Abstract

Apparatus for, wholly or partly, converting an existing polluting fuel electrical generating station, from a polluting fuel to natural gas, while retaining the existing steam turbine electrical generator of the existing station and having, a gas turbine, a gas turbine powered electrical generator which supplies power to a grid, a heat recovery steam generator connected to the exhaust of the gas turbine to generate steam, and, a steam connection between the heat recovery steam generator, and the existing steam turbine electrical generator in the existing plant, so that the converted plant generates a first electrical supply from the gas turbine powered generator, and generates a second electrical supply from the existing steam turbine powered generator. Also disclosed is a method of converting an existing polluting fuel electrical generating station, to natural gas, while retaining the existing steam turbine electrical generator of the existing station in which a gas turbine prime drives an electrical generator, for generating a first electrical supply, the exhaust from the gas turbine being connected to an heat recovery steam boiler, and in which the heat recovery steam boiler is connected to drive the steam turbine of the existing generating plant to generate a second electrical supply.
The polluting fuel steam boiler of the existing plant may be wholly or partly disconnected from the existing steam turbine.
