Abstract

The internal combustion engine (1) and steam plant has an internal combustion engine, whose exhaust gases reach to the outlet of the engine compartment at 3000 U per min or at 500 degree celcius. The heat of the exhaust gases is transferred with a heat exchanger (3) onto the steam generator (7) of a solar or hot steam engine (8). The steam generator strongly heats up and deliver optimal steam pressure and additionally the actual free of cost heat energy of the sun or the waste heat utilizes 400 degree from industrial internal combustion engine.

Description

Ein Gas- und Dampfkraftwerk (GuD) produziert elektrischen Strom mit einem hohen Wirkungsgrad indem es die Abgase einer Gasturbine über einen Wärmetauscher zur Dampferzeugung für eine Dampfturbine benutzt, beide Antriebsaggregate treiben Stromgeneratoren an.One Gas and steam power plant (GuD) produces electric power a high efficiency by the exhaust gases of a gas turbine on a heat exchangers for steam generation for a steam turbine used, both drive units drive power generators at.

Vorliegende Erfindung benutzt das Prinzip des Gas- und Dampfkraftwerks (GuD), verwendet jedoch statt einer in dieser Kraftwerkstechnologie üblichen Gasturbine einen Verbrennungsmotor, dessen Abgase bei 3000U/min bei etwa 500°C am Ausgang des Motorraums liegen.This Invention uses the principle of the gas and steam power plant (CCGT), however, instead of one common in this power plant technology Gas turbine an internal combustion engine whose exhaust gases at 3000rpm at about 500 ° C lie at the exit of the engine compartment.

Die Wärme dieser Abgase wird vermittels eines handelsüblichen Wärmetauschers auf den Dampferzeuger eines Solar- oder Abwärmedampfmotors (s. u.a. meine Patentanmeldung vom 19.12.05 Az.: 102005 060 881.7) übertragen.The Heat this Exhaust gases by means of a commercial heat exchanger on the steam generator a solar or waste heat steam engine (see, inter alia, my patent application of 19.12.05 Az .: 102005 060 881.7).

Dadurch kann die eigentlich kostenlose Energie der Sonne oder der Hochtemperaturabwärme ab 400°C aus z.B. Verbrennungsprozessen optimal mit hohem Wirkungsgrad verwertet werden.Thereby can the actually free energy of the sun or the high temperature waste heat from 400 ° C from e.g. Combustion processes are optimally utilized with high efficiency.

Das Neuartige an dieser Erfindung ist also, dass die Wärmeübertragug auf den Dampferzeuger des Solar- oder Abwärmedampfmotor weitergeleitet wird, der aufgrund eines geringen systembedingten Wärmeenergieeintrags Zusatzenergie zur Dampferzeugung benötigt.The Novelty of this invention is thus that the Wärmeübertragug is forwarded to the steam generator of the solar or waste heat steam engine, the additional energy due to a low systemic heat energy input needed for steam generation.

Im Vergleich zu einem Gas- und Dampfkraftwerk mit Wärmekoppelung von Gasturbine und Dampfturbine liegt der Vorteil vorliegender Erfindung in einem ähnlich hohen Wirkungsgrad, wobei erstere jedoch nicht die eigentlich kostenlose Ausnutzung der Wärmeenergie der Sonne oder der Hochtemperaturabwärme ab 400°C bewerkstelligen kann.in the Comparison to a gas and steam power plant with heat coupling of gas turbine and steam turbine is the advantage of the present invention in a similarly high Efficiency, although the former is not the actually free Utilization of heat energy the sun or the high-temperature waste heat from 400 ° C can accomplish.

Weitere Vorteile vorliegender Erfindung liegen in dem kostengünstigeren Gestehungspreis des Kraftwerks wegen der Verwendung von weniger aufwendig herzustellenden Verbrennungs- und Dampfmotoren anstatt von Gas- und Dampfturbinen und der möglichen kleineren Dimensionnierung, die eine dezentralere und kompaktere (und damit verlustfreiere) Gebäude- oder Fernwärmeversorgung ermöglicht.Further Advantages of the present invention are in the cheaper Cost price of the power plant because of the use of less expensive to produce combustion and steam engines instead of gas and steam turbines and the possible smaller dimensioning, the more decentralized and more compact (and thus loss-free) building or district heating supply allows.

Der in den Patentansprüchen angegebenen Erfindung liegt die Aufgabe zugrunde einen gleichwertigen elektrischen Wirkungsgrad wie beim GuD-Turbinenkraftwerk zu erreichen, kostengünstiger in den Gestehungskosten zu sein und die eigentlich kostenlose Wärmeenergie der Sonne oder der Hochtemperaturabwärme ab 400°C zu nutzen.Of the in the claims specified invention, the object is based on an equivalent to achieve electrical efficiency as in the combined cycle gas turbine power plant, cost-effective to be in the production costs and the actually free heat energy the sun or the high-temperature waste heat from 400 ° C to use.

Dieses Problem wird durch die im Patentanspruch aufgeführten Merkmale gelöst.This Problem is solved by the features listed in the claim.

Vorliegende Erfindung besteht aus einem Verbrennungsmotor (1) der einen Stromgenerator antreibt. Sein Abgas wird durch einen Plattenwärmetauscher geleitet, wodurch der Abdampf -vom Dampfmotor (8) kommend- aufgeheizt wird.The present invention consists of an internal combustion engine ( 1 ) which drives a power generator. Its exhaust gas is passed through a plate heat exchanger, whereby the exhaust steam from the steam engine ( 8th ) is heated up.

Über das Abdampfrohr (6) wird nach dem Wärmetausch der vorerhitzte Dampf in den Dampferzeuger (7) geleitet.About the exhaust pipe ( 6 ) after the heat exchange the preheated steam into the steam generator ( 7 ).

Dieser kann durch die Vorerhitzung genügend Temperatur und Druck erzeugen, um den Dampfmotor über die Drehflügelkolben (10) optimal in Umdrehung zu halten.This can generate enough temperature and pressure by the preheating to the steam engine via the rotary vane ( 10 ) optimally in rotation.

Diese kinetische Energie wird über die Antiebsachse vom Dampfmotor (14) auf den 2. Stromgenerator (13) übertragen.This kinetic energy is transmitted via the drive axis of the steam engine ( 14 ) on the 2nd power generator ( 13 ) transfer.

Der Dampfmotor ist in einen Behälter mit Kühlwasserfüllung (11) getaucht, der den Dampfmotor kühlt, damit die Energieausbeute noch höher wird.The steam engine is in a container with cooling water filling ( 11 ), which cools the steam engine so that the energy yield becomes even higher.

Die Abwärme des Kühlwassers wird über Kraftwärmekopplung für Raumheizung (12) zweckdienlich verwerted.The waste heat of the cooling water is via cogeneration for space heating ( 12 ) usefully utilized.

Die Abwärme des Kühlwassers des Verbrennungsmotors wird ebenfalls über die Kühlwasserleitung (15) der Kraftwärmekopplung zur Raumheizung zugeführt.The waste heat of the cooling water of the internal combustion engine is also via the cooling water line ( 15 ) of the combined heat and power for space heating.
