FIELD: construction engineering; units for thermodynamic treatment of surfaces - abrasive jet treatment, application of decorative and anticorrosive metallized or polymer coats. SUBSTANCE: unit has housing, liquid fuel and gaseous oxidant supply branch pipes, combustion chamber, swirler, axial tube for delivery of working medium and accelerating nozzle with circular fuel vaporizer mounted on its outer surface; fuel fed to this vaporizer evaporates and enters combustion chamber where homogeneous combustion process is effected. Combustion process is enhanced due to change of this process from heterogeneous to homogeneous in combustion chamber. EFFECT: enhanced efficiency. 2 dwg
