Determining the air excess in the heating of coke furnaces. 1. Adequacy of the chemical analysis

Resumo

The traditional chemical framework for determining the air excess in the heating of coke furnaces is discussed. In determining the air excess, no account is taken of numerous chemical reactions associated with the combustion of the fuel gas in the heating channels. In fact, it is necessary to determine combustion products other than oxygen, carbon monoxide, and carbon dioxide: specifically, hydrogen, methane, nitrogen oxides, and sulfide. The formula for the air excess must therefore be corrected to include the content of those components.
