Beschreibung
Zusammenfassung:	The invention provides an energy-saving crushed coal pressurization and dry ash discharge gasifier. The gasifier comprises a feeding device (1) for communicating two coal locks and a gasifier body and is characterized in that the feeding device (1) for communicating two coal locks is arranged above the gasifier body; a two-channel static coal distributor (2) is arranged at the upper part of the gasifier body; a device (3) for guiding raw gas out from the middle part of a gasifying chamber is arranged at the middle part of the gasifier body; a rotary furnace grate (4) is arranged at the lower part of the gasifier body; a gasifying agent inlet (5) and an ash discharge outlet (6) are formed in the bottom of the gasifier body; the gasifying agent inlet (5) is formed between the rotary furnace grate (4) and the ash discharge outlet (6); the gasifying agent inlet (5) is connected with a gas distribution tube (412) in the rotary furnace grate (4). The gasifier has the advantages of small coat dust bring-out amount and small amount of tar-containing gas water.
