2020-4-15 · The loss of heat transferred to the environment S 4, taking into account heat transfer from the boiler to the environment by convection and radiation, and is calculated from the empirical formula : (24) S 4 = 10 0.36173 − 0.2912 lg Q ˙ u where Q ˙ u is the utilized heat power in the boiler and is determined using heat balance calculations

2011-8-26 · The heat losses are less at higher loads. If we consider the additional boiler duty and the additional fuel input for this additional steam generation, the HRSG comes out a winner hands down. At 50% load, the steam generation is 50,000 lb/hr, and additional boiler duty is 24.9 million Btu/hr compared to the unfired condition.
