METHOD FOR COOLING OF TORCHES-LANCES WITH GASEOUS TECHNOLOGICAL MEDIUMS

摘要

A method for cooling of torches-lances with gaseous technological mediums comprising the supply of technological cooling gas in working volume with further heat removal, at that technological gas is supplied in “parallel flow” inside of working volume with it compressing, with pressure drop and increase (rise) of kinetic energy (rate), second compressing of technological gas with rate increasing its and temperature decreasing with further addition of multi-pass rotation moving in ring working channel for improvement or heat removal and introduction of heated technological gas in working space of unit (furnace).
