Steam and Condensate - A basic overview of a steam system

• Shoreside high pressure systems experienced failures from localized caustic concentrations in 1930's and 1940's – Excess hydrate alkalinity led to metal damage in the form of caustic embrittlement (cracking) or gouging • New boiler water treatment was developed using the alkalinity derived from phosphate alone, eliminating sodium hydroxide

Reasons why the condensate- or boiler-feed pump is

Jun 25, 2014 · The boiler pressure is too high. The condensate pump's job is to put the returning condensate back into the boiler. To do this, the pump has to produce a pressure that's higher than the boiler's operating pressure. As a rule of thumb, if the boiler operates at 50 psi or less, the pump should discharge at the boiler's operating pressure, plus
