METHOD AND INSTALLATION FOR THERMAL PROCESSING OF HIGH-ASH SOLID FUEL Russian patent published in 2008 - IPC C10B49/16 

FIELD: chemistry; fuel.

SUBSTANCE: raw fuel is subjected to crushing and mixed with solid heat-transfer agent. The obtained during the mixing with the solid heat-transfer agent initial gas-vapour mixture, containing water vapour and carbon dioxide are removed from the mixer. After which it is passed to an additional dust precipitation chamber, cooled and sent to the cleaning system and condensation. The gas-vapour mixture, obtained in the pyrolysis reactor, is taken to the dust precipitation chamber, connected to the pyrolysis reactor, cooled and sent to the corresponding cleaning system and condensation. The coking remains obtained from the pyrolysis process are burnt in the air-gushing furnace with the reception of a solid heat-transfer agent, directed to the mixer. Warmth of the crude flue gas is used in the heat exchange device and the waste heat boiler.

EFFECT: increase in the quality of the obtained liquid and gas products, simplification and cheapening the process.
