I am doing coal combustion simulation through blast furnace Tuyere and wish to see impact of Natural gas or coke oven gas injection on pulverized coal combustion. I have separate inlets for pulverized coal and gaseous fuel. As I am doing coal combustion I am having coal volatile-air mixture as default mixture. I am able to add methane-air mixture in material stream but cannot assign it as fluid to cell zones of gaseous fuel. I also tried to add CH4 and other gaseous components to coal volatile - air mixture and change first reaction with CH4 and O2 as separate reacting species is it right doing so?
