Einrichtung zur Verbesserung des Wirkungsgrades von WasserzehtralheizungenDevice to improve the efficiency of water central heating
Die Erfindung bezieht sich auf eine Einrichtung, mit deren Hilfe es möglich ist, den Wirkungsgrad von Wasserzentralheizungsanlagen wesentlich zu erhöhen, Heizungskosten zu senken und dadurch das Heizen umweltfreundlicher zu machen.The invention relates to a device with the help of which it is possible to increase the efficiency of water central heating systems to increase significantly, to reduce heating costs and thereby to make heating more environmentally friendly.
Um beim Heizen in Zentralheizungsanlagen möglichst hohe Wirkungsgrade zu erreichen, hat man bisher bei den Brenninstrumenten für optimale Verbrennung des Brennmaterials gesorgt, die Anlagen gut isoliert und im Wärmetauscher günstige Wärmeübergangsverhältnisse und eine hohe Ausnutzung der Verbrennungswärme angestrebt. Letzteres geschieht jedoch bisher nur unvdill ständig, weil die Bauverhältnisse starr, die Betriebsverhältnisse jedoch sehr unterschiedlich sind.In order to achieve the highest possible efficiency when heating in central heating systems To achieve this, the burning instruments have so far ensured optimal combustion of the fuel, the systems are good insulated and in the heat exchanger favorable heat transfer conditions and a high utilization of the heat of combustion aimed at. The latter However, so far has only happened unfairly, because the structural conditions are rigid, but the operating conditions are very different are.
Die Betriebsverhältnisse im Wärmetauscher werden hauptsächlich durch den eingestellten Wassertemperaturbereich, den Verrußungsgrad und die Paktoren des erhitzten Gasgemisches wie Temperatur und Strömungsgeschwindigkeit beeinflußt, welche teils unterschiedlich eingestellt werden, teils während des Betriebes erheblich schwanken. Daraus folgt, daß eine unveränderliche Konstruktion nicht immer optimale Ausnutzung bieten kann, die aber durch die gestiegenen Energiekosten und die steigenden Anforderungen des Umweltschutzes dringend geboten ist.The operating conditions in the heat exchanger are mainly due to the set water temperature range, the degree of sooting and the factors of the heated gas mixture such as temperature and flow rate influences which are partly set differently, partly fluctuate considerably during operation. From it it follows that an unchangeable construction can not always offer optimal utilization, but this is due to the increased energy costs and the increasing demands of environmental protection are urgently needed.
Behördlich ist vorgeschrieben, daß die Abgastemperatur den Mindestwert von 180 C nicht unterschreiten darf, um zu gewährleisten, daß sich aus dem austretenden Abgas keine schädlichen Kondensate im Kamin absetzen.It is officially prescribed that the exhaust gas temperature is the minimum value should not fall below 180 C to ensure that no harmful condensates form in the chimney from the exhaust gas drop.
Aufgabe der Erfindung ist es, zu erreichen, daß dem Abgas unter allen im normalen Betrieb auftretenden Bedingungen die Wärme bis zum zulässigen Wert entzogen wird.The object of the invention is to achieve that the exhaust gas among all the conditions occurring during normal operation, the heat is extracted up to the permissible value.
Zur Lösung dieser Aufgabe werden erfindungsgemäß folgende Vorschläge gemacht:In order to achieve this object, the following proposals are made according to the invention made:
1) Mittels eines Meßfühlers im Abgasrohr wird die Strömungsgeschwindigkeit der Heizgase im Wärmetauscher geregelt1) The flow velocity is measured by means of a sensor in the exhaust pipe the heating gases are regulated in the heat exchanger
2) Mittels eines Meßfühlers im Abgasrohr wird ein zusätzlicher Wärmetauscher je nach Bedarf zu- oder abgeschaltet.2) An additional heat exchanger is created by means of a sensor in the exhaust pipe switched on or off as required.
Die Erfindung ist an Hand von zwei Zeichnungen näher erläutert. Es stellen dar:The invention is explained in more detail with reference to two drawings. They represent:

Fig. 1 einen schematisch dargestellten Schnitt durch eine Kesselanlage mit eingebauter Einrichtung nach Vorschlag 1)1 shows a schematically illustrated section through a boiler system with built-in device according to suggestion 1)
Fig. 2 einen schematisch dargestellten Schnitt durch eine Kesselanlage mit eingebauter Einrichtung nach Vorschlag 2)Fig. 2 is a schematically illustrated section through a boiler system with built-in device according to suggestion 2)
In beiden Darstellungen sind die mit Wasser gefüllten Räume der Wärmetauscher schraffiwrt dargestellt.In both representations, the water-filled spaces of the heat exchangers are shown hatched.
Im Ausführungsbeispiel nach Vorschlag 1) (Fig. 1) wird zur Temperaturmessung des Abgases und als Stellmotor ein kleiner Hydraulikzylinder (2), der mit einem mit einer wärmebeständigen Flüssigkeit gefüllten Meßrohr (1) verbunden ist, verwendet. Über einen Hebel (3) mit der Klappe (4) wird der Öffnungsquerschnitt des oberen Wärmetauscherrohres (5) geregelt. Liegen mehrere Wärmetauscherrohre nebeneinander, wie es vielfach üblich ist, kann auch mit einer entsprechenden Rohrgruppe auf diese Art geregelt werden. Zur Einstellung der gewünschten Abgastemperatur ist der Hydraulikzylinder längenverstellbar ausgeführt. Voraussetzung für die wirkungsvolle Funktion einer solchen Einrichtung ist, daß die Kapazität des Wärmetauschers so bemessen ist, daß über den durchschnittlich benötigten Bedarf hinaus eine Kapazitätsreserve zur Regelung frei ist.In the exemplary embodiment according to proposal 1) (Fig. 1), the temperature measurement of the exhaust gas and a small hydraulic cylinder (2) as a servomotor, which is connected to a heat-resistant liquid filled measuring tube (1) is connected, used. A lever (3) with the flap (4) is used to set the cross-section of the opening of the upper heat exchanger pipe (5) regulated. If several heat exchanger tubes are next to each other, as is often the case, a corresponding one can also be used Pipe group can be regulated in this way. The hydraulic cylinder is used to set the desired exhaust gas temperature designed to be adjustable in length. A prerequisite for the effective function of such a device is that the capacity of the heat exchanger is dimensioned in such a way that there is a reserve capacity for regulation beyond the average required requirement free is.
Ist das nicht der Fall, kann ein entsprechender Effekt analog dem Ausführungsbeispiel (2) erzielt werden, was in der Regel für den nachträglichen Einbau in bestehende Anlagen der FaIl sein dürfte. la.zu wird in das Abgasrohr ein zusätzlicher Wärmetauscher (7) mit einer zu diesem parallel geschalteten Abgasleitung (6) eingesetzt. Mit der Klappe (8), die auf die im Ausführungsbeispiel 1 geschilderte Art von einem kleinen Hydraulikzylinder (2) betätigt wird, wird nun je nach Bedarf ein Teil des Abgases durch den Wärmetauscher (7) und der Rest durch die Abgasleitung (6) geführt, sodaß nach dem Zusammenführen der beiden Abgasströme die passende Mischungstemperatur entsteht.If this is not the case, a corresponding effect can be achieved analogously to the exemplary embodiment (2) can be achieved, which should usually be the case for subsequent installation in existing systems. la. to an additional heat exchanger (7) with a used in parallel to this exhaust pipe (6). With the flap (8), which is based on the one described in embodiment 1 Operated by a small hydraulic cylinder (2), part of the exhaust gas is now fed through the heat exchanger (7) as required and the remainder is passed through the exhaust pipe (6), so that the appropriate mixture temperature after the merging of the two exhaust gas flows arises.
Zur korrekten Temperaturaufnahme ist das Messrohr in Strömungsrichtung hinter der Klappe im Abgasrohr (9) angebracht.For correct temperature recording, the measuring tube is in the direction of flow mounted behind the flap in the exhaust pipe (9).
Erfindungsgemäß kann die durch den Hydraulikzylinder (1) mit dem Meßrohr übernommene Funktion auch durch ein Temperaturmeßgerät und einem Stellmotor ähnlich den im Heizungsbau seit langem üblichen Mischer-Stellmotoren und Thermostaten übernommen werden.According to the invention, the function assumed by the hydraulic cylinder (1) with the measuring tube can also be performed by a temperature measuring device and a servomotor similar to the mixer servomotors and thermostats that have long been used in heating engineering.
