Document Type and Number:
WIPO Patent Application WO/2015/059653
Kind Code:
A3
Abstract:
A method for recovering energy from waste, in particular urban and/or industrial waste, comprising a step of incinerating the waste in a furnace (1), then conveying the combustion gases from the furnace into a recovery boiler (5) in order to produce water vapour, the combustion gases next being sent to a treatment unit (10) before being discharged into the atmosphere; an auxiliary gas is burned outside the furnace, in an outer superheater (12); the water vapour exiting the boiler (5) passes through the superheater (12) where it is superheated before being injected into a turbine (T), the combustion fumes from the auxiliary gas (19) exiting the superheater are at a temperature lower than the maximum value allowable in the furnace, and these combustion fumes from the auxiliary gas are injected into the facility at the recovery boiler, and are discharged with the combustion gases from the furnace in order to be treated in the treatment unit (10) provided for the furnace.
