Combustion Technology

Global warming is currently one of the most serious environmental challenges in the world. The increase of CO2 in the atmosphere is a dominating factor to global warming .O2 / CO2 combustion technology is a new generation of clean coal power generation technology[1],it can directly capture high concentration of CO2 and make the pollutant resource ,so it is one of the most promising feasible technical to reduce CO2 emissions [2]. Compared with conventional pulverized coal combustion boiler, O2 / CO2 combustion technology can be used to produce a CO2 rich flue gas stream. So physical parameters had a very big change, such as flue gas heat capacity, motion viscosity, prandtl number and so on. Thus they affect the heat transfer characteristics [3] inside the furnace.In order to study the heat transfer characteristics of the furnace; this paper established a dynamic mathematical model for the radiation heat transfer progress of the furnace and adequate for control system design.
