There are two important factors to recognise with bottom blowdown: Energy content of blowdown. The energy contained in the water being blown down is the liquid enthalpy of water at saturation temperature at boiler pressure. In Example 3.14.1, the boiler pressure is 10 bar g, and from steam tables, hf is 782 kJ/kg.

Blowdown in Boiler Definition Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.
