Mar 24, 2020 · The indirect efficiency of a boiler can be calculated by figuring out losses taking place in a boiler and then deducting the sum from . Some of the factors considered for indirect efficiency include stack losses, radiation losses, blowdown losses, etc. Boiler indirect Efficiency = 100 – (i +ii + iii + iv + v + vi + vii)

Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization. For example, we operate 1 ton gas boiler for 1 hour (full load). The boiler output is 600,000 kcal (fixed value), the natural gas calorific value is 36.22 MJ/Nm3 (fixed value), and the thermal efficiency is 92% (non-fixed value). According to the actual situation of the boiler, the calculation is carried out.
