MHD GENERATORS

       Magnetohydrodynamic (MHD) power generation is an advanced technology for generating electrical power from fossil fuels by passing an electrical conducting fluid through a magnetic field without rotating machinery or moving mechanical parts.

       In principle, any electrical conducting fluid can be used as the working fluid, and power generation has been demonstrated with a number of such fluids, varying from liquid metals to hot ionized gases.

       The absence of moving machinery allows the MHD generator to operate at much higher temperatures than other power generation systems and, therefore, higher efficiencies can be reached.

       A key component of the MHD generator is the superconducting magnet, which produces the magnetic field necessary for the energy conversion process.

       A MHD/steam plan can achieve efficiencies of up to 60% with less environmental impact than from any other direct coal-burning technology. Retreofitting and/or repowering of existing thermal power plants is possible with a significant increase of the efficiency of the plant.

       Efficiencies greater than 65 70 % can be reached if a triple cycle, including an MHD generator, a gas turbine and a steam turbine, is utilized.
