Abstract. This paper proposes a method for intensifying the flue-gas cleaning from sulfur compounds in order to use it in heat exchangers and to improve environmental and energy efficiency and economic performance of the coal-producing enterprises. Different methods and equipment were considered for beneficial use of flue-gases heat. To ensure operation of such equipment in the mine’s energy complex, it is necessary to use contact heat exchangers. Basing on analysis of peculiar thermophysical processes in the contact heat exchangers, it is recommended to use designs with spray-type devices and centrifugal heat exchangers. The contact heat exchangers of such design have significant resource for intensifying the thermal processes. Different methods are discussed for cleaning the flue gases from sulfur dioxide and feeding them to the contact heat exchangers. An oxide-manganese method was chosen, as it is related to the "dry" method of the flue-gas cleaning. A layout scheme is proposed for devices for flue-gases cleaning from sulfur dioxide and their usage in contact heat exchangers in order to supply heat to the energy unit in the mine’s energy complex. The stages of main chemical reaction of the oxide-manganese method is considered. In order to intensify this reaction, it is proposed to apply pulsation to the flue-gas flows entering the apparatus of their cleaning from sulfur dioxide.

Keywords: contact heat exchangers, sulfur dioxide, manganese oxide, intensification, flow pulsations, flue gases.
