  • 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)Learn More

  • Boiler Formulas | Johnston Boiler | Top Quality Boiler

    Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.Learn More
