MHD (Magneto Hydro Dynamics) System is a new system of electric power generation which is said to be of high efficiency and low pollution. As its name implies, magneto-hydro-dynamics (MHD) is concerned with the flow of conducting fluid in presence of magnetic and electric field. This fluid may be gas at elevated temperature or liquid metal like sodium or potassium. The working fluid here is called plasma.
A MHD generator is a device for converting heat energy of fuel directly into electric energy without a conventional electric generator. The basic difference between a conventional generator and a MHD generator is in the nature of conductor. MHD converter system is a heat engine whose efficiency , like all heat engines , is increased by supplying the heat at the highest practical temperature and rejecting it at the lowest practical temperature. MHD power generation looks the most promising of the direct conversion techniques for the large scale production of electric power.
In advanced countries MHD generators are widely used but in developing countries like India it is still under construction. This construction work is in progress at Tiruchirapalli in Tamilnadu under joint efforts of BARC (Bhabha Atomic Research Centre), BHEL, Associated Cement Corporation and Russian technologists.
