초록

A method of using internal combustion engine exhaust in a combined cycle power plant is disclosed, wherein the quality and distribution of exhaust to the boiler space of a steam generated electric power plant is controlled to achieve greater system efficiencies, and wherein exhaust pollutants are reduced. Outside air is blended only with that portion of the exhaust that passes through the burner ports as secondary or higher level combustion gas. The remainder of the exhaust is provided to the boiler space by a route other than through the burner. The hig...
