Abstract The 651 MWe coal-fired River Rouge Power Plant (RRPP) of Detroit Edison, a subsidiary of DTE Energy, was constructed in the late 1950's at a location near integrated steel mills equipped with coke oven batteries and blast furnaces. The plant is also located adjacent to an oxygen pipeline. The power plant includes several boilers and turbine generators, with the tangentially fired Unit #2 at 260 MWe of capacity and the wall-fired Unit #3 at 280 MWe of capacity. In an effort to provide customers with least-cost power, and to minimize the environmental consequences of power generation, RRPP fires coke oven gas (COG) when available and will soon fire blast furnace gas (BFG) from the adjacent steel mill complex. The coke batteries are owned and operated by Energy Services, the non-regulated business units of DTE Energy. The units also fire a small amount of natural gas for flame stabilization. This paper describes the present and planned use of alternative fuels at RRPP, focusing on the COG. It also considers the BFG program, and several additional opportunity fuels. It also considers the potential for oxygen-enhanced combustion at RRPP, a process now under consideration. The paper focuses upon the characteristics of the alternative fuels, the current and potential methods of firing these fuels, the typical frequencies and percentages of fuel supplied by COG and BFG, issues of potential combustion control, and the consequences of their use. Consequences include improved pulverizer performance and coal combustion, reduced airborne emissions, reduced ash management issues, and related mechanical systems considerations.
