Boiler Efficiency: Introduction and Methods of Calculation

Learn MoreUse boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.

Learn MoreThe following are the fuel calculation formulas for saturated steam boiler and superheated steam boiler. For saturated steam boilers. Bj = B (1-q4/100) Bj - Calculate fuel consumption, kg/h B-Fuel consumption, kg/h q4-Boiler machinery incomplete combustion loss,% B = 100Q/(Qdw*η) B-Fuel consumption, kg/h Q-Boiler effective utilization of heat, kj/h

Learn MoreThis method calculates boiler efficiency by using the basic efficiency formula-. η= (Energy output)/ (Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation …
