Abstract

District heating in China is growing very fast, but the heat production is still and will be mainly based on coal in the near future. Therefore, it is necessary to improve the efficiency of coal-fired heat production; one important way for this is to recover the waste heat in the flue gas. This paper analyzes the influencing factors for flue gas heat recovery and proposes the use of a flue gas scrubber to recover the flue gas in a coal-fired heat-only boiler after desulfurizer. We apply this technology to a heat-only boiler in Dalian city and discuss the feasibility from the perspectives of energy, economy and environmental aspects. The results show that the maximum heat recovery rate is about 7% if the flue gas can be cooled down to 39 ℃, and the payback time of the scrubber system is about 4 years.
