INTRODUCTIOINTRODUCTION:N:

• MHD Power generation is a new MHD Power generation is a new system of electric power generation system of electric power generation

• high efficiency and low pollutionhigh efficiency and low pollution

• converting heat energy of a fuel directly converting heat energy of a fuel directly in to electrical energyin to electrical energy

• closed cycle MHD Power generation is closed cycle MHD Power generation is one of attractive and advanced one of attractive and advanced technologies technologies

PRINCIPLE OF PRINCIPLE OF MHD :MHD :

• Faradays Law of electromagnetic Faradays Law of electromagnetic inductioninduction

• The solid conductors are replaced The solid conductors are replaced by gaseous conductorsby gaseous conductors

• Gas is passed at a high velocity Gas is passed at a high velocity trough a powerful magnetic field, trough a powerful magnetic field, current is generated and can current is generated and can extracted by placing electrodesextracted by placing electrodes

Energy Conversion Alternatives StudyEnergy Conversion Alternatives Study (ECAS)…(ECAS)…

The MHD system was The MHD system was found to have the highest overall found to have the highest overall efficiency of the systems studiedefficiency of the systems studied

Cost of electricity Cost of electricity produced by MHD& fuel prices was produced by MHD& fuel prices was one of the lowest of the systems one of the lowest of the systems

ADVANTAGESADVANTAGES::

• Large amount of power is generated . Large amount of power is generated . • It has no moving parts, so more It has no moving parts, so more

reliable.reliable.• The closed cycle system produces The closed cycle system produces

power free of pollution .power free of pollution .• It has ability to reach the full power It has ability to reach the full power

level as soon as started.level as soon as started.• The size of the plant is considerably The size of the plant is considerably

smaller than conventional fossil fuel smaller than conventional fossil fuel plants .plants .

  CONCLUSION:CONCLUSION:

• Cheap generation of electricity and Cheap generation of electricity and conservation of known resources of conservation of known resources of fossil fuelfossil fuel

• undertakes development efforts in undertakes development efforts in advanced fields of technologyadvanced fields of technology

• A better understanding of super A better understanding of super conducting technologyconducting technology
