Steam Traps - Back Pressure and Capacity
A back pressure in a condensate systems will reduce steam trap capacity
Steam trap capacities are reduced if there is a back pressure in the condensate system. A back pressure can be the result of excessive flash steam generation.
Back pressure and reduction in steam trap capacities:
Inlet Pressure | Back Pressure (%) | |||
---|---|---|---|---|
(psig) | (bar) | 25 | 50 | 75 |
5 | 0.35 | 6 | 20 | 38 |
25 | 1.75 | 3 | 12 | 30 |
100 | 6.9 | 0 | 6 | 25 |
200 | 13.8 | 0 | 5 | 23 |
