GASIFIER DEVICE HAVING THE SHAPE OF FLATTENED SPHEROID Russian patent published in 2002 - IPC

FIELD: gasification of feed stock material. SUBSTANCE: gasifier device has a gasification chamber having the shape of a spheroid, inlet pipe connection for feed stock material and inlet pipe connections for gaseous oxidizer, a great number of Venturi tubes designed for recirculation, recirculates the working fluid formed by combustion products and the solid particles to the zone of gasification and from it. Each Venturi tube is provided with a high-pressure chamber having an inlet pipe connection for gaseous oxidizer and a great number of ports capable of generation of an air flow having a high flow velocity in the direction to the layer of feed stock material in the zone of gasification. A great number of air guns connected to one or more momentum valves provide for a momentum air flux in the zone of gasification. The inlet pipe connection of gaseous oxidizer to the zone of ash catching provide for control of the connected of carbon in the zone. EFFECT: reduced volume of source material approximately by 90%, reduced harmful effluents to the atmosphere. 20 cl, 6 dwg
