thermos ceramic mugs What is the excess air coefficient?

thermos Ceramic mugs


In the actual combustion process, in order to ensure complete combustion of the fuel, supplied air volume than theoretical

air amount.A part of this air is excess air.The actual air supply and the theory of air consumption ratio, called the

excess air coefficient, α representation.Using the expression, it can be written as:

Alpha = actual air consumption / theoretical air amount of =V /V

Kiln should be according to the requirement of the product, the atmosphere of the nature of the fuel, sintering temperature

and other factors to determine the size of the excess air coefficient.Alpha value too large, too much cold air into the

kiln, that the combustion temperature is reduced; the a value is too small, incomplete combustion, fuel calorific value can

not give full play to.Therefore, the reasonable control of the surplus air coefficient is an important content of kiln

operation.
