METHOD OF CONDENSED FUEL GASIFICATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC F23G5/27 

FIELD: heating, burning.

SUBSTANCE: invention relates to thermal processing of condensed fuels. Method of carbon-bearing condensed fuels gasification implies passing oxygen-containing gasifying agent through the fuel layer in counterflow, maintaining gasification process in the fuel layer. Value of the maximal temperature in the gasifier is restricted by the prescribed limits, solid and gaseous processing products are removed from the gasifier. Additionally, fuel consumption values are aligned according to the gasifier cross section, the fuel layer is broken and zone of maximal temperature is kept below the above breakdown. The device for carbon-bearing condensed fuels gasification comprises a shaft-type overload gasifier fitted with means for loading the fuel into the gasifier working zone, means for supplying oxygen-containing gasifying agent, means for removing produced gas, means for taking out solid processing products from the gasifier working zone as well as means for controlling temperature in the working zone. Additionally, the device comprises means for aligning fuel consumption values according to the cross section of the gasifier working zone with its outlet located at the distance L_o=(0.2-0.75)L_wz from the lower boundary of the gasifier working zone, where L_wz stands for the length of the gasifier working zone.

EFFECT: increasing uniformity of distributing temperatures in the fuel layer and increasing the process controllability.
