description: The given work is devoted to the studying of the combustion of liquid ammonium bifluoride droplets in oxygen in the presence of methane in a "tunnel burner" reactor to obtain hydrogen fluoride and the development of recommendations on the design and technological modes for an industrial reactor. The research set the following goals 1. Carrying out calculations of the heat balance of the reacting system, taking into account the process of evaporation of ammonium bifluoride and radiation heat losses. 2. Carrying out calculations of ammonium bifluoride drops size when it is sprayed with a nozzle for a given productivity, typical for a pilot reactor. Development of a nozzle design for a pilot reactor. 3. Development of a mathematical model of a "tunnel burner" reactor for the combustion of atomized ammonium bifluoride in oxygen in the presence of methane. 4. Implementation of the developed model in the commercial package Ansys Fluent. 5. Carrying out the tuning of the developed model based on the available literature data on the evaporation of droplets of various substances. 6. Research using the created model of the effect of various process parameters on the evaporation length of a drop of ammonium bifluoride and other characteristics of the process. 7. Development of recommendations on the design and technological parameters for an industrial of the "tunnel burner" reactor for the combustion of ammonium bifluoride. The give work was carried out on the basis of Graduate School of Applied Mathematics and Computational Physics. Calculations of the nozzle design of the "tunnel burner" reactor for spraying liquid ammonium bifluoride have been carried out. A numerical simulation of the evaporation and combustion of a droplet of liquid ammonium bifluoride using the Ansys Fluent software package has been carried out; the main physical and technological factors affecting the droplet evaporation process have been determined, recommendations on the design and technological parameters of the reactor were developed.
