Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · C. Sample Calculation. Assume boiler is operating at 10 cycles of concentration with feedwater at 205 o F. This equates to a dissolved oxygen content of 0.7 ppm or 0.5 cc per liter. Assume a feedwater demand of 500,000 lbs per day. The desired sulfite residual is 30 ppm. 1. For fixation of dissolved oxygen: 0.7 ppm x 10 ppm = 7 ppm

Combustion Air Requirements:The Forgotten Element In

Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.
