摘要:
An apparatus for the gasification of coal or other carbonaceous material is provided for operation at an elevated pressure of at least 30 psia, preferably, between 30 psia and 150 psia. Coal or other carbonaceous material passes downwards through two interconnected sections of a gasifier. In the upper section the coal is dried and partially devolatalized and so converted into a char before it passes into the lower section where it is converted, by reaction with steam and air, into ash and a gaseous mixture of carbon monoxide, hydrogen, carbon dioxide, methane, ethane, ethylene, hydrogen sulphide, carbonyl sulphide and small amounts of ammonia and phenols. The coal, ultimately converted to ash, exits the gasifier through a flanged semi-spherical containment section that has an integrated rotating grate, which collects and disposes of the ash and through which pass the air and steam used as reactants in the gasifier.
