Many customers concern about the boiler price, the cost of the boiler and how to calculate boiler fuel consumption when they want to purchase a boiler. For the calculation of boiler fuel consumption, firstly, determine the specifications and boiler steam production, and the actual enthalpy increment of the boiler is calculated from the steam pressure and steam production. Secondly, the required heat is calculated according to the efficiency of the boiler ( Fuel heat), and calorific value of fuel (per kilogram of fuel can produce heat), that can calculate the required fuel.


ZBG industrial boilers can burn oil, gas, biomass, coal, etc., so fuels are the essential point determining its operating cost. Some clients prefer coal fuel for boilers because there are cheap and rich coal resource in their countries, like in India, Indonesia, Vietnam, etc. Some clients tend to purchase natural gas fired boiler even a little expensive than other fuels because of the government policy. Anyway, you can choose whatever depend the actual requirement and we can meet your need.


Take the 10 ton gas fired boiler for example, we will introduce how to calculate the fuel consumption of the boiler. 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. Moreover, the formula for calculating the hourly gas consumption of a 10 ton gas boiler is: Gas consumption of gas boiler (hourly) = gas boiler power * time / fuel calorific value / gas boiler heat value utilization. The calorific value of the fuel is calculated according to 35.53 MJ/Nm3, then the gas consumption of the 10 ton boiler hour = 7MW*3600s/35.53MJ/Nm3/90%=788m3/h, If the calculation is carried out for 8 hours per day, then the 10 ton gas fired boiler consumes 6304 cubic meters of natural gas per day.
