This invention relates to a method and apparatus for vitrification and power generation, A vitrification and power generation apparatus comprises a glass-forming furnace (1) including inlets (3, 5) for feedstock and inlet gas including fuel gases or oil and pre-heated air, and a gas outlet (9) from which furnace flue gases are fed; heat recovery means (25) through which furnace flue gases are fed to reduce their temperature the heat recovery means (25) also pre-heating the air fed to the furnace; and a boiler (11) coupled to the heat recovery means (25) including a gas inlet through which the furnace flue gases are fed to the boiler (11), a steam outlet (13) and a gas outlet (15) through which boiler flue gases are fed, the boiler flue gases for feeding to a gas treatment system (17) in which the boiler flue outlet (5) is coupled to two outlet paths (19, 21) and means for splitting the flow such that one outlet path (19) is for feeding boiler flue gases to a gas treatment system (17) and the other outlet (21) path leads to the furnace inlet (5), to the furnace outlet (9) or to the boiler inlet (10), whereby part of the flow of boiler flue gas is recirculated.
