FIELD: engines and pumps.
SUBSTANCE: proposed method comprises feeding cleaning material, collecting cleaning products and their recovery or disposal. In compliance with this invention, said inner surface is subjected to effects of two-phase jet consisting of gaseous and dry cleaning materials. For this, acceleration Venturi nozzle is fitted into combustion chamber to displace there inside about its axes in horizontal and vertical directions. Compressed air is used as gaseous material. Cleaning materials dry particles or granules are ejected by compressed air into flow and, via acceleration device, toward combustion surface cleaned surface. Note here that after removal of dirt from said surface, dry cleaning material is evaporated. Said dry cleaning material represents dry ice bits or granules. Removed particles of carbon, soot and oxides are sucked off by dustless cup or vacuum cleaner.
EFFECT: better cleaning.
