Heat Transfer Characteristics of O₂/CO₂ Pulverized Coal Boiler Furnace

Abstract:

Global warming is currently one of the most serious environmental challenges in the world. The increase of CO₂in 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 CO₂rich 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.
