Zusammenfassung:	The utility model provides an energy-saving smashed coal pressure dry-discharged fly-ash gasifier. The gasifier comprises a double-coal-lock communicated feeding device (1) and a furnace body. The gasifier is characterized in that the double-coal-lock communicated feeding device (1) is arranged on the furnace body; a dual-channel static coal distributor (2) is arranged at the upper part of the furnace body; a gasification chamber middle raw gas extracting device (3) is arranged in the middle of the furnace body; a rotary furnace grate (4) is arranged at the lower part of the furnace body; a gasifying agent inlet (5) and an ash discharge opening (6) are formed in the bottom of the furnace body; the gasifying agent inlet (5) is positioned between the rotary furnace grate (4) and the ash discharge opening (6); and the gasifying agent inlet (5) is connected with a gas distributing cylinder (412) in the rotary furnace grate (4). The energy-saving smashed coal pressure dry-discharged fly-ash gasifier has the advantages of low coal dust bring-out quantity and less tar gas liquor.
