Abstract

1,158,862. Magnetohydrodynamic power plant. COMPAGNIE ELECTRO MECANIQUE. 25 July, 1966, No. 33277/66. Heading H2A. An MHD energy conversion apparatus includes a plurality of loops containing a conductive liquid disposed in a magnetic field and employs a gas in liquid emulsion as the working fluid in each loop which operates at constant temperature. Each loop is provided with a gas inlet region, an energy conversion region and a gas outlet region and the loops are assembled together such that the gas can pass from one loop to the adjacent loop and the sense of the energy conversion is the same throughout. As shown, gas is injected into the liquid in a first loop at 1 to form an emulsion 2 which passes through generating region 3 to transfer region 7 where the gas is separated from the liquid in the first loop and injected to form an emulsion with the liquid in the second loop. The gas passes from loop to loop through transfer regions 7 until it is separated from the liquid in the final loop by separator 4 and recirculated through heat exchanger 8, cooler 9, compressor 10 and high temperature heat exchanger 11 to injector 1. The temperature of the liquid in the loops is controlled by passing a liquid flow in the opposite direction to the gas flow through the apparatus. In the particular embodiment shown, the first two loops are maintained at the same temperature by injecting hot liquid at 15 in the second loop and removing it at bleed 12. The bled off liquid is heated in heat source 13 and then divides, a part going through valve 14 to injector 15. The remainder passes through valve 16 and heat exchanger 11 to be injected through battery 18 in final separator 4. The apparatus may have a plurality of inlet, conversion and outlet regions in each loop so that a plurality of parallel gas paths are provided.
