    The invention relates to devices for introducing additional transport agents into the pneumatic conveying pipelines, especially for the aerosol transport of any pulverized materials, for example, to the supply ducts for pulverized fuel suspended in the carrier gas to the pulverized coal burner or coal dust gasification reactor, and the pneumatic conveying pipe may be under higher pressure. The introduction of coal slurry with a gas carrier into a pressurized gasification installation is the main point of the entire coal gasification process, with a crucial importance for the uniformity of dust supply and the achievement of high ration ratios in the carrier gas. The known devices for feeding powdered substances to the reaction apparatus are characterized by jerky or uneven fluctuations in the feed rate. With continuous transport of dust in the aerosol range, there are no relatively low flow velocities (–5 m / s). To this are added the varying flow properties of a different plastic, which can lead to irregular transport in the pipeline. Already with a slight change in the structure of the drums compared to the normal state, it may happen that in pipelines that are well matched to the normal state of dust, the irregularity of transportation is observed. Particularly dangerous are knees, long horizontal pipelines and places of changes in pipeline sections. The aim of the invention is to improve the transportation conditions, ensuring high uniformity of pneumatic transportation. Uniform and stable transportation conditions are necessary in order, for example, when loading gasification installations to eliminate hazardous production situations that may be caused by interruption of the fuel supply. The objective of the invention is to ensure an even and continuous flow of dust-like materials in the pneumatic conveying pipelines and to eliminate the violation of the transport process. This goal is solved 43 by inserting a device for the controlled delivery of small amounts of additional transporting agent at critical points in the pipeline. A device that can be fitted to pipelines of any diameter provides for the distribution of additional supplied gas around the entire perimeter of the pipeline and reliably prevents the penetration of pipe into the supply pipeline for the additional transporting agent. It works without mechanical controls. With the aid of a device for introducing an additional transporting agent into the pneumatic transport pipeline, stabilization of the transport flow 4 is achieved even with pneumatic conveying of the fluid with poor flow properties. The goal is achieved by the fact that in the device DP, an additional transport agent is introduced into the pneumatic. transport piping containing installed coaxially supplying and discharging piping, mounted at the place of their connection sealed annular chamber connected to the source of the transporting agent, and a two-stage cylindrical bushing of elastic elastic material fixed by a larger step on the supply piping and placed by a smaller step having a conical chamfer, in the discharge pipe, on the inner surface of the discharge pipe in the area of the lower step of the sleeve is made a helical groove having a trapezoidal cross-sectional shape. The elastic stool hermetically closes the pipeline from the annular chamber until the excess pressure resulting from filling with gas in the annular chamber is sufficient for elastic deformation of the front part of the sleeve, and thus for opening, corresponding to the supplied amount of gas, a circular slit on the hub face. . When the circular gap opens, an additional transport agent distributed around the entire perimeter of the pipe and directed by the chamfer of the hub chamfer, enters the pipeline, which can also be under pressure. Inner diameter
