Oxy-Fuel Combustion of Coke Oven Gas under Distributed Combustion Conditions
AbstractThis study concentrates on oxy-fuel combustion of coke oven gas under distributed combustion conditions. Distributed combustion technique is a novel combustion method to provide more uniform thermal field and to mitigate NOX emission. In this study, coke oven gas has been burned for varying oxidizer concentrations such as 100 % O2, 75 O2 % - 25 CO2 and 50 % O2 – 50 % CO2 simulating hot product gas recirculation. It has been concluded that the distributed combustion conditions provided far more uniform thermal field that resulted in much reduced NOx emissions under oxy-fuel combustion conditions. The results showed that enhanced thermal field uniformity and much reduced NOx emissions can be achieved by burning coke oven gas under distributed combustion conditions.
