Development of Autonomous Heat Gun for Repair and Maintenance of Utilities

Abstract

In this article the authors present the of theoretical and experimental studies of gas-burning devices with chordal feed of gas jets. The optimum diameter of the nozzles, providing the necessary range of gas jets for high-quality mixing of fuel gas and air in the mixing chamber of minimum length is determined by calculation. According to the analysis of the parameters of the flame indirectly proved the reliability of the calculated data. Chordal flow of the gas jets and optimization of their range will significantly reduce the overall structural dimensions of the gas burner units. Short-flame gas-burning devices formed the basis for the creation of Autonomous heat gun, intended for repair and maintenance of engineering networks. To achieve a good heat gun is ensured by the motor fan, capable of generating high-pressure jet without connection to an external electrical network. Using of autonomous heat gun in the housing and communal services is very promising in comparison with analogues.
