Gross thermal output is the total thermal output of the CHP system. Total System Efficiency. The total system efficiency ( o) of a CHP system is the sum of the net useful electric output (W E) and net useful thermal output (Q TH) divided by the total fuel energy input ### Steam Calculators: Boiler Calculator - Energy

Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 94850 = 109509 + 691 - 15349 ] Step 5: Determine Fuel Energy Fuel Energy = Boiler Energy / Combustion Efficiency ### AFUE Savings Calculator for Furnaces and Boilers

The AFUE Savings Calculator is designed to help you compare the heating costs of furnaces boilers and heat pumps with different efficiency ratings (expressed in AFUE or HSPF) and fuel types. The calculator estimates your heating cost savings over a one five ten and fifteen year period. ### Steam Calculators: Boiler Calculator - Energy

Blowdown Energy Flow = Specific Enthalpy * Mass Flow [ Blowdown Energy Flow = 3708 = 461.2 btu/lbm * 7.6 klb/hr] Step 4: Determine Boiler Energy. Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 95977 = 115903 + 3708 - ### Steam Calculators: Boiler Calculator - Energy

Blowdown Energy Flow = Specific Enthalpy * Mass Flow [ Blowdown Energy Flow = 4943 = 475.9 btu/lbm * 9.8 klb/hr] Step 4: Determine Boiler Energy. Boiler Energy = Steam Energy Flow + Blowdown Energy Flow - Feedwater Energy Flow [ Boiler Energy (Flow) = 140189 = 158859 + 4943 - ### AFUE Savings Calculator for Furnaces and Boilers
