How to calculate the gas consumption of a gas steam boiler

We use a 1 ton gas-fired steam boiler as the base to calculate the method for calculating the gas consumption of the boiler. First, factors affecting the gas consumption of the boiler 1. Boiler heating area Generally speaking, the larger the heating area is occupied in the whole boiler, the more heat is transferred to the boiler by the fuel

How to calculate the gas consumption of a gas steam boiler

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷(Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h, here we take 4 tons of natural gas boilers for example, then the boiler gas consumption per hour need only about 297 cubic meters.
