ABSTRACT:
There is provided a method and an apparatus for producing electrical power nd for the simultaneous heating of fluid by means of a magnetohydrodynamic (MHD) generator. The method comprises providing a heating means for heating a mixture of liquid metal and an organic liquid to form a two-phase liquid metal-vapor flow, directing the two-phase liquid metal-vapor through a MHD-generator to generate electricity, condensing the vapor phase from the two-phase liquid metal-vapor to form liquid metal carrying organic liquid droplets, and recycling the metal and organic liquid droplets to be reheated by the heating means. The MHD apparatus comprises a closed duct system containing a mixture of liquid metal and an organic liquid, a heating means for heating the mixture in the closed system, a MHD-generator, located along the flow path of a two-phase liquid metal-vapor flow formed by the heated mixture, means for condensing the two-phase flow to form a single phase flow of metal liquid containing organic liquid droplets, and means for propelling the single-phase flow to be reheated by the heating means.
