Combustion Calculations For Gas Fuel

Combustion Calculations

Fundamentals of Combustion and its Modeling 

  • Refer to the following useful articles on the basics of combustion and its CFD modeling

Calculation of Mass flow rate of air and fuel

  • In the following table, the mass flow rate of actual air can be calculated based on given fuel composition and excess air conditions
  • Key input and out for combustion calculate
    • Enter Inlet temperature (F), excess air (%), fuel composition of natural gas ( % mole fraction) and the fuel firing rate (10∧6 Btu/hr) of the burner
    • The output is given for the mass flow rate of air and air in pounds per hour (lb/hour), and the enthalpy of flue gases
