1,086,610. MHD power plant. SIEMENSSCHUCKERTWERKE A.G. June 13, 1966 [June 12, 1965], No. 26328/66. Heading H2A. In an MHD power plant, seeding material (e.g., potassium carbonate) in solid form is fed from a storage container 1 (which may be followed by a grinding mechanism) to a mixer 1b in a heat exchanger 3, where it is heated by the waste gases leaving the MHD generator duct 4. The heating fluidizes (e.g. evaporates) the seeding material and also chemically decomposes it by an endothermic reaction. The seeding material is mixed in solid, liquid or gaseous form with additional combustion air (which may be enriched with oxygen) supplied to the mixer by a compressor 1a. The mixture is supplied as a fluid through a duct 9 to a burner nozzle 11 which is also fed with fuel oil from a storage container 12. The heat recovered from the waste gases by the endothermic decomposition of the seeding material is thus supplied to the combustion chamber 14. If means for recovering the seeding material in liquid form from the waste gases is provided, the recovered material may be sprayed in liquid form into the additional combustion air in the heat exchanger. It is stated to be known to inject a mixture of soft soap and diesel oil into the combustion chamber, whereby an ionized gas is obtained after combustion.
