The impact of a higher drainage capacity of a steam trap
Thread Content
Does choosing an excessively high drainage capacity for a steam trap have any effects? Will it waste steam? Will using a lower operating backpressure than that selected result in steam waste?
This depends on the quality and principle of the steam trap.
When selecting a steam trap based on the pipeline, the manufacturer plays a role in this process; following their recommendations prevents the selection of a too-large unit. Usually, the problem arises from the inability to drain the condensate or from liquid slugging. When the operating back pressure is low during selection, a proper choice will prevent steam waste; if the operating back pressure is high, the condensate cannot be discharged
Choosing a larger steam trap will result in frequent operation, increased wear, and leakage. When the back pressure is low, the drainage capacity of the steam trap increases; if this capacity is much higher than the actual amount of condensate produced, the situation described earlier occurs——Fured Steam Energy Saving
