Boiler Efficiency: Introduction and Methods of Calculation

Feb 14, 2019 · Determine minimum required power Once the total amount of steam is known, it is very simple to determine boiler power. Simply divide the total amount of steam required by either 15.9 kg/boiler hp or 35 lbs/boiler hp (depending on units used). This will calculate the minimum required power to supply the system.

How do you calculate GPM?

This 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 of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where,
