METHOD OF SOLID FUEL GASIFICATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C10J3/06 C10J3/46 F23B40/02 

FIELD: waste processing and recycling.

SUBSTANCE: invention relates to recycling of industrial and household wastes by their processing. Method comprises continuous feed of a solid fuel into a shaft onto its combustion grate to make on it from the top to the bottom a distribution of the solid fuel, herewith the continuous feed of the solid fuel into the shaft onto its grate is performed with the solid fuel being uniformly distributed within the volume of the shaft starting from the grate and upward to the place of its loading. At the bottom of the shaft in the area of the producer gas outlet an afterburning zone is formed of the slag and ash passed through the grate. Producer gas is removed in the common flow of the producer gas removal from the shaft, herewith onto the grate an active layer of slag and ash is formed, the activity of which and its level is controlled by the position in the shaft of the high-temperature zone in the solid fuel and the rate of passage of slag and ash downward the shaft into the zone of their afterburning. Preliminary the grate is arranged in the shaft horizontally, and its gear wheels are forcedly rotated in the same direction or in different ones while activating the adjoining layer of slag and ash.

EFFECT: technical result is gasification of full volume of the processed solid fuel and effective control over the process of reverse gasification.
