Abstract. Objective of the work was to study effect of the rate of air-mixture flowing through the first and second stages of reactor on the process of coal-dust plasma-chemical preparation after the flame tube. As concentration of coal dust in the air mixture flowing to the boiler can vary considerably during its operation, the studies were carried out for several rates of the concentrations. Temperature was calculated for characteristic zones of the reactor. The results are presented in the form of table and graphs. Analysis of the results shows that the reactor under the study, when operating with the boiler TPP-210, can ensure the coal-dust plasma-chemical preparation at all rates of the coal dust concentration in the air mixture. Temperature of the pulverized coal flare at the outlet from the flame tube is within the range of (1000-1400) 0С due to the device, which regulates the air mixture flow passed through the reactor during its operation.

Keywords: plasmatron, reactor, coal dust, air mixture, coal dust in the air mixture.
