INJECTOR UNIT FOR COAL HYDROGENATION GASIFIER AND METHOD FOR OPERATING THE INJECTOR UNIT

摘要

PROBLEM TO BE SOLVED: To provide an improved injector unit to be used in a coal hydrogenation gasifier intended to directly produce a hydrocarbon-based gas by hydrogenating coal with high-temperature hydrogen. SOLUTION: This injector unit has such a scheme that a pulverized coal feed nozzle 4 is mounted at the center of the tip panel board 2 of a pressure vessel 3, and a plurality of hydrogen/oxygen burners 50 are detachably set up concentrically about the pulverized coal feed nozzle 4 so as to enable a high-temperature gas from the burner nozzle ports to collide with pulverized coal from the feed nozzle 4.
