The stages of development of thermal tools with intensifiers of combustion of fuel components are described. Studies for obtaining the manifestation of detonation in the free stream of thermal tools during combustion of fuel components have been performed. The design features of the development of gasoline-air thermal tools, which allow intensifying the combustion processes of fuel components, are presented. However, due to the simplicity of operation and organization of feeding fuel components with gasoline-air burners, their use as working bodies of mechanized equipment is urgent. Increasing the power of gasoline-air burners without considerable development of their overall dimensions and increasing the size of the burner flame is possible due to intensification of combustion processes. The use of gasoline-air burners as working bodies of mechanized thermal units is restrained by their relatively low power, the increase of which quickly increases their overall dimensions. Also, the thermal tools with supersonic flare for various technological operations, for rock destruction during slot excavations are considered. The experiments have shown that with the increase in the number of ejection windows, the size of the flare and the power of shock waves increase. To determine the heat transfer parameters of supersonic high-temperature gas jets, a special burner was developed with the possibility of using gasoline, diesel fuel and propane gas as fuel. Gasoline-air burners allow using detonation combustion in them to increase the productivity of thermal destruction of rocks, and to automate the start-up of the burners in operation. Experimental studies have shown that gasoline-air burners, with a combustion intensifier, allow using detonation combustion in them to increase the productivity of thermal destruction of rocks, to automate the start-up of thermal tools in operation
