Nov 23, 2021 · Gas boiler. The gas boiler is auxiliary equipment to supply the heat power. The relationship between the consumed volume of natural gas in the gas boiler (V NG,GB, m 3 /s) and the heat provided to the user (Q GB, kW) can be calculated as follows. (29) V NG, G B = Q GB η GB · Q L. where η GB is the heat efficiency of the gas boiler.Get Price
