Steam & Condensate System Improvements
Differential Pressure: The difference in pressure between two (2) points, for example, the difference in pressure between the steam header (manifold) and condensate header (manifold) in a dryer section. Flashing: The process of condensate changing to steam when pressure on the condensate is reduced. The
