Calculating Boiler Chemical Requirements – Water Technology …

26/6/2017 · The equivalent weight of NaOH is 40, so 0.20 epm X 40 = 8 ppm caustic soda (50%) required. Dividing 8 ppm by 120 gives 0.067 lbs of 50% caustic soda per 1000 gallons of feedwater is required to produce 400 ppm total alkalinity as CaCO3 in the boiler.

Boiler Efficiency

58 CHAPTER 4 pp. 15-17). It is not sufficient to convert energy quantities into the same units, for example BTU to joules or calories to kilowatthours. The units must also be of the same energy form. It is not possible, for example, to cancel out chemical BTU and

Boiler Efficiency

Boiler efficiency may be indicated by Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses
