Abstract

The invention defines a multi-unit district heating power station (MDHPS) having a novel assembly of components such that the previously customary additional fossil-fuel burner for the heating circuit is replaced by an electrical resistance-type solid-state accumulator. In this case, the invention provides that the accumulator is fed from the generators of the MDHPS. The patent application also covers using a heat pump to include in the heating circuit the radiator heat transfer losses of the solid state accumulator.

Description

Blockheizkraftwerke (BHKW) als Ersatz für die Fernenergieversor­ gung haben bisher in Erfüllung ihrer dezentralen Aufgaben für die Kraft-Wärme-Koppelung einen Anteil der Wärmeerzeugung mit­ tels Fossilbrenner, der heute noch zwischen 30 und 70% der Ge­ samtleistung des BHKW liegt.Combined heat and power plants (CHP) as a replacement for the remote energy supplier have so far been fulfilling their decentralized tasks for the cogeneration with a share of heat generation fossil burner, which is still between 30 and 70% of Ge total output of the CHP is.

Je nach Entwicklungsstand der verwendeten Brenner ist dieser noch mit einem sehr schlechten Wirkungsgrad behaftet, der sich ungün­ stig auf den Gesamtwirkungsgrad des BHKW auswirken kann; denn der Einzelwirkungsgrad addiert sich anteilmäßig zum Gesamtwirkungsgrad. Es ist zwar bekannt, daß in letzter Zeit durch Verbesserung der verbrennungstechnischen Regelung z.B. die Ölbrenner durch starke Absenkung der Abgastemperaturen ("Kondensationsbrenner") im Wir­ kungsgrad verbessert werden konnten, jedoch ist dies noch nicht Stand der Technik und mit Regelungs- und Wartungsproblemen behaftet.Depending on the level of development of the burners used, this is still has a very poor efficiency, which is unsuitable can have a significant impact on the overall efficiency of the CHP; because the Individual efficiency is proportionally added to the overall efficiency. It is known that lately by improving the combustion control e.g. the oil burners by strong Lowering the exhaust gas temperatures ("condensation burner") in the Wir efficiency could be improved, but this is not yet State of the art and with control and maintenance problems.

Die Erfindung betrifft deshalb eine neue Ausführungsform eines BHKW-Types, der vollkommen ohne Fossilbrenner ausgelegt ist. Der Entwicklungs- und Serienproduktionsstand der Gas- und Dieselmo­ toren zum Generatorbetrieb ist heute so hoch, daß hierbei eine leichte Erhöhung des Generatorbetriebs genügt, um den Wärmeanteil des Brenners durch eine elektrische Widerstandsheizung (Feststoff­ speicher) zu ersetzen. Die dazu notwendige Vergrößerung des Genera­ torbetriebs ist jedoch wesentlich kleiner als die zu ersetzende Heizkesselleistung, da bei der Erhöhung der elektrischen Leistung am Generator des BHKW die Vergrößerung der Kühlwasserleistung aus dem Motorblock sowie die Abgaswärme der Verbrennungsluft schon die Wärmeleistung zu Heizzwecken erhöht.The invention therefore relates to a new embodiment of a CHP types that are designed completely without fossil burners. The Development and series production status of gas and diesel engines gates to generator operation is so high today that one a slight increase in generator operation is sufficient to reduce the amount of heat the burner by an electrical resistance heater (solid memory) to replace. The necessary enlargement of the genera door operation is, however, much smaller than that to be replaced Boiler power because of the increase in electrical power on the generator of the cogeneration unit increases the cooling water output the engine block and the exhaust gas heat of the combustion air increases the heat output for heating purposes.

Bei dem erfindungsgemäßen Einsatz des strombeheizten Feststoffspei­ chers wird das Keramikmaterial auf ca. 600 Grad Celsius oder höher im Umluftbetrieb erhitzt und nach außen isoliert, wobei ein Wasser- Luft-Wärmetauscher innerhalb der Isolationszone die Heizwärme nach außen zur weiteren Verwendung (z.B. Gebäudeheizung) bringt. Die Wärme, durchgangsverluste des Feststoffspeichers werden nun in weiterer Ausgestaltung der Erfindung dadurch in den Heizkreislauf zurückgeführt daß im gleichen Raum, in dem sich der Feststoffwärmespeicher befin­ det, ein Verdampfer einer Wärmepumpe angebracht ist, der die durch die Isolation des Speichers hindurchgehende Wärmeleistung mittels den übrigen Teilen der Zusatzwärmepumpe des BHKW in den Heizkreis­ lauf zusätzlich zuführt. Dabei ist von Vorteil, daß das Verdamp­ fungsniveau des Arbeitsmediums der Wärmepumpe auf ein Niveau ein­ gestellt werden kann, welches einen Wirkungsgrad der Wärmepumpe von über 3 garantiert. Dies ist z.B. dann der Fall, wenn diese Ver­ dampfungstemperatur erfindungsgemäß nicht tiefer als 15 Grad Celsius eingestellt wird.When using the current-heated solid fuel chers the ceramic material to about 600 degrees Celsius or higher heated in recirculation mode and insulated from the outside, with a water Air heat exchanger within the insulation zone after the heating outside for further use (e.g. building heating). The heat, Continuous losses in the solids storage are now further Embodiment of the invention thereby returned to the heating circuit that in the same room in which the solid heat storage is located det, an evaporator of a heat pump is attached, which by the the insulation of the storage tank by means of heat output the remaining parts of the additional heat pump of the CHP in the heating circuit additional feed. It is advantageous that the evaporator level of the working medium of the heat pump to a level can be put, which is an efficiency of the heat pump guaranteed of over 3. This is e.g. then the case when this ver steaming temperature according to the invention not lower than 15 degrees Celsius is set.
