Abstract: The invention relates to an integrated power plant, which burns fuel using an oxygen-enriched stream in a combustion furnace and converts emissions of air pollutants and carbon dioxide into byproducts. The combustion flue gas stream, after leaving an economizer of a steam generation system, splits into stream A and stream B. Stream A recirculates back to the combustion furnace through the first flue gas recirculation fan for combustion temperature control. Stream B, after passing through a dust collector for fly ash removal, a series of condensers for byproduct recovery, and the second flue gas recirculation fan, mixes with an oxygen-enriched stream from an air separation unit and flows back to the combustion furnace. The plant does not need an exhaust stack and does not discharge combustion flue gases into the atmosphere.
