This paper discusses a cogeneration system for the production of electricity and carbon dioxide with low NO{sub x} combustion of liquid fuel. It comprises a high- pressure steam boiler, a porous fiber burner within the boiler, a countercurrent heat exchanger connected to receive the flow of flue gas from the boiler, an air blower connected to the heat exchanger for the flow of air countercurrent to the flow of the flue gas, a feed tube connected to the porous fiber burner, a pipe connected for the flow of hot air from the heat exchanger to the feed tube, a pump connected to feed liquid fuel to the feed tube, a steam turbine connected to receive and expand high-pressure steam from the boiler and to return expanded and condensed steam to the boiler, an electric generator driven by the steam turbine, a flue gas blower connected to receive flue gas from the heat exchanger, and an amine absorption system for the recovery of carbon dioxide from flue gas supplied by the flue gas blower, the absorption system having a stripping column with a reboiler connected so as to be heated by steam withdrawn through a port at an intermediate pressure stage of the steam turbine.
