Abstract

The invention relates to rotating fluidized bed burners and can be used in apparatus for burning powdered substances. The device can be used to improve the quality of mixing, burning and operation. The device works as follows. Spin the housing 1 and supply the gaseous component to chamber 3 through the manifold 14 and pipe 15. Powder material enters through pipes 8 and 9 into chamber 3. At the junction between pipes 8 and 9, part of the gas enters inside pipe 7, which improves the flow of powder material. The divider 12 contributes to the uniform distribution of the powdered material along the wall 10 and the shell 2. Some of the gases through the holes in the pylons 11 enter the cavity of the dissector 12, cools it and out through the wall 13 into the chamber 3. Pyrotechnic or other fuses are used for ignition. The reaction products move through the flue 4, the liquid sludge is exhausted through the nozzles 6. 1 C, ff, 1 sludge.

Description

The invention relates to the field of rotary burners and can be used in apparatus for burning powdered substances.

The aim of the invention is to improve the quality of mixing.

The drawing schematically shows the proposed device.

The device comprises a housing 1 with a gas permeable casing 2 disposed therein, which forms a reaction chamber 3 extending to the outlet duct k. On the end cap S at the junction with the shell 2, there are nozzles arranged evenly around the circumference. The nozzle 7 for feeding powdered material consists of fixed and rotating pipes, respectively, 8 and 9. On the front end wall 10 of chamber 3, a disk-shaped divider 12 with perforated wall 13 is installed through pylons II. The gaseous component feed system consists of a collector 14 and a nozzle 15f fixed in housing 1 .

The device works as follows.

Spin up the housing 1 and deliver the gaseous component to the

chamber 3 through collector 14 and nozzle 15. Powdered material is fed through pipes 8 and 9 into chamber 3. At the junction between pipes 8 and 9, the suit of gas enters inside nozzle 7, which helps to improve the flow regime of powdered material Divider 12 promotes uniform distribution of powdered material on the wall 10 and the shell 2, Part of the gas through the holes in the pylons 11, flows into the cavity of the dissector 12, cools it and leaves through the wall 13 into the chamber 3. To ignite, use pyrotechnic or other odor Liquid sludge AET che eez nozzle 6, the reaction products are moved through the gas duct,
