<p>A process is disclosed for allothermic gasification of coal under pressure with water vapour in a gas generator containing heat-exchange tubes for the heat transfer medium. The hot heat transfer medium that enters the gas generator by the heat-exchange tubes is first introduced in the gasification zone, then in the pyrolysis zone. The coal to be gasified flows counter-currently through the gaz generator, so that the current of cooled heat tansfer medium is used for heating and pyrolyzing the coal, whereas the heat for gasification is taken from the current of the still hot heat transfer medium. Gas generators vertically or horizontally arranged with fitting designs are used for implementation of the process.</p> |
