METHOD AND APPARATUS FOR GASIFICATION OF CARBONACEOUS FEEDSTOCK Russian patent published in 2020 - IPC C10J3/00 C10J3/20 F23G5/27 

FIELD: technological processes.

SUBSTANCE: invention relates to installation and method of gasification of solid types of carbon-containing fuel. Plant includes a reactor comprising external and internal walls, in the space between which gas-permeable refractory material is located, wherein the inner walls form a downwardly expanding shaft, a loading device installed in the upper part of the shaft, and an unloading device installed in the lower part of the shaft. One of the side walls of the shaft has a hole for removal of gaseous drying products, located in its upper part of the shaft, the first hole for discharge of exhausted combustible gases and the first nozzle located below the hole for removal of drying products, note here that said outlet for drying products is communicated with first nozzle via first channel passing through refractory material. Other side wall of the shaft has a hole for discharge of gaseous pyrolysis products, located below the hole for removal of drying products, second hole for discharge of combustible gases and second nozzle located below pyrolysis products discharge hole, note here that said outlet for pyrolysis products is communicated with second nozzle via second channel extending through refractory material. In reactor also there is upper tuyere located above holes for removal of combustible gases and interconnected by end with shaft, the first middle tuyere, the end of which is located in the first channel coaxially to the first nozzle, the second middle tuyere, the end of which is located in the second channel coaxially to the second nozzle, and the lower tuyere located below the holes for removal of combustible gases and interconnected with the end with the shaft.

EFFECT: invention simplifies the design of the plant and the gasification process with the possibility of using carbon-containing material without limitation on the morphological and fractional composition, intensification of the gasification process, higher efficiency and service life of the plant, as well as low temperature of the outlet combustible gas and production of combustible gas free from volatile resinous compounds.
