Technical Field

The utility model relates to the field of coal feeding devices, in particular to a coal feeding device for preventing coal from blocking a coal conveying pipe of a spiral coal feeder of an Ende furnace.

Background

The Ende pulverized coal gasification technology is developed gradually through multiple technical modifications on the basis of the Windler gasification furnace technology.

Compared with the traditional Winker gasifier, three major improvements are made, namely, the bottom of the gasifier is changed into a cone with a certain shape, the original grate is omitted, and the air distribution nozzle is replaced, so that the problems of slag bonding and deviation of the bottom of the gasifier are solved, and the production capacity of the single gasifier is improved; secondly, a cyclone dust removal returning device is added at the outlet of the producer to reduce the carbon content of the carried-out matters; thirdly, the arrangement of the waste heat boiler is changed, the abrasion of the boiler tube is reduced, and the running time of the waste heat boiler is prolonged.

The Ende furnace generally adopts a spiral coal feeder to convey the fire coal from a coal bin into a hearth for combustion, and because the boiler hearth operates under positive pressure, the fire coal has certain thermal cohesiveness, when the flue gas is in reverse channeling, the fire coal is heated to reach the cohesiveness temperature to generate cohesiveness until a coal conveying pipe is blocked, and the normal conveying of the fire coal is affected.
