Reactor and method for gasifying and/or melting materials

摘要

A reactor used for gasifying and/or melting feed materials comprises a feed section, a pyrolysis section, gas feed devices, and a melting and super heating section. A reactor comprises a feed section (1) having an opening (2) for the feed materials; a pyrolysis section (8) connected to the preceding section to expand the cross-section so that a debris cone (9) of the feed materials is formed; gas feed devices (10) which open out into the plane of the expanded cross-section in the pyrolysis section and feed hot gases to the debris cone; a melting and super heating section (14) connected to the pyrolysis section; upper feeding devices (15) for introducing an energy-rich medium into the melting and super heating section; a reaction section (20) connected to the melting and super heating section and containing gas suction devices (21) for removing excess gases; a hearth (25) with a tap (27) for collecting and deviating metal melts and slag melts; and lower feeding devices for introducing an energy-rich medium to prevent solidification of the melts. An independent claim is also included for a process for carrying out gasifying and/or melting of feed materials. Preferred Features: A pre-tempering section (5) is arranged between the feed section and the pyrolysis section and has double walls to create a hollow chamber (6) into which a heat transfer medium is fed.
