Theoretical Air - an overview | ScienceDirect Topics

The theoretical air requirement for complete combustion of a unit mass of a fuel, m th, is an important parameter.It is known as the stoichiometric air requirement. Its calculation is shown in Eq. 2.34.For an air-blown gasifier operating, the amount of air required, M a, for gasification of unit mass of biomass is found by multiplying it by another parameter ER:

2  · This above mentioned analysis is called coal analysis for combustion. Before efficient combustion can take place, several basic requirements must be fulfilled, most important of them are, The combustion must be done with sufficient oxygen. There must be sufficient turbulence to promote throughout mixing of combustible and oxygen.

Stoichiometric Air or Theoretical Air Quantity

Coal is the most widely used fuel source used to produce Electricity. Air provides the necessary Oxygen for burning coal. It is the chemical reaction between Carbon in coal and the Oxygen in the air that produces the heat energy. The most important requirement to burn coal is the correct quantity of air. The method of calculating the air quantity is explained in this article. The Heating value
