THE VARIABLE OPTIMIZATION OF MHD GENERATOR WITH ELECTRIC OUTPUT OF 10 KW

Abstract

The variables of magnetohydrodynamic (MHD) generator with an electric output of 10 kW is optimized for the application of bi-plant method-electricity generation. The MHD generator, which converts kinetic energy directly into electricity, can operate in high temperature areas of generation technology. It is considered to increase the total efficiency of the fossil power plant by adopting the bi-plant method that generates electricity by both turbine and MHD generator. Flue gas with a high temperature of approximately 3000 K from the power plant was used for the generation of electricity from its flow in the magnetic field, where electricity was produced directly without turbine facility from such an MHD generator. The magnetic flux density of a magnet, conductivity of the plasma state of flue gas, and velocity of gas are analyzed to help design the MHD generator in terms of power output in an electric output condition of 10 kW. The magnetic flux density, velocity, and geometrical variables were affected by the power in the MHD generator. Finally, the geometrical variables are derived for the experimental characterization of the MHD generator with an electrical output of 10 kW.
