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 = (h g - h f) m (1) where . W = boiler capacity (Btu
