Thermodynamic Design of a Fire­Tube Steam Boiler

Total heat transfer produced by furnace is modeled by the equation Q = (h3−h2) where: Q = Heat transfer rate in KW = Mass flow rate in kg/s h 2 = Water entering boiler at 10 bar and 20 o C h 3 = Enthalpy of Steam exiting boiler at 180 o C

Options for Improving the Efficiency of Heat Recovery Steam Generators …

2021/11/11 · In any heat transfer equipment such as a boiler or Heat Recovery Steam Generator (HRSG), the exit gas temperature determines the amount of energy recovered from the flue gas stream, which is indicative of efficiency. Hence efforts are often made to lower this …

Steam Calculators: Boiler Calculator

2015/3/17 · 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.
