Heat Loss in Industry: Boiler Performance Analysis

15/8/2020 · Therefore, we will conduct the performance evaluation of a fire tube boiler burning fuel (HHV 9238,55 kcal/kg) through formulas retained from this study. Indirect method is found to be more effective and accurate than the direct method, and the major heat losses are dry combustion gases loss as well as water produced by hydrogen in fuel loss.
