Abstract
Currently, the flue gas heat recovery rate is very low in China. But flue gas can contain a large amount of waste heat according to the heat balance of the boiler. In the meantime, flue gas heat loss also dominates different kinds of heat losses for a boiler. Therefore, it is necessary to reduce the flue gas temperature and recover sensible and latent heat for district heating purpose. This paper discusses the application mode of a flue gas scrubber for a combined heat and power (CHP) plant, calculate the flue gas recovery rate using absorption heat pumps and analyse the feasibility for a real case study in China. The results show that the maximum heat recovery rate is about 8% if the flue gas can be cooled down to 30°C, and the payback time for the flue gas scrubber is around 5 years.
