Abstract

Heat balance calculation was used to evaluate the effect of municipal solid waste (MSW) drying on the heat recovery of MSW incineration. Heat recovery efficiency and steam production rate were compared when hot air from air preheater, exhaust flue gas and steam were chosen as media to dry MSW. The calculation results showed that MSW drying always enhances heat recovery by promoting effective steam production. When air preheater was arranged to be heated by flue gas in the heat exchanger network and exhaust flue gas after the air preheater was used as drying medium, heat recovery efficiency and steam production rate gained the highest values, but at the same time flue the g
