Before calculating gas boiler fuel consumption, we should first understand which factors can affect fuel consumption,then, according to the gas boiler fuel consumption formula, bring in the required parameter values to calculate boiler fuel consumption.
Gas boiler fuel consumption is mainly affected by two factors: the capacity of gas boilers and the thermal resistance of the heating surface of the boiler. The capacity of the boiler determines the tonnage of the boiler, and the thermal resistance of the heating surface of the gas boiler determines the rated calorific value. These two factors are the key factors affecting the gas consumption of boiler,addition , Various factors such as the quality of the gas fuel,the exhaust gas temperature, boiler tightness, and the operation of the burner.

We need to determine the capacity of the gas boiler, followed by the thermal resistance of the heating surface of the natural gas boiler. According to these two conditions, we can determine the heat loss of the natural gas boiler. By obtaining the heat loss value, the thermal efficiency can be further obtained. The total capacity is multiplied by the parameter to obtain the total heat enthalpy value, and then the total heat enthalpy value of the gas is multiplied by the thermal efficiency. The value obtained is divided by the total heat enthalpy of the medium, which is the total amount of gas we need.
So ,we can get the formula of Gas boiler fuel consumption,it is boiler fuel consumption (hourly) = gas boiler power / boiler rate * time / fuel calorific value / gas boiler heat value utilization
2 ton gas fired boiler
After understanding factors of affecting gas boilers fuel consumption and boiler fuel consumption formula, we can take 2 ton oil gas boiler for example and calculate gas boiler fuel consumption
boiler fuel consumption (hourly) = gas boiler power / boiler rate * time / fuel calorific value / gas boiler heat value utilization=1.4MW*3600s/35.53MJ/Nm3/88%=161m3/h.
So,2 ton gas boiler consumption is 161m3/h
