摘要： A fossil fuel is burned substoichiometrically in the combustor (10) of a MHD power plant to produce a high temperature, fuel-rich product gas (7). The product gas is passed through a MHD channel (12) to generate electricity. A reducing agent (9), preferably natural gas or hydrocarbon, is injected into the fuel-rich product gas (7) leaving the MHD generator (14); and the resulting mixture is held at a temperature in the range of 950.degree. C. to 1500.degree. C. for about 1 second to permit the reducing agent to decompose a portion of the nitrogen oxides formed in the combustor. The fuel-rich product gas (11) then passes thru an afterburner (18) wherein combustion is completed and any excess reducing agent is consumed.

摘要： According to the present invention, coal combustion gas is the primary working fluid and copper or a copper alloy is the electrodynamic fluid in the MHD generator, thereby eliminating the heat exchangers between the combustor and the liquid-metal MHD working fluids, allowing the use of a conventional coalfired steam bottoming plant, and making the plant simpler, more efficient and cheaper. In operation, the gas and liquid are combined in a mixer and the resulting two-phase mixture enters the MHD generator. The MHD generator acts as a turbine and electric generator in one unit wherein the gas expands, drives the liquid across the magnetic field and thus generates electrical power. The gas and liquid are separated, and the available energy in the gas is recovered before the gas is exhausted to the atmosphere. Where the combustion gas contains sulfur, oxygen is bubbled through a side loop to remove sulfur therefrom as a concentrated stream of sulfur dioxide. The combustor is operated substoichiometrically to control the oxide level in the copper.

摘要： A system for generating non-polluting fuel and a burner for using such fuel to produce energy in the form of heat with a non-polluting exhaust, together with means for utilizing such exhaust to produce supplementary direct current power is disclosed. An electrolyzer is operated to produce hydrogen and oxygen in gaseous form which is then stored in suitable fuel tanks. As needed, the fuel is combined with air and supplied under pressure to a combustion chamber where the mixture is burned, producing heat and a pollution free exhaust. The heat so produced may be used as a conventional heat source to generate steam, drive a turbine, or the like, while the combustion gases are directed to a magnetohydrodynamic generator to produce an electrical current which is usable in any desired manner.

摘要： An MHD generator includes external electrical connectors between adjacent discrete electrodes in one wall of the generator duct, which has opposed electrodes which may lie in a plane at an angle to the direction of gas flow. The electrical connection includes a circuit which adjusts the voltage between the connected adjacent electrodes to insure that the Hall voltage differential between the discrete electrodes which are adjacent to each other in the same wall of the duct does not exceed the damaging breakdown voltage. Indicator means when coupled to the circuits in accordance with the invention comprise diagnostic means which provide a graphic representation of voltage distribution along the length of the generator duct.

摘要： An electrodeless magnetohydrodynamic generator utilizes a stream of plasma pulses. The train of plasma pulses is caused to flow along an electrically insulated channel in the generator. Within the channel is established a magnetic field shaped to provide a component that is radial with respect to the longitudinal flow of the plasma. The plasma interacts with the shaped magnetic field to establish a pulsating magnetic field in the generator channel. A multi-turn coil is inductively coupled to the pulsating magnetic field and obtains AC power as the output of the generator.
