PYROLYSIS AND GASIFICATION COMBINED DEVICE OF CIRCULATING FLUIDIZED BED

WIPO Patent Application WO/2016/145924

A1

Disclosed is a pyrolysis and gasification combined device of a circulating fluidized bed. The pyrolysis gasification combined device has an H shape in a bilaterally symmetrical arrangement with a boiler furnace (9) being the symmetrical line or the centre of symmetry. A side coal bunker (12) is connected to a pyrolysis and gasification furnace (1) and a back feed leg of a boiler back feeder (8) respectively. The boiler back feeder (8) is connected to the boiler furnace (9) via the back feed leg thereof. The side coal bunker (12) is arranged away from the boiler furnace (9). A cyclone separator (10) is arranged close to the boiler furnace (9). The pyrolysis and gasification furnace (1) is arranged between the side coal bunker (12) and the boiler furnace (9). A first stage separator (2), a second stage separator (3), a material returning device (5), a first stage material returning device (6) and a second stage material returning device (7) are arranged between the pyrolysis and gasification furnace (1) and the boiler furnace (9). The present pyrolysis and gasification combined device of a circulating fluidized bed employs a combined method where a H-shaped arrangement is added to the pyrolysis and gasification furnaces (1) arranged on both sides. Both the back feed leg of the boiler back feeder (8) and the pyrolysis and gasification furnace (1) of the circulating fluidized bed are combined to feed materials by arranging the side coal bunker (12), so that the connection devices between the boiler, the side coal bunker (12) and the pyrolysis and gasification furnace (1) are more simple and reliable.
