Read More2012/7/1 · A boiler uses coal at the rate of 3000 kg/h in producing steam with a specific enthalpy of 2700 kJ/kg from feed water with a specific enthalpy of 280 kJ/kg. The combustion of 1 kg of coal produces 28000 kJ, of which 80% is useful in producing steam.

Read MoreSince 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)

Read More2017/6/23 · h = h f + h fg + c p (T sup – T s) ….. Superheated steam at pressure p and temperature T sup. h f1 = Specific enthalpy of water at a given feed temperature. Then heat gained by the steam from the boiler per unit time = m a x (h – h f1) The equivalent evaporation (m e) from the definition is obtained as: The evaporation rate of the boiler

Read More2015/3/17 · 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.
