摘要:
A dispatchable storage combined cycle power plant comprises a combustion turbine generator, a steam power system, a heat source other than the combustion turbine generator, and a thermal energy storage system. Heat from the heat source, from the thermal energy storage system, or from the heat source and the thermal energy storage system is used to generate steam in the steam power system. Heat from the combustion turbine may be used in series with or in parallel with the thermal energy storage system and/or the heat source to generate the steam, and additionally to super heat the steam.
摘要:
Die vorliegende Erfindung betrifft eine Kraft-Wärme-Kopplungsanordnung (100), welche eine Gasturbinenanlage (110) zum Erzeugen von mechanischer Leistung, eine Wärmekraftanlage (120) mit einem Wärmetauscher (121) und einer Turbine (122) und einen Verdichter (130) zum Verdichten eines Hilfsluftstroms aufweist. Der Gasturbinenanlage (110) ist ein Zuluftstrom (111) zuführbar und ein Abluftstrom (112) abführbar. Die Wärmekraftanlage (120) ist mit einem Arbeitsmedium (126) betreibbar, wobei der Wärmetauscher (121) mit der Gasturbinenanlage (110) derart gekoppelt ist, dass thermische Energie von dem Abluftstrom (112) auf das Arbeitsmedium (126) übertragbar ist, sodass die Turbine (122) mittels des Arbeitsmediums betreibbar ist. Der Verdichter (130) ist mittels der Turbine (122) antreibbar, wobei der Verdichter (130) mit der Gasturbinenanlage (110) derart gekoppelt ist, dass der verdichtete Hilfsluftstrom (131) in die Gasturbinenanlage (110) einspeisbar ist.
摘要:
A method, system, and apparatus including a compressed air energy storage (CAES) system including a compression train with a compressor path, a storage volume configured to store compressed air, a compressed air path configured to provide passage of compressed air egressing from the compression train to the storage volume, and a heat recovery system coupled to at least one of the compressor path and the compressed air path and configured to draw heat from at least one of the compressor path and the compressed air path to a first liquid. The compression train is configured to provide passage of compressed air from a first compressor to a second compressor. The heat recovery system includes a first evaporator configured to evaporate the first liquid to a first gas and a first generator configured to produce electricity based on an expansion of the first gas.
摘要:
A co-generation power station with a steam turbine (1) is suggested, the feed water preheater (28,18) of which can be deactivated during an especially highly demanded load and the feed water is preheated by means of the energy accumulated in the heat accumulator (12).
