Abstract：To promote clean and efficient conversion of lump coal in China,typical coal pyrolysis technologies and reactor characteristics at home and abroad were summarized from the aspects of reactor design mechanism,structure characteristics,application scope.The applica-tion of vertical pyrolysis furnaces and rotary pyrolyzers on lump coal pyrolysis was discussed.The results showed that the lump coal pyroly-sis processes with solid heat carrier had the advantages of high reaction rate and pyro-gas calorific value,little dust entrainment.Supported by optimized rotary reaction equipment,the processes were easy to realize industrial large-scale production.Carrying on the general prob-lem of dust removal from high temperature pyro-gas,some solutions were proposed,such as to develop high temperature electrostatic pre-cipitators,compound separation system like cyclone-granular moving bed filter and cyclone-ceramic filter.
