SOLID FUEL GASIFIER Russian patent published in 2021 - IPC F23G5/27 C10J3/20 

FIELD: energy and chemical industry.

SUBSTANCE: invention relates to the field of energy and chemical industry, in particular to installations for high-temperature partial gasification of carbon-containing materials to obtain carbonizate. The solid fuel gasifier includes a housing equipped with a water jacket for liquid cooling, a solid fuel loading device, a blast air supply device, a synthesis gas outlet and a carbonizate unloading device. The device for supplying blast air is located in the fuel layer along the entire section of the body above the combustion front and is made in the form of a lattice from a corner facing upward, and the inlets of blast air are located along the perimeter of the body. Below the reduction zone in the carbonizate layer, a cooler is mounted, made in the form of a tubular heat exchanger with a cooling agent, the tubes of which are arranged in rows one above the other with staggered displacement. The device for unloading carbonizate from the body is made in the form of a sluice, consisting of two gates, each of which is formed by two parallel grids, the upper one of which is fixed, and the lower one is movable, the synthesis gas outlet device is made in the form of a lattice from a corner facing upward, whose cavities are connected to the outlet gas manifold.

EFFECT: increasing the efficiency of gasification by ensuring a continuous process.
