  • 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)

  • How to Calculate Boiler Steam Flows | Hunker

    Modern power plants have huge boilers to feed turbine generators. Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow.

  • Boiler Ratings | Spirax Sarco

    The 'from and at' rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create 'from and at 100°C',at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler. Shell boilers are often operated
