SOLID FUEL GASIFIER Russian patent published in 2004 - IPC

FIELD: processing of peat, poor-quality coal, wood-working waste, solid domestic garbage, etc. by interaction of fuel with gasifying agent and pyrolysis with production of fuel product-gas, this fuel gas-product may be used for heating of steam and hot-water boilers, in driers as fuel for gas turbines, it may be widely used in power generation/

SUBSTANCE: the solid fuel gasifier has a vertical shaft furnace with zones of drying, pyrolisis and combustion of solid fuel placed in succession, from top to bottom, in it. A charging device and a branch pipe for extraction of product-gas are located in the upper section of the furnace, a branch pipe for supply of the gasifying agent and a device for accumulation and removal of solid processing products - ash are located in the lower section. One or several sections are positioned between the upper and lower parts of the gasifier, they serve as components of the gasifier and have inner through cavities in the center located in the direction of the vertical axis of the gasifier and communicate with the inner cavities of the upper and lower parts, as well as with the inner cavities of the other components of the gasifier. The sections have a housing with a lining, fastened in it are the ends of the thermoaccumulating elements located in the inner cavity of the section. One or several furnace sections are made for rotation relative to the upper and lower parts of the gasifier about its vertical axis.

EFFECT: simplified structure, enhanced reliability and capacity.
