Abstract:
The purpose of the present invention is to provide new renewable energy by utilizing aluminum, which is easy to store and is stably suppliable, as a fuel without harming the environment or the human body. An aluminum powder and oxygen are introduced into a combustion chamber and subjected to stationary combustion, and the generated energy is taken out and utilized. The stationary combustion of aluminum is conducted by controlling either or both of the amounts of the aluminum powder and oxygen which are to be introduced into the combustion chamber. The control of the amount of the aluminum powder is accomplished by controlling the amount of the aluminum powder to be sucked into a jet stream of a carrier gas for introducing the powder into the combustion chamber or by controlling the amount of an impurity to be mixed with the aluminum powder. The control of the amount of the oxygen is accomplished by controlling the mixing ratio of the amount thereof to the amount of a diluent gas to be introduced simultaneously. The alumina resulting from the combustion is recovered, and aluminum obtained by reducing the alumina can be recycled as a fuel.
Abstract:
Die Erfindung betrifft eine Stoffverwertung mit elektropositivem Metall. Diese kann vorteilhaft als Post-Oxyfuel-Prozess für Oxyfuel-Kraftwerke eingesetzt werden. Dabei wird durch die erfindungsgemäße Stoffverwertung ein Energiekreislauf realisiert. Ein elektropositives Metall, insbesondere Lithium, dient als Energiespeicher sowie als zentrales Reaktionsedukt für die Umsetzung von Stickstoff und Kohlendioxid in Ammoniak und Methanol. Das erfindungsgemäße Kraftwerk arbeitet so CO 2 -emmisionsfrei.
