BOILER WITH CIRCULATING FLUIDIZED BED AND METHOD OF MOUNTING THEREOF Russian patent published in 2018 - IPC F23M5/08 F23C10/10 F23J11/00 

FIELD: technological processes; gas industry.

SUBSTANCE: invention relates to a circulating fluidized bed boiler and a method for mounting a fluidized bed boiler. Circulating fluidized bed boiler (10) comprises rectangular furnace (12) that is horizontally bounded by side walls comprising first and second short side walls (14, 14') and the first and second long side walls (16, 16'), set of separators (18, 18') of particles located on the side of each of the first and second long side walls (16, 16'). Each of the particle separators comprises vertical gas outlet (28, 28') for discharging the purified flue gas from the particle separator, convection shaft (20) located on the side of second short side wall (14') of furnace. Convective shaft is horizontally bounded by walls of the convective shaft, comprising first wall (32) of the convective shaft facing the second short side wall (14') of furnace, and system (22) of horizontally passing passageways directly connected to vertical gas outlets (28, 28') of the particle separators to conduct the cleaned flue gas to convective shaft (20). Bypass channel system (22) provides a straight-line gas trajectory that slopes with respect to side walls (14, 14', 16, 16') of furnace (12) from each of vertical gas outlets (28, 28') of separators (18, 18') of the particles to openings (30) in first wall (32) of the convective shaft.

EFFECT: invention is aimed at the constant flow rate of the flue gas.
