METHOD AND SYSTEM FOR USING SOLAR ENERGY AND A FOSSIL FUEL TO GENERATE ELECTRICITY

摘要

The invention relates to a method for using a fuel, preferably fossil fuel, in particular lignite, to generate electricity. In order that the generation of electricity by means of fuels, such as fossil fuels, for example in the form of bituminous coal or lignite, or in the form of biomass, can be made more economical and environmentally friendlier, according to the invention, solar radiation (4) is concentrated by means of at least one mirror (3), the thermal energy of the concentrated solar radiation (4) is used to produce and/or superheat steam and/or to heat air, and the steam produced and/or superheated by means of the concentrated solar radiation (4) and/or the heated air is coupled in-line as a thermal heat source into a power plant process operated with a fuel.
