英文摘要：

The principle of pyrolysis and gasification of waste is introduced, the pyrolysis experiment of medical waste in an external heated fixed-bed is carried out, and the pyrolysis products are sampied and monitored. The technological process of the external heated fixed-bed reactor in treating medical waste is presented. The solutions for problems, such as the shape of pyrolysis gasifier with external heated fixed-bed, sealing, material fragmentation, heat transfer, gasification and treatment of tar and flue gas etc., are discussed.
