Prediction of Combustion Behavior in a Boiler Fired by

To solve this problem some methods have been tested. In this research a mixture of anthracite and coal gas is considered. The purpose of the research is to describe a combustion behavior in a boiler, namely temperature, carbon and volatile matter distributions using CFD. The mixture consists of 4.3 % coal gas and 95.7% anthracite in mass.
