During a test on a coal-fired steam generator, the following data were obtained: Ultimate analysis of coal: carbon 80.5%, hydrogen 4.6%, oxygen 5.0%, nitrogen 1.1%, sulphur 1.5% and ash 7.3%. Data on the refuse from ash pit: ash content 96% and carbon 4%. Orsat analysis of flue gas: CO, 16.4%, O, 2.3%, CO 0.4% and N2 80.9%. Calculate the following: (a) The weight of dry gaseous products formed per 100 kg of coal fired (b) The percent excess air supplied for the combustion
