the system, can also hinder the efficient flow of steam. By removing both condensate and air, steam traps ensure that the system operates efficiently and effectively, maintaining the desired temperature and pressure for cooking or heating processes.

Generating steam, adding chemically treated water, and regulating steam pressure are not the primary functions of a steam trap, although they may be part of the larger steam system operations. However, the primary focus of a steam trap is its role in keeping the steam system clear of obstructions caused by air and water accumulation.
