Description
Summary:This paper is intended to provide a general introduction to the subject and provide a background for the detailed scientific papers appearing later in the meeting. The various types of m.h.d. generator are briefly discussed and the basic theory of m.h.d. generation is described. The open cycle fossil fuel type of m.h.d. generator system in which the exhaust gases from the m.h.d. duct are used to power a steam turbo alternator generator is discussed in more detail and the major problem areas identified. These include the stability of the flow in the m.h.d. duct, the provision of long lived electrodes, air preheaters, seed recovery apparatus and the development of a suitable superconducting magnet. The influence of the parameters of the various components on the performance of the complete m.h.d./steam turbine plant is discussed.
