Apparatus for gasification of fine-grain coal
An arrangement for pressure gasification of fine-grain coal in which the exit of a reactor is followed by a waste heat boiler for cooling the generated gas. The waste heat boiler has a radiation section and downstream heat exchanger surfaces. The reactor is provided, furthermore, with cooling cubes which are studded and lined with refractory ramming mix. The radiant type heating surfaces are sized so that the gas temperature at the exit of the radiation section is situated below the ash sintering temperature of the coal being used. On gas sides, the radiation section is followed by a pressure vessel accommodating convection type heating surface banks which are swept by the generated gas. The radiation section may be in the form of two gas passages through which the gas flows successively. These gas passages are formed by the tube walls welded between each other in a gas-type manner.
