An MHD stand-alone high efficiency power generation method comprises following three steps; a thermo-chemical coal gasification step in which waste heat of exhaust gas from an MHD generator 1b of an MHD power generation apparatus 1 is converted into chemical energy of coal syngas by a coal gasification process in the furnace 2; a pre-heating step in which the waste heat of the exhaust gas through the coal gasification furnace 2 is recovered as a sensible heat of a coal syngas and hydrogen mixture by heat exchange in the pre-heater 3; and an iodine - sulfur reaction step in which the waste heat of the exhaust gas through the fuel pre-heater is converted into hydrogen energy by splitting water in the IS system 4. By means of the said three steps, the high temperature waste heat from the MHD generator 1b is regenerated as the sensible heat of the fuel mixture and the fuel chemical energy. The method further comprises a step in which the regenerated energy is re-circulated to a combustor 1a of the MHD power generation apparatus 1, and the fuel consisting of the syngas produced in the gasification furnace and the hydrogen produced in the iodine - sulfur unit is combusted with pure oxygen. As a result, a high efficiency power generation system with no carbon dioxide emission capability can be designed by using an MHD stand-alone unit, and using coal resource as the primary fuel.
摘要:
A magnetohydrodynamic electric generator is disclosed, which is so devised that the coherent light generated in it by electrical stimulation, heat induction and/or gas expansion is collected and focused towards the gas plasma moving between the magnets and the electricity-collecting plates. In this generator, the composition of the laser gas mixture is also controlled and adjusted to compensate for the unavoidable loss occurring in operation, when some of the gas molecules, especially CO2, are dissociated.

Process for producing a plasma by heating a gas flow, and a magnetohydrodynamic converter to implement the process, in order to produce electrical energy at low coast. For this purpose, at least two gas flows are created in a hollow flow body (1), which move rotationally and in the same direction of rotation around the stray field lines of an external axial magnetic field and which are directed towards one another in such a way as to meet in the central area of the hollow flow body and to form there a centre of eddy currents where they are heated by an initial ignition in such a manner as to produce, in accordance with the magnetohydrodynamic principle, electric energy which provides a self-organized heating and post-heating of the gases, the Hall current formed producing in the heated gas magnetic fields which are parallel to the axis and leading, as a result of the pinch effect, to compression and the further heating of the gas in order to produce a plasma or a hot plasma. The magnetohydrodynamic converter designed to produce this process consists essentially of a hollow flow body (1) with a great number of flow channels (2) directed toward one another, which are arranged in proximity to magnets (8) and possess tangential gas lines (11) to produce rotational flows.

A force (F, P) acting on the liquid metal (7) flow is increased and decreased by the interaction between the magnetic field (8) and the electric current (11). An apparatus for preforming the method comprising material (10) varying in electric property with the temperature of the liquid metal (7). The material is in at least one of a path of the magnetic field (8), a path of the electric current (11) and means for generating the magnetic field. Variation of the electric property of the material allows one of the magnetic field (8) and the electric current (11) to be automatically increased or decreased in intensity in response to the temperature of the liquid metal (7), so that the force (F, P) acting on the liquid metal flow (7) is controlled.
