    专利说明:

    The invention relates to energy and can be used for fuel combustion, as well as in the chemical metallurgical industry.
    The purpose of the invention is to increase work efficiency by improving the uniform distribution of the secondary gas. . FIG. 1 schematically shows the proposed fluidized bed reactor, longitudinal section; in FIG. 2, section A-A in FIG. one.
    The fluidized bed reactor contains a chamber 1, divided from seki 2 by at least one partition 3 placed above the gas distribution grid 4 connected in each compartment 2 through its duct 5 and regulator to an independent source (not shown) of the primary gas supply. In the partition 3 there are holes 6 for supplying the secondary gas. VssGtgG pereborodki 3 may connect 0.6-4.0 m, preferably t 1.5-2.5 m.
    The reactor works as follows.
    In addition, secondary air can enter chamber 1 through openings 7 made in its walls, and to openings 6 through a channel 9 made in partition 3. Openings 6 can be placed in rows or lines at various elevations for example, 0.6 and 2 m. Holes 6 can be connected to different channels 9 for supplying the secondary pelvis, which, in turn, can be connected to different sources of gas supply for the necessary distribution of the latter over the height of chamber 1. Besides
    In addition, the openings 6 and 7 and the duct 5 of each compartment 2 can be connected to their own independent source of gas, which makes it possible to regulate the supply of the latter to the individual compartments 2.
    The reactor may contain separators 10. Pi 12 holes may be made in the chamber walls to return the captured particles, in separators 10. When a fluidized bed reactor is operated for burning fuel, the latter is fed into chamber 1 above partitions 3, and solid particles separate from gases in the separators 10, return to the reactor through the holes 11 and 12 in its walls. Through the holes 6 and 7 and the grate 4 serves air.

    Claims (1)
    [1]
    1. A fluidized bed reactor containing a chamber divided into compartments by at least one partition placed above the gas distribution grid connected in each compartment through its regulator to an independent source of primary gas supply, and secondary gas holes that are at least in one compartment, which is due to the fact that, in order to increase work efficiency by improving the uniform distribution of the secondary gas, the holes for the latter are made in the partition.
    2, The reactor according to claim I, about t and h and y and with the fact that the height of at least one partition is 0.6 to 4.0 m, mostly ls5-2.5 m.
