Pulverized Coal Fired Steam Boilers - coalboilerchina.com

Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels.

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.
