LATTICE NOZZLE ASSEMBLY, FLUIDIZED-BED REACTOR WITH LATTICE NOZZLE ASSEMBLY AND LATTICE NOZZLE ASSEMBLY APPLICATION Russian patent published in 2017 - IPC F23C10/20 B01J8/44 F27B15/10 

FIELD: electricity-producing industry.

SUBSTANCE: lattice nozzle assembly (18), appropriate for set in reaction chamber of the fluidized-bed reactor, comprises the horizontally passing lower plate (14), the gas compression chamber under the lower plate and the stand gas pipes (20) that have the inner diameter, the upper end (26), and that pass upwards from the gas compression chamber through the lower plate. The lattice nozzle assembly comprises the nozzle head (22) with the gas duct for fluidizing gas supply from one of the stand gas pipes (20) into the reaction chamber and the canular ferrule (24), which is capable of durable fixation by dint of the welding round the stand gas pipe upper end. The nozzle head and the canular ferrule form the twist lock (30), which provides the quick joint and quick release of the nozzle head (22) and canular ferrule (24). Moreover, the canular ferrule (24) is composed of the upper surface, and the nozzle head (22) is composed of the horizontally passing upper portion and passing down core with the inner diameter, which is equal to the stand gas pipe inner diameter. Along with this, the core is capable of insertion in canular ferrule (24) in such a way that the core length is designed with a possibility of packing with the stand gas pipe, when the bottom face of the horizontally passing upper portion is packed with the upper surface of the canular ferrule for the turbulence prevention while supplying the fluidizing gas from the stand gas pipe into the gas duct.

EFFECT: nozzle head and canular ferrule quick joint and release.
