Magnetohydrodynamic power generator, any of a class of devices that generate electric power by means of the interaction of a moving fluid (usually an ionized gas or plasma) and a magnetic ohydrodynamic (MHD) power plants offer the potential for large-scale electrical power generation with reduced impact on the , several countries have undertaken . Dipak K. Sarkar, in Thermal Power Plant, Magnetohydrodynamic (MHD) Generator. The MHD generator or dynamo transforms thermal energy or kinetic energy directly into electricity. MHD generators are different from traditional electric generators in that they can operate at high temperatures without moving parts. Magnetohydrodynamic power generation provides a way of generating electricity directly from a fast moving stream of ionised gases without the need for any moving mechanical parts - no turbines and no rotary generators. MHD power generation has also been studied as a method for extracting electrical power from nuclear reactors and also from. Capital cost generally increases with weight according to some power law, C ∼ W p, where C is cost, W is weight, and p has a value probably somewhat less than unity. Engine -driven generators usually, but not always, generate alternating current at a power-line frequency, 50 or 60 Hertz, and less commonly, at high frequencies, or Hertz.
II. MAGNETOHYDRODYNAMIC POWER GENERATION The magnetohydrodynamic power generator is a device that generates electric power by means of the interaction of a moving fluid (usually a ionized gas or plasma) and a magnetic field. As all direct conversion processes the MHD generators can also. The basic electrical characteristics of MHD generators are power output, which is generated in working fluid volume, and local electrical efficiency η, defined as a ratio of electrical power output density to electromagnetic body force power density (×) (×).In MHD generators, the values of and (×) are negative. Thermodynamic characteristics include enthalpy extraction. The present U.S./U.S.S.R. joint report on open-cycle MHD electrical power generation first examines general problems of MHD power plants, including discussion of general plant characteristics, selection of optimal configurations and plant layouts, evaluation of technical and economic aspects of open-cycle MHD power plants along with an outlook for their future application in power generation. Magnetohydrodynamic (MHD) power generation process is basically based on the physics background of space plasma. The basic principle is the Faradays Law of electromagnetic induction.
In electricity generation, a generator is a device that converts motive power (mechanical energy) into electrical power for use in an external s of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand first electromagnetic generator, the Faraday disk, was invented in by British scientist. References concerning the mathematical theory of the MHD power generators may be found in L. Dragoş’ s book [ 1], Chapter 4. In the last years, new applications of MHD generators t o.

The paper first provides a brief description of experience and problems encountered in the design and operation of conventional fossil-fueled steam generators used in electric power plants. Thereafter, the unique operating conditions and design requirements for MHD-steam generators are discussed. Then the operating experience gained from the U plant in the Soviet Union is reviewed.
