A gas turbine topping and an open-cycle MHD generator topping, CO2-free combined systems are proposed with taking into account the central- and dispersed dual structure of power generation systems. The conducting fluid may be either a conducting gas, a plasma, or a liquid metal. The simplest of the plasma MHD systemt concepts is the open-cycle MHD system. In it an alkali metal compound is added directly to very-high-temperature combustion products and used as the MHD generator fluid.
