I

The invention relates to dust preparation equipment for power plants and can be used in combustion schemes for high-moisture fuels.

Known divider-dust condenser, containing a cylindrical body with a concentrated blend of the mixture and placed in the lower part of the swirler, and in the upper coaxially pipe for removal of weakly dusty agent f 1 J.

The disadvantage of this device is the complexity of arranging a dust separator with burners located on the same floor, which has a negative effect on the uneven distribution of dust.

Also known are separators-dust condensers containing a cylindrical body fitted with fittings for withdrawing the condensed mixture with a swirler placed in its lower part, and in the upper part with a coaxial pipe for diverting the slightly dusty agent G2}.

In these x-dust concentrator units, there is also an uneven distribution of the concentrated mixture between the burners.

The aim of the invention is to increase efficiency by increasing the uniformity of the distribution of dust in the nozzles.

The goal is achieved by the fact that the splitter-dust concentrator is equipped with a shell, covering the nozzle for removal of the slightly dusty agent with the formation of an annular

ts of the channel divided by longitudinal partitions into an equal number of nozzles of the number of compartments, each of which is connected to its own nozzle of the concentrated mixture.

In “FIG. 1 schematically shows a splitter-concentrator, longitudinal section; FIG. 2 is a section A-A in FIG. one.

The separator-dust concentrator contains a cylindrical body 2 fitted with fittings 1 for discharge of the concentrated mixture with a swirler 3 placed in its lower part, and in the upper part with a coaxial nipple k for removing the slightly polluted agent. The separator-dust concentrator is equipped with a shell 5 covering the nozzle A to drain a low-dust agent with the formation of an annular channel 6, divided by longitudinal partitions 7 into an equal number of unions 1 number of compartments, each of which is connected to its own fitting 1, a concentrated mixture.

Divider-dust concentrator works as follows.

The dust and gas flow enters the lower part of the body 2, the swirler 3 twists the blades. in the pipe 4 and in the annular channel 6, dust particles, mixed in the space between the housing 2 and the shell 5, flow down and are ejected by a slightly dusty gas stream passing through the annular channel 6, which provides even distribution of dust between the burners.

The installation of a heat concentrator divider in the boiler dust system makes it possible to increase the reliability of its operation due to the uniform thermal load of the burners, reducing the likelihood of slagging and burn-out of the screen surfaces of the furnace chamber. In addition, the arrangement of the splitter of the dust concentrator with the burners of the same Rus is improved.
