### BOILER EFFICIENCY GUIDE - Cleaver-Broo

boiler equipment requires review of boiler type, feature and benefit comparison, maintenance requirements and fuel usage requirements. Of these evaluation criteria, a key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler

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.
