GASIFICATION OF CARBON-BEARING SOLID FUELS Russian patent published in 2014 - IPC C10J3/46 F23C3/00 F23G5/27 

FIELD: process engineering.

SUBSTANCE: invention relates to gasification of solid carbon-bearing combustibles, i.e. lignite and coal, shale oil and peat. Gasification comprises heating and pyrolysis of solid carbon fuel fed into bath with fused melt of sealed electrode kiln at forcing gasifying agents through fused slag with solid carbon fuel. Besides, electric current is passed by electric circuit including electrodes fed into kiln bath and kiln hearth. Synthesis gas, slag and metal alloy is removed from kiln working space. Three-phase current if fed through fused slag with solid carbon fuel, current magnitude being defined in compliance with solid fuel consumption and required power defined by relationship: $$P_a=\frac{G\times w_p}{3600},MW,$$ where G is solid fuel consumption, kg/h, w_p is specific power consumption.

EFFECT: more efficient application of electric power, more stable process.
