Issues regarding the calculation of the thermal efficiency of gas boilers
Thread Content
Hello, fellow sea users. I have two gas boilers here, and I’d like to calculate their thermal efficiency. Does anyone know of a convenient tool for such calculations that I could use as a reference? Also, when calculating the enthalpy value, should I use the outlet water or the inlet water temperature of the deaerator?
The thermal efficiency of a boiler refers to the ratio of the heat contained in the steam or hot water produced by the boiler to the total heat, including both physical and chemical heat, associated with the fuel and other materials that enter the boiler at the same time. Therefore, by calculating the ratio of the heat generated per unit time to the calorific value (amount consumed) of the fuel, it is possible to determine the boiler’s approximate thermal efficiency (excluding heat losses). :L:L Personal opinion: L:L:L
It is to calculate the boiler efficiency; therefore, when doing the calculation, the parameters of the deaerator’s feed water to the boiler must be taken into account
It is necessary to check whether the steam used in the deaerator is the steam from the boiler itself
