What is the purpose of steam traps in steam lines?
To remove chemicals
To remove sludge
To remove condensate and non-condensibles
To remove excess heat
The correct answer is: To remove condensate and non-condensibles
The purpose of steam traps in steam lines is to remove condensate and non-condensibles. Steam traps are essential components of a steam system because they allow condensate, which is water formed when steam cools, to be efficiently drained from the system. This prevents water from accumulating, which could lead to water hammer, reduced efficiency, or damage to equipment. In addition to managing condensate, steam traps also serve to remove non-condensable gases, such as air and other gases that may have entered the system. These gases can reduce the efficiency of heat transfer and lead to issues such as corrosion or equipment failure if not properly managed. Therefore, the primary function of a steam trap is to ensure that only steam remains in the system, which optimizes performance and maintains safety. The other options, while they address different aspects of system maintenance, do not accurately capture the main function of steam traps within steam lines.
