There were developed devices with porous coatings that can eliminate the appearance of cracks in the chambers and nozzles due to the powerful thermodynamic screen of three heat sources, and to arrange cutting of reinforced concrete structures with detonation high-temperature flares flowing from combustion chambers and nozzles cooled by capillary-porous coatings. In studies, the holography method was used. The expected economic effect from the one burner is approximately 200-300 $. The environment needs to be reduced by the cooling system’s energy consumption. The studied chambers and burners can be implemented in the thermal power plants, especially in the gas turbine equipment. Capillary-porous and flow-through cooling systems demonstrated high reliability, however, the first system can reduce the cooler consumption by tens of times (up to 80 times). The design and manufacturing of hybrid porous surfaces make them integrated and multifunctional, provides the possibility to work with higher critical loads, and enables a mobile process for monitoring the limiting condition of coatings.
