Abstract
1,150,017. MHD power plant. CENTRAL ELECTRICITY GENERATING BOARD. 2 Oct., 1967 [7 Oct., 1966], No. 45005/66. Heading H2A. In an open-cycle MHD power plant wherein fossil fuel is burnt to provide combustion gases which are passed through a generating duct at sub-atmospheric pressure, the seed material is ionized before mixing with the combustion gases. The potassium or caesium seed material is fed in as a vapour, possibly with a small amount of carrier gas, at an inlet 25 and is ionized by an alternating or direct potential applied between electrodes 27 before being injected into the combustion gases through a nozzle 24. To minimize the decrease in ionization occurring as the seeded combustion gases pass through the generator duct 14 it is necessary to have a strong magnetic field and a low static gas pressure. For the latter reason, the combustion gases are passed through a convergent-divergent accelerating nozzle 13 to increase the velocity and reduce the pressure below atmospheric. The pressure is brought back to atmospheric by means of a convergent-divergent nozzle 20 and a compressor 22 before the gases are discharged at 23. The seed may be ionized by other means, e.g. an electron beam or thermal means such as an electric arc or a separate very high temperature combustion system.
