FIELD: machine building.SUBSTANCE: gasifier of solid domestic waste and soild fuel is made as a vertical shaft furnace inside which the following units are set sequentially from top to bottom: zones of drying, pyrolysis and combustion of solid domestic waste and solid fuel. The upper furnace part is equipped by a loading device and a branch pipe to take off product-gas, the lower part is equipped by a branch pipe to supply gasifying agent and a device to accumulate and remove solid processing products - ash. Sections being the component parts of the furnace are installed between its lower and upper parts. Thermal accumulating elements are set in the inner through cavities of the sections, one or more sections can rotate in respect to the upper and lower parts of the shaft furnace around its vertical axis. On the outer side there provided is a housing around the shaft furnace in the zone of the rotating sections, together with the casing it forms an annular closed cavity into which the gasifying agent is pumped and from which the gasifying agent is fed into the gasifier inside through annular gaps between the rotating sections and channels in the lower part of the gasifier.EFFECT: provision for combustion uniformity.3 cl, 3 dwg |
