REPOWERING OF SLOUGH ESTATES FOR OPTIMUM ENERGY CONVERSION.

This paper will provide the basis for replacement of an ageing plant, and will enable the existing steam turbines to work as part of a high efficiency cycle. The principles relating to the combined generation of steam and electrical energy are reviewed for existing and possible plant configurations, with a view to optimizing the energy conversion. the choice of a gas turbine and fully fired heat recovery boiler to provide extra power plus steam for existing purposes is shown to be justified by the savings in fuel and other operating costs over a typical year's operation.
