The Feasibility Analysis of Applying SCR Technology to Regenerative Combustion System

Abstract:

The regenerative combustion technology has been widely used in the recovery of flue gas waste heat, but the denitration is not considered. This article is based on the comprehensive application of the Selective Catalytic Reduction(SCR) technology and the regenerative combustion technology to recycling waste heat and removing NOx from flue gas. In many industrial heating processes, the temperature of flue gas falls from above 1000°C to the ambient temperature (50°C-100°C) along regenerators, while the temperature window of most catalysts ranges from 200°C to 450°C, meanwhile catalysts and regenerative cells are porous mediums, so the regenerative cells that hold a temperature range for catalytic reactions can be replaced by catalysts, and the waste heat of flue gas can be recovered and the nitrogen oxides can be removed simultaneously.
