Cogeneration of electricity and carbon dioxide with low NOx combustion of vaporizable liquid fuels, particularly alcohols and hydrocarbons, is achieved by feeding the vaporized fuel admixed with a limited amount of air to a porous fiber burner and effecting flameless combustion on the outer surface of the burner to yield a flue gas with a very low content of NOx and other pollutants. The liquid fuel is vaporized by injection into hot combustion air preheated by heat exchange with the flue gas while heat from the burner is utilized to produce high-pressure steam which is supplied to a steam turbine that drives an electric generator. The flue gas is then passed through an absorption system for the recovery carbon dioxide, part of the steam being used in the absorption system. When desired, recovered carbon dioxide can be liquefied with refrigeration produced by the cogeneration system.
