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.
