Boiler Blowdown Control | Eurotherm by Schneider

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.
