By using CFD-simulation, plug length simulation of local resistance type plugged tee, which changes the flow direction, using equations of hydrodynamics was carried out. During simulation, velocity of medium in the thread of the collector system in which local input resistance was plugged tee, which changes the flow direction, was measured. Herewith for determination of this velocity and reduction of its distortion collector system simulation at different plug lengths was carried out.

The mixing and burning of natural gas with heated air in the reactor of carbon black obtaining have been analyzed. Commercial test results for the device of partially premixed components with single-flow burner have been considered. Construction peculiarities and operational conditions of single- and multi-flow burners have been examined.

Chemical processes of phosphorites reduction by natural gas have been examined in the presence of sodium sulphate. The exchange of soda fluxing additives for sodium sulfate decreases the reduction process temperature, when such valuable products as phosphorus sulfides are formed, namely P4S10. We have shown that such exchange allows to reduce the process power consumption.
