FIELD: process engineering.
SUBSTANCE: invention relates to decontamination of solid household wastes. Proposed method consists in feeding the afterburnt offgas heated to 1150°C-1250°C in turns to parallel flow channel two-way gas-air heat exchangers. Said heat exchangers, compressed air system, air turbine and generator make the electric power generation system. Note here that offgas flow feed is changed over to every next heat exchanger after heating of previous heat exchanger to 800-1000°C. Note here that offgas flow cooled in every said heat exchanger is fed after gas cleaning system into atmosphere. Note here that after heating compressed air is fed to every heat exchanger for it to be heated to 600-800°C and, further, to inlet of air turbine connected with electric power generator. Said compressed air gets cooled and fed to incinerator kiln.
EFFECT: lower costs and pollution, higher efficiency of power production.
