    The invention relates to energy and can be used in devices for burning toshgawa,
    The purpose of the invention is to simplify the design,.
    FIG. 1 shows a circulating fluidized bed reactor, vertical section; Fig, 2 section in Fig.1; on fig.z section bb on fig; Fig. A shows the exhaust pipe location option; on fig.Z - a section on fig „4e
    The circulating fluidized bed reactor contains a vertical combustion chamber 1, the upper current 2 of one side wall 3 of which is bent towards the upper section 4 of the opposite side wall 5 sec. To overlap the chamber 1, framing the horizontal vortex separator 6 and channel 7 for The passage of gas from chamber 1 to separator 6 is connected to the fly ash pipeline and the exhaust gas duct through at least one hole 9 in the frame. The exhaust gas duct is installed in the form of at least one exhaust pipe iOj introduced by the entrance section 1 1 through at least one hole 9 in the frame of the separator 6 into the cavity of the latter, and the pipeline 8 of the ash is connected to the combustion chamber 1. The cotton tube 10 can be part of its length in the gas passage 7 or in the initial zone of the latter, and can also be inclined to the horizon at an angle of IS 60. The longitudinal axis of the opening 9 (holes) in the frame of the separator 6 can be located radially to the longitudinal about and the last, and the inlet section 11 of the exhaust pipe 10 (pipes) can be directed longitudinally to the separator axis. All walls of the combustion chamber 1 are formed by pipes that are welded to each other and form the heat transfer surfaces of the boiler connected to the circulation circuit of the boiler. Device 12 for fuel supply located in the lower part of the combustion chamber 1. The devices 13 and 14 are also located here for supplying primary and secondary gases. Near the combustion chamber 1 there is a convective part 15, which is made of tubular walls, the wall 5 being the common length. chambers 1 of the combustion and convective part 5, and in the latter heat transfer surfaces 16 are located. Pipeline 8 (pipelines) of entrainment is made of two parallel walls 3 and 17. Channel 7 for gas passage is connected to separator 6 tangentially. The cross section of the exhaust pipe 10 (s) satisfies the requirements of aerodynamics.
    During reactor operation, the solid particles contained in the flue gases leave the combustion chamber and supply 5 dts to the separator 6 through channel 7 - dp of the gas passage. Separated solid particles return to the combustion chamber 1 not into the combustion chamber 8, and the lower part of the piping water 8 of the entrainment can be made into the hole in which the secondary gas (air) supply device 14 is placed to control the function of the entrainment pipeline 8 Purified furnaces
    5 gases through the exhaust pipe 10 (pipes) are supplied to the convective part 15, to prevent erosion of the wall of the separator 6, made of pipes, and the exhaust pipes 10 facets ana pokr
    Q tiyam, resistant to fire and erosion, such as mortar Exhaust pipes 1 O may have a square cross-section. The combustion chamber 1 may be made uncooled.
