Power - Burner Model

The Burner model simulates a base or swing loaded burner.
There are three calculation types for the Burner model. For base loaded burner, the model calculates the amount of air required for a given amount of fuel and given flue gas conditions. If swing loaded, the burner calculates either the amount of fuel necessary to produce the given amount of flue gas, or the amount of fuel and excess air required at the given combustion air and flue gas conditions.

Method&Equations

   Fuel + p O2 -> Fuel gas
where:
   p – is the mass proportion of O2 to combust one mass unit of fuel
Option 1
    Fuel flow is given
    In this case the burner is considered base loaded.
    Combustion air in = 5* p * Fuel in
    Excess air in = Excess O2 * Combustion air in or Excess air in is adjusted to take over the heat generated from the combustion in order to meet the Flue gas outlet temperature.
    Flue gas = Fuel in + Combustion air in + Excess air in
Option 2
    Combustion air flow is given
    In this case the burner is considered base loaded.
    Fuel in = Combustion air in / 5 / p
    Excess air in = Excess O2 * Combustion air in or Excess air in is adjusted to take over the heat generated from the combustion in order to meet the Flue gas outlet temperature.
    Flue gas = Fuel in + Combustion air in + Excess air in
Option 3
    Flue gas flow is given
    In this case the burner is considered base loaded.
    Flue gas = Fuel in + Combustion air in + Excess air in
    Using the previous relations each input flow can be determined.

Warnings

No Excess Air Required.

Combustion Air flow is 0, calculations go on with 100 lbs/hr.
