The exhaust gas of a coal combustion process shows the following analysis:
CO2 = 11.3 % O2 = 7.7 %
CO = 1.2 % N2 = 79.8 %
Assume that the coal contains no free water or bound water.
(a) What is the percentage excess O2 supplied?
(b) What is the degree of completion of the C combustion?
(c) What is the ratio C : available H2 in the fuel?
(d) Calculate the kmol exhaust gas formed per kg carbon that burned.
Assume that the nitrogen and sulphur content of the coal are negligible and that no
combustible material is lost in the ash
