### PROCEDURE FOR DETERMINING THE THEORETICAL

2014-7-24 · gases which are emitted by the boiler is a function of the firing rate and associated theoretical air requirements and excess air used in the combustion process. The more excess air used, the larger the volume of exhaust gases for a given firing rate and the lower the exit gas temperature. The volume rate of flow of the exhaust gas can
