ABSTRACT:
In the disclosed thermal power plant an alkali metal vapor energy conversion circuit is arranged in heat transfer relationship with an additional circuit whose working medium does not vigorously react with alkali metal. Diphenyl, terphenyl are disclosed as suitable media. The additional circuit may in turn be in heat transfer relationship with a steam circuit, in which event the additional circuit is interposed between the alkali metal energy conversion circuit and the water vapor (steam) circuit. The upper process temperature of the interposed energy conversion circuit is between about 420.degree. and 480.degree. C, preferably between 440.degree. and 470.degree. C. The transfer of the heat from the interposed circuit to the water vapor circuit preferably takes place in a temperature range in which the absorption by the water vapor circuit proceeds substantially isothermally.
