FIELD: chemical industry; methods and the devices for the heat recovery in the reactors with the fluidized layers.
SUBSTANCE: the invention is pertaining to the method and the device for the heat recovery in the reactor with the fluidized layer. The reactor with the fluidized layer contains the furnace, the heat-exchange chamber, the discharge channel connected to the lower part of the heat-exchange chamber used for removal of the material in the form of the particles from the heat-exchange chamber into the furnace, and essentially the vertical auxiliary channel for relocation of the material in the form of the particles from the heat-exchange chamber into the furnace and from the furnace into the heat-exchange chamber. The lower part of the auxiliary channel is supplied with the nozzles for the gas used for the pseudo-liquefaction process and with the tube for the stream for coupling of the auxiliary channel with the furnace. The upper part is supplied with the tube for the stream for coupling of the auxiliary channel with the heat-exchange chamber. The furnace, the heat-exchange chamber, the discharge channel and the auxiliary channel form the uniform construction having the discharge channel and the auxiliary channel located adjoining between the furnace and the heat-exchange chamber. The invention ensures the accurate regulation of the efficiency of the heat-exchange process for all sorts of the reactor loads.
EFFECT: the invention ensures the accurate regulation of the efficiency of the heat-exchange process for all sorts of the reactor loads.
