Numerical Study of the Influence of Refractory Thickening on the Reacting Flow and DeNOx Effect in a CO Boiler

Abstract

Performance of a CO boiler has a detrimental influence on the operation and production of related industries. In a previous study, we have presented a numerical study of the influence of refractory thickening on the heat transfer and fluid flow in a CO boiler. In this paper, the influence of refractory thickening on the reacting flow and DeNOx effect in a CO boiler is discussed. It is found that refractory thickening can reduce the temperature and the skin friction in the DeNOx section. Furthermore, NOx formation in the DeNOx section is also alleviated by refractory thickening.
