Prediction of heat recovery characteristics of oxyfuel combustion boiler using CFD

Abstract

Oxyfuel combustion is one of the promising technologies to reduce CO 2 emission from pulverized coal fired power plant. In order to apply this technology to the commercial boiler, it is important to predict the boiler performance (especially heat recovery characteristics) in Oxyfuel combustion condition. In this study, prediction of heat recovery characteristics of Oxyfuel combustion boiler using CFD was conducted. As a result, it was shown that the same boiler performance can be achieved in Oxyfuel combustion mode as that in Air combustion mode. © Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg 2012.
