Abstract
Description
Die Erfindung betrifft ein Verfahren zur Nutzung von Niedertemperatur-Energie zum Betrieb einer Wärmekraftanlage. Das Verfahren nutzt die in einem Primärprozess erzeugte mechanische Arbeitsleistung um in einem Sekundärprozess ein Gas zu verdichten und anschließend in einem Druckbehälter zu speichern. Die bei der Verdichtung anfallende Wärme wird in den Primärprozess zurückgeführt dient der Erhöhung des Wirkungsgrads.The The invention relates to a method for using low-temperature energy for the operation of a thermal power plant. The method uses the mechanical generated in a primary process Work performance to compress a gas in a secondary process and subsequently in a pressure vessel too to save. The heat generated during compression becomes the primary process returned serves the increase the efficiency.
Es ist bekannt, dass effiziente thermische Energieerzeugungsanlagen zur Stromproduktion im Bereich hoher Temperaturen betrieben werden. Abwärmenutzung im Bereich niedriger Temperaturen gilt als technisch aufwendig und unwirtschaftlich. Auch auf dem Gebiet der regenerativen Energieerzeugung ist in vielen Fällen die Wirtschaftlichkeit der Stromerzeugung fragwürdig. So haben z.B. Photovoltanik-Anlagen einen nur schlechten Wirkungsgrad von 15–20%. Da die Erzeugungskapazität von Photovotanik-Anlagen von der jeweiligen Sonneneinstrahlung abhängig ist, müssen zur Gewährleistung der Versorgungssicherheit sonnenunabhängige Ersatzkapazitäten vorgehalten werden.It is known to be efficient thermal power generation plants for power production in the high temperature range. waste heat recovery in the low temperature range is considered technically complex and uneconomical. Also in the field of regenerative energy production is in many cases the economic viability of power generation questionable. Thus, e.g. Photovoltaic systems only one poor efficiency of 15-20%. Because the generation capacity of photovoltaic systems depends on the respective solar radiation, have to to ensure the Security of supply solar-independent replacement capacities reserved become.
Eine wirtschaftliche Nutzung von z.B. Regenerativen Energien bzw. von Abwärmenutzungssystem kann erreicht werden durch einen Niedertemperaturprozess, mit verbessertem Wirkungsgrad und der Möglichkeit zur Speicherung der erzeugten Energie. Damit können regenerative Energiequellen und Abwärme wirtschaftlich genutzt werden. Der Energiespeicher macht die Stromproduktion unabhängig von der aktuellen Verfügbarkeit der Wärmequelle.A economical use of e.g. Regenerative energies or of Waste heat recovery system can be achieved by a low-temperature process, with improved Efficiency and the possibility for storing the generated energy. This can be regenerative energy sources and waste heat be used economically. The energy storage makes the power production independently from the current availability the heat source.

Das in der Verdichtungsanlage erzeugte, verdichtete Gas ist speicherbar und kann zur Abdeckung von Spitzenlastbedarf genutzt werdenOf the Invention is based on the task of developing a thermal power process, which are also operated efficiently in the low temperature range. By The coupling with a compression process can be made from the compression resulting process heat in the thermal power process be returned. The compressed gas generated in the compression plant can be stored and can be used to cover peak demand
