Abstract (en)
[origin: EP0317110A2] A process to produce electricity and heat which involves combusting (10) fuel to produce a gaseous stream of combustion products, passing the gaseous stream through a turbine (14) to generate electricity, and to produce a gaseous exhaust stream, adding additional fuel to the exhaust stream, to provide a fuel-rich combustible gas stream having fuel in excess of the oxygen in the combustible gas stream, catalytically treating (18) over a reducing catalyst of combusting the fuel-rich combustible gas stream in a reducing atmosphere to produce a heated oxygen-depleted gaseous stream, converting (22) at least a portion of the heat in the oxygen depleted stream into a steam, adding air (24) to the oxygen-depleted stream to produce a stoichimetric excess of oxygen in the resultant stream relative to fuel present in the resultant stream, passing the resultant stream over an oxidizing catalyst (26) to produce an oxidized gaseous stream, removing heat (28) from the oxidized stream, and venting (32) the resultant cooled stream. Preferably, at least some of the oxidized stream (36) is cycled to the step of combusting fuel. An apparatus system for carrying out this process is also provided.
