Engineering and Economic Analysis of Waste to Energy Systems

The overfire secondary air is used to help complete combustion and keep the flue gas tem- perature within working limits. The gas temperature must be maintained between 871°C (1600°F) and 1093°C (2000°F) to obtain proper boiler perfor- mance and to inhibit corrosion of the water tubes of the steam superheater, generator, and economizer.

Boiler Capacity - Engineering ToolBox

Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour. A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour) and can be calculated as. W = (hg - hf) m (1) where. W = boiler capacity (Btu/h, kW)
