Boiler Room Talk; Blowdown Automation Justification

Minimize Boiler Blowdown Minimizing your blowdown rate can substantially reduce energy losses, as the temperature of the blown-down liquid is the same as that of the steam generated in the boiler. Minimizing blowdown will also reduce makeup water and chemical treatment costs. As water evaporates in the boiler steam drum, solids present in the

Saving Boiler Fuel - Veolia

2015-11-3 · The overall boiler efficiency in turning fuel into steam would increase from 70% to 70.8%. The maximum efficiency possible out of the boiler if the blowdown requirements were 0 gpm, which is impossible, and all other parameters are left the same, is 71%. With natural gas prices at $7.00/MCF, this equates to $129,500/year

Purpose of Carrying out Blowdown in a Boiler - ME

Blowdown is necessary to control the level of concentration of the solids, and this is achieved by the process of 'blowing down,' where a certain volume of water is blown off and is automatically replaced by feed water thus maintaining the optimum level of total dissolved solids (TDS) in the boiler water.
