Boiler Blowdown Control | Eurotherm by Schneider Electric

As steam loads vary, the rate of feedwater changes and so does the rate of blowdown. On the other hand, excessive blowdown leads to inefficient running of the boiler plant, as each blowdown causes heat contained within the expelled water to be lost. The cost of fuel can be directly related to this heat loss.

impurities with the steam will occur, as well as the formation of sludge deposits within the boiler. Continuous blowdown (CBD) refers to the removal of the dissolved solids portion of these impurities. Since steam separates from water in the steam drum, it is reasonable that this is the region where dissolved solids will concentrate.
