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
Nov 16, 2020 · The Formula Used to Identify Required System Volume. In part 1 of this series, we looked at the location of a hydronic heating system buffer tank. The system volume is important. We want a boiler to operate for a minimum amount of time when at low fire. While it is firing, the boiler is putting some amount of BTUs into the water.Learn More

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.Learn More
High-pressure boilers (i.e., those used in industrial and cogeneration applications) are excluded, while residential boilers (i.e., those with a capacity less than 300,000 Btu/h) and small commercial boilers (above 300,000 Btu/h and at or below 2,500,000 Btu/h) are covered by the ENERGY STAR program.Learn More
