When steam expends its energy, by giving up its heat or by doing work, it condenses back into water (Figure 14.1). This water must be removed from the pathway of the steam so it will not interfere with the function of the steam system. Once removed, the condensate, pure hot water, should be returned to the boiler where it is again heated to produce more steam. Condensate formation in steam distribution line.
