Abstract
Description
Die Erfindung betrifft eine Dampferzeugungsanlage, insbesondere zur Erzeugung von Heizdampf, mit einem Hauptkessel und einem Reservekessel.The The invention relates to a steam generating plant, in particular for Generation of heating steam, with a main boiler and a reserve boiler.
Dampferzeugungsanlagen solcher Art, die einen z.B. mit Biomasse beheizten Hauptkessel aufweisen, benötigen einen oder mehrere, vorzugsweise mit Gas oder Öl beheizte Reservekessel, um Ausfälle oder Engpässe der Dampferzeugung durch den Hauptkessel ausgleichen zu können. Zwecks schneller Inbetriebnahme wird der Reservekessel ständig unter Verbrauch von fossilem Brennstoff auf einem gegenüber der Umgebungstemperatur erhöhten, an die Betriebstemperatur angenäherten Temperaturwert gehalten.Steam generating plants of such kind, e.g. having biomass heated main boilers, need one or more, preferably with gas or oil heated reserve boiler to losses or bottlenecks be able to compensate for the steam generation by the main boiler. For the purpose of fast commissioning, the reserve boiler is constantly under Consumption of fossil fuel on a versus the Increased ambient temperature, approximated to the operating temperature Temperature value held.
Der Erfindung liegt die Aufgabe zugrunde, eine neue, effizienter betreibbare Dampferzeugungsanlage der eingangs erwähnten Art zu schaffen.Of the Invention is based on the object, a new, more efficiently operable To create steam generating plant of the type mentioned.
Die diese Aufgabe lösende Dampferzeugungsanlage nach der Erfindung ist gekennzeichnet durch eine gesonderte, Dampf als Heizdampf verwendende Heizeinrichtung, welche das Wasser im Reservekessel auf einer gegenüber der Umgebungstemperatur erhöhten Temperatur hält.The solving this task Steam generating plant according to the invention is characterized by a separate heating device using steam as a heating steam, which the water in the reserve boiler on one opposite the Ambient temperature increased Temperature holds.
Vorteilhaft kann fossiler Brennstoff eingespart und zur Warmhaltung des Reservekessels z.B. Dampf aus dem Hauptkessel zugeführt werden.Advantageous can save fossil fuel and keep the reserve boiler warm e.g. Steam can be supplied from the main boiler.
In einer bevorzugten Ausführungsform der Erfindung weist die Heizeinrichtung eine Leitung zum Zuführen des Dampfes direkt in den Reservekessel oder/und in ein Wärme an den Reservekessel übertragendes Heizelement auf.In a preferred embodiment According to the invention, the heating device has a line for feeding the Steam directly into the reserve boiler and / or heat to the Reservoir transferring Heating element on.
Insbesondere kann die genannte Leitung in den Dampfraum des Reservekessels einmünden, wo Wärme vom Dampf in das im Reservekessel befindliche Wasser übergeht.Especially The said pipe can lead into the steam room of the reserve boiler, where heat from the Steam passes into the water in the reserve boiler.
Zur Förderung der Wärmeübertragung ist zweckmäßig eine das Wasser im Reservekessel umwälzende Einrichtung vorgesehen.to advancement the heat transfer is appropriate one the water circulating in the reserve boiler Device provided.
Diese Umwälzeinrichtung kann eine außerhalb des Reservekessels angeordnete Umwälzpumpe umfassen, die an eine Wasser aus dem Reservekessel abführende Leitung und eine das Wasser in den Dampfraum des Reservekessels zurückführende Leitung angeschlossen ist.These circulation can be an outside the reserve boiler arranged circulating pump, which to a Waste water from the reserve boiler Pipe and one the water into the steam room of the reserve boiler returning line connected.
Vorteilhaft können zur Umwälzung in einer Dampferzeugungsanlage bereits vorhandene Leitungen genutzt werden, indem die das Wasser abführende Leitung einen Abschnitt einer Abschlammleitung des Reservekessels und die das Wasser zurückführende Leitung einen Abschnitt eine Speisewasserzuführungsleitung des Reservekessels umfasst. Durch Sperrventile in der Abschlammleitung und der Speisewasserzuführungsleitung lassen sich während der Umwälzung die betreffenden Leitungsabschnitte gegen die übrigen Teile dieser Leitungen absperren.Advantageous can to the upheaval used in a steam generating plant already existing lines by laxating the water Lead a section of a drain line of the reserve boiler and the pipe returning the water a section of a feedwater supply line of the reserve tank includes. By check valves in the drain line and the feedwater supply line can be while the upheaval Shut off the relevant line sections against the remaining parts of these lines.
Der o.g. Wärmetauscher kann Bestandteil eines die Umwälzpumpe aufweisenden Umwälzkreislaufs sein.Of the above-mentioned heat exchangers can be part of a circulation pump having Umlaufkreiskreislaufs be.
