The heat transfer character of oxy-fired CFB boiler was studied, and a model of dense zone that considering the combustion and heat transfer is suggested. Through the model, heat transfer coefficient and its impact parameters in dense zone are studied. Some research are done with 30%, 50%,70% O2 conditions, and it was found that the heat(More)
The influence of gases radiation on heat transfer coefficient was considered, and a model of heat transfer in oxy-fired CFB was set up. The model showed that the heat transfer coefficient was not changed greatly in oxy-fuel combustion, because the heat transfer was dominated by solids effects, which did not depend on the gas composition. Take a 440t/h CFB(More)
