Power generation using fossil fuel-fired steam supply systems involves the conversion of the chemical energy in the fuels into electrical energy. This energy conversion requires many complicated systems and components. The steam generator gets relatively cheaper and smaller in size as the fuel consideration changes from solid coal to oil and to gas. This is why the type of fuel, fuel transportation, fuel handling and storage at site, fuel processing requirements before combustion, and the final products of combustion are very important at the inception of a power generation project, especially with regard to siting and environmental effects. The fuel systems, whether pulverized coal, oil, or gas, must be carefully designed and engineered to match the rate of steam generation and energy production.
Edison GTD Energy Services (Edison GTD) will construct and operate power plants based on proven, rugged, baseload power generation technology burning fossil fuels -coal, oil, and gas for energy production in Nigeria. Power Stations with nameplate capability of 300MW and below will be based on Circulating Fluidized Bed (CFB), subcritical steam supply boiler with tandem compound, single reheat, two flow turbine generator. All power stations with nameplate capability of 400MW and above will be based on supercritical steam supply system with tandem compound or cross compound turbine generator depending on the capability.
