A REVIEW ON FUNDMENTAL RESEARCH OF OXY-COAL COMBUSTION TECHNOLOGY

ABSTRACT
Oxy-fuel combustion is a key technology to realize CO2 capture and storage in coal-fired power boilers in the future. In recent years, there have been extensive studies on it. This review summarizes some key results of fundamental research on oxy-coal combustion. By comparing with traditional coal-fired boiler with air combustion in power station, the typical characteristics of oxy-coal combustion are introduced from four aspects: combustion, heat transfer, pollutant emission, and numerical simulation; so that readers have a relatively comprehensive understanding of fundamental research on oxy-fuel combustion. Furthermore, some scientific issues in future research are summarized. The paper is both academic and popular, providing basic knowledge and academic direction inspiration for scholars or graduate students who are about to engage in oxy-fuel combustion research.
