摘要

Waste is treated in a furnace (6) which is pressurized by injecting thereinto either air which is strongly enriched with oxygen (even up to 100%), so that the temperature of oxidation of said waste, after a starting step wherein external fuel and said combustion supported are used, reaches so high values as to cause a substantial sublimation of said waste and its complete molecular cracking. The vapors resulting from the hyperbaric sublimation process are then submitted to a rapid adiabatic expansion or semi-adiabatic expansion in a suitable volume (23) to cause a first strong cooling of said gases, down to values which may be then abated by usual heat-dissipating systems (25-26).
