Why return condensate to the boiler? - Plant Services

2010-4-21 · One must understand the factors that prevent the condensate from being returned to the boiler if the plant wants to establish corrective methods. The first is selecting condensate pumps having the proper net positive suction head (NPSH). A number of condensate pumps handle only condensate temperatures of less than 200ºF (93°C).

Blowdown Heat Recovery | CleanBoiler.org

Blowdown Heat Recovery Introduction. All steam boilers must blowndown to reduce the amount of TDS in the boiler water. See Blowdown However, along with the solids, boiler chemicals and thermal energy is lost; blowdown heat recovery systems cannot recover the chemicals, but they do recover up to 90% of the heat energy that would otherwise be lost down the drain.

Heat Pipe Heat Exchangers for Boiler Flue Heat

This chapter discusses heat pipe heat exchangers for boiler flue heat recovery. A boiler as a cross flow heat exchanger with well mixed heating fluid is at uniform temperature; it follows that however efficient the heat exchange surfaces may be the products of combustion can never be cooled below the maximum temperature of the fluid and in practice, the exit gases are well above the fluid
