As can be seen from the reaction formula, ①C6H6+（15/2）O2 = 6CO2+3H2O 1 7.5 6 3 0.03 0.225 0.18 0.09 ② CO +0.5 O2= CO2 1 0.5 1 0.036 0.018 0.036 ③ CH4 + 2O2 = CO2 + 2H2O 1 2 1 2 0.27 0.54 0.27 0.54 ④ H2 + 0.5 O2 = H2O 1 0.5 1 0.547 0.2735 0.547 ⑤ CO2 zero point zero four ⑥ O2 zero point zero zero four ⑦ N2 zero point zero seven three five The amount of CO2 generated after the reaction=①+②+③+④+⑤=0.18+0.036+0.27+0.04=0.526 The amount of oxygen required for the combustion process=①+②+③+④ - ⑥=0.225+0.018+0.54+0.2735-0.004=1.0525 1. If the excess air coefficient is taken as 1.4, then the required air volume is 1.4 × 1.0525÷0.21=7.01 The amount of nitrogen contained in the incoming air=7.01 × 0.79=6.22 The remaining amount of oxygen entering the air volume=7.01 × 0.21-1.0525=0.245 The components of the flue gas generated after the combustion of coke oven gas are: CO2, O2, N2 H2O The volume of each component is: 0.526 0.245 6.22+0.0735 1.177 Then 1m ³ The amount of flue gas generated by coke oven gas is: 6.22+0.0735+0.526+0.245+1.177=8.232m ³ 2. If the excess air coefficient is taken as 1.2, then the required air volume is 1.2 × 1.0525÷0.21=6.01 The amount of nitrogen contained in the incoming air=6.014 × 0.79=4.751 The remaining oxygen entering the air volume=6.014 × 0.21-1.0525=0.2104 The components of the flue gas generated after the combustion of coke oven gas are: CO2, O2, N2 The volume of each component is: 0.526 0.2104 4.751+0.073 Then 1m ³ The amount of flue gas generated by the coke oven gas is 4.751+0.0735+0.526+0.2104=5.56m ³ 0 N8 T: f3 B( w
