ABSTRACT:
A method and apparatus of operating a combination power plant which includes at least one large diesel engine provided with a turbocharger connected to receive exhaust gas from the engine, an exhaust gas boiler connected to receive exhaust gas from the turbocharger for utilizing heat energy in the exhaust gas to produce pressurized steam, and a steam turbine for converting energy in the steam produced by the exhaust gas boiler to electrical energy. When the engine is running at a high power output rate, a side flow of exhaust gas is removed from the flow of exhaust gas upstream of the turbocharger, the side flow being below 20% of the total exhaust gas flow from the engine. Heat energy in the side flow gas is used to refine the steam produced by the exhaust gas boiler before feeding it into the steam turbine.
