METHOD OF BURNING COMBUSTIBLE SHALE IN BOILER WITH CIRCULATING FLUIDIZED BED Russian patent published in 2008 - IPC F23C10/14

Abstract RU 2321799 C1

FIELD: combustion.

SUBSTANCE: method comprises supplying primary air to the furnace with a velocity of at least 2.5 m/s, which provides fluidizing in the bottom section of the furnace, and supplying the primary and secondary oxygen-containing gases to the furnace so that the rate of fluidizing in the bottom section of the furnace under the grate is less than 70% of the fluidizing rate in the top section of the furnace.

EFFECT: enhanced combustion efficiency.
