Magneto hydro dynamics power generation is a non-conventional energy resource used in modern systems. Due to high demand of coal, it is necessary to search for other alternative heat source to drive the magneto hydrodynamics power plants. The liquid metal like alumi-num, manganese, copper and silver can be employed due their improved thermal conductivity and flow characteristics. The magneto hydro dynamics power generation process needs high temperature heat source for converting the inert gas into ionized plasma. A regenerative heat exchanger is employed for heat transfer between melted metal from source chamber to argon gas chamber. The heat transfer coefficient between the liquid metal flow and inert gas is high according to flow conducting material. This work deals with the inert gas plasma which is produced from liquid aluminium and this can be used for recycling. This system proves only 36% of aluminum is required than that of regular MHD system using coal as a heating source.

Abstract


Magneto hydro dynamics power generation is a non-conventional energy resource used in modern systems. Due to high demand of coal, it is necessary to search for other alternative heat source to drive the magneto hydrodynamics power plants. The liquid metal like alumi-num, manganese, copper and silver can be employed due their improved thermal conductivity and flow characteristics. The magneto hydro dynamics power generation process needs high temperature heat source for converting the inert gas into ionized plasma. A regenerative heat exchanger is employed for heat transfer between melted metal from source chamber to argon gas chamber. The heat transfer coefficient between the liquid metal flow and inert gas is high according to flow conducting material. This work deals with the inert gas plasma which is produced from liquid aluminium and this can be used for recycling. This system proves only 36% of aluminum is required than that of regular MHD system using coal as a heating source.
