SYSTEM FOR CONTINUOUS FUEL FEED TO REACTOR FOR COAL GASIFICATION Russian patent published in 2013 - IPC C10J3/46 C10J3/50 B01J8/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to a device for solid fuel materials feed to a gasification reactor of solid fuel materials, which includes the following: crushing device (2), dust collector (3), storage reservoir (4), at least two sluice feeders (5), one or more connection devices (12) for transportation in a dense flow, feed tank (13), gasification reactor (15), in which crushing device (2) is connected to storage reservoir (4) by means of connection device; with that, dust collector (3) is arranged between crushing device (2) and storage tank (4), which includes pressure rise device (18) that returns transporting gas from feed tank (13) to sluice feeder (5). With that, storage tank (4) is connected to sluice feeders (5) through connection devices, which are made so that they can be moved by gravity or transported in a dense flow, and sluice feeders (5) are connected to feed tank (13) by means of jointly used one or more connection devices (12), which are useful as pipeline (12) for continuous feed for transportation in dense flow. With that, feed tank is connected to gasification reactor through additional fuel pipelines (14). Invention also refers to a method for feed of fine fuel to the coal gasification reactor.

EFFECT: reduction of number of pieces of equipment, height of a building structure, and improving reliability of the device.
