The goal of the gas-fired boiler is to determine the proper heating surface to ensure the proper efficiency and output of the boiler. The flue gas generated during the combustion of gaseous fuel and after combustion has its own characteristics compared with solid fuel. The thermodynamic calculation of the gas steam boiler includes the following points, the calculation of the boiler thermal balance, and the balance of each heat loss. Based on this, the main fuel consumption and thermal efficiency of the boiler are obtained.
The calculation of the heat balance should be carried out at the boiler unit under certain thermal conditions. For gas-fired steam boilers, usually calculated according to the standard next cubic meter of gaseous fuel
