boiler surfaces to the surroundings is taken at an average level of 200 – 300 W/m2 With increasing boiler power, the absolute 35 and relative heat loss q5% becomes lower as the total heat release and the volume of combustion products increase more quickly than the area of exposed boiler surfaces.
Another way to look at the efficiency of both boiler types is this: The HRSG generates an additional 75,000 lb/hr of steam with a fuel input of only 75.6 million Btu/hr (subtract the fuel input at 100,000 lb/hr steam from the unfired case steam generation). The package boiler, on the other hand, requires 84 million MM Btu/hr (111.6-27.56).
