SOLID FUEL GASIFIER Russian patent published in 2018 - IPC C10J3/20 F23G5/27 

FIELD: municipal engineering.

SUBSTANCE: present invention relates to a utility system and small power engineering, it can be used for the destruction of solid domestic waste (SDW) and the production of clean fuel gas by the use of a gasifier. Declared result is provided by the constructive performance of the gasifier of solid fuel, which includes a horizontally installed thermal furnace with a built-in plate feeder with plates of gray cast iron with a number of openings for the fluidized bed of fuel, a sealed hopper for collecting ash and waste processing, in the front part is provided with a gas burner with a double cover with a horizontal partition for the heat exchanger located around the gasifier wall, the gasifier and the heat exchanger being in the form of a cone with a baffle sheet, and the cast iron plate of the feeder, having holes for the fluidized bed, is constantly blown by the primary air through the sealed box, the throttle and the fan, thus ensuring a temperature regime on the feeder plate not exceeding 460 °C.

EFFECT: technical result of the invention consists in the production of a pure combustible gas containing methane, ethane, hydrogen, nitrogen and complex C_nH_n with a higher calorific value; in eliminating the need for heat treatment of waste and packaging; in the implementation of a one-time gas withdrawal and the use of a simplified gas purification scheme.
