The 10 ton gas fired boiler has an output of 10 tons per hour, which is also the capacity of the boiler. To calculate the gas consumption of a natural gas boiler, you need to know the heat resistance of the heating surface of the natural gas boiler, the heat value of the natural gas boiler, and the efficiency of a 10-ton boiler.

Flue Gas Waste Heat Boiler Thermal Efficiency Calculation 2017-10-04 17:02:11. Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat loss. The heat efficiency of a flue gas waste heat boiler is the percentage of the

Use 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.
