DEVICE FOR AFTER-BURNING CLAUS UNIT TAIL GASES Russian patent published in 2010 - IPC C01B17/50 F23G7/06 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and is meant for after-burning tail gases from Claus units. The device for after-burning gases has a vertical cylindrical vessel 9, lined inside with refractory material 10, a furnace chamber 1, a reaction chamber 7, an annular chamber for distributing the gas to undergo after-burning 4, whose top part is fitted with an inlet nozzle 6 and has rows of gas discharge holes in the top 5 and bottom part 11 of the furnace chamber 1. Presence of chamber for distributing the gas to undergo after-burning 4 enables feeding the said gas through the top row of gas discharge holes 5 into the top part of the furnace chamber 1, where this portion is mixed with flue gases from the burner and is heated to burning point of combustible components of the said gas, thus after-burning the said components. Heat from combustion of the components of the gas goes to heating the remaining portion of the gas to undergo after-burning in the bottom part of the furnace chamber 1.

EFFECT: invention reduces fuel consumption, increases reliability and service life.
