Description

Im Patent 941:291 ist ein Zwangstrom-Röhrendampferzeuger mit Temperaturregelung des Heißdampfes durch Wassereinspritzung im Überhitzer beschrieben, bei dem der Überhitzer an der Einspritzstelle in zwei Abteilungen aufgeteilt und zwischen diesen; beiden Abteilungen eine Heizfläche eingeschaltet ist, die in einem Temperaturgebiet liegen soll, das wesentlich niedriger als das Temperaturgebiet dies Überhitzers ist.Patent 941: 291 describes a forced-flow tubular steam generator with temperature control of the superheated steam described by water injection in the superheater, in which the Superheater at the injection point divided into two compartments and between them; a heating surface is switched on in both departments, which is in a temperature range should lie, which is much lower than the temperature range of this superheater is.

Die, Erfindung betrifft eine Weiterbildung dieser Anordnung, und zwar geht sie von einem Zwangstrom-Röhrend'ampferzeuger aus, bei dem der letzte Teil der Verdampfungszone in einem milderen Temperaturgebiet als der erste Teil der Verdampfusngszome liegt. Der hinter der Wassereinspritzstelle liegende zusätzliche Heizflächenteil soll gemäß der Erfindung in der gleichen Wärmezone wie der letzte Teil der Verdampfungsheizfläche liegen.The invention relates to a development of this arrangement, namely it assumes a forced current tubular steam generator, in which the last part the evaporation zone in a milder temperature area than the first part of the evaporation zone lies. The additional heating surface part behind the water injection point should according to the invention in the same heating zone as the last part of the evaporation heating surface lie.

Die Anordnung ist in der Abbildung dargestellt. Der Dampferzeuger, der durch eine Feuerung i beheizt wird, ist durch eine Zwischenwand 2 in den Strahlungsteil 3 und in den Berührungsteil4 unterteilt. Die Heizgase strömen in Richtung der Pfeile 5 aus dem Strahlungsteil in den Berührungsteil. Dias Arbeitsmittel wird durch. eine Pumpe 6 zunächst dem im Strahlungsteil liegenden Voerwärmer 7 und anschließend der Heizfläche 8 zugeführt, die den ersten Teil der Verdampfungszone enthält. Nach Durchströmen dieses Heizflächenteiles gelangt das Arbeitsmittel in die in einem milderen Temperaturgehiet liegende zweite Zone derVerdampfung, wird hier, vollständig inDampf umgewandelt und in dem Heizflächenteil io leicht überhitzt. Die Temperatur des Arbeitsmittels wird dann in dem Heizflächenteil i i weitergesteigert. Hinter diesem Heizflächenteil ist die Vorrichtung 13 zur Temperaturregelung durch Wassereinspritzung eingeschaltet. Die Wassereinspritzung ist mit i9 bezeichnet. Die Endüberhitzung des Arbeitsmittels erfolgt im Heizflächenteil 1a. Die nach dem Hauptpatent zwischen die Überhitzerteile i i und 12 eingeschaltete zusätzliche Heizfläche 15 ist nun gemäß der Erfindung im wesentlichem in dasselbe Temperaturgebiet verlegt wie der Heizflächenteil9, also wie die letzte Veerdampfungszone. Der Vorteil dieser Anordnung ist der, daß in dem Heizflächenteil 15 annähernd die gleichen Wärmeverhältnisse wie in Teil 9 herrschen, so, da.ß also die Vorteile, die sich aus der Anordnung der Heizflächenteile 9 ergeben, auch der zusätzlichen Heizfläche 15 zugute kommen. Die beiden Heizflächenteile 9 und 15 können ineinandergew'iclcelt oder ineinandergeschachtelt sein.The arrangement is shown in the picture. The steam generator, which is heated by a furnace i is through a partition 2 in the radiation part 3 and divided into the touch part 4. The heating gases flow in the direction of the arrows 5 from the radiation part into the contact part. The work equipment is through. one Pump 6 first the pre-heater 7 located in the radiation part and then the Heating surface 8 supplied, which contains the first part of the evaporation zone. After flowing through This part of the heating surface is where the working fluid reaches a milder temperature lying second zone of evaporation, is here, completely converted into steam and slightly overheated in the heating surface part. The temperature of the working medium is then increased further in the heating surface part i i. Behind this part of the heating surface the device 13 for temperature control by water injection is switched on. The water injection is labeled i9. The final overheating of the working medium takes place in the heating surface part 1a. The one according to the main patent between the superheater parts i i and 12 switched on additional heating surface 15 is now according to the invention essentially in the same temperature range as the heating surface part9, i.e. like the last evaporation zone. The advantage of this arrangement is that in the Heating surface part 15 has almost the same heat conditions as in part 9, so, da.ß the advantages resulting from the arrangement of the heating surface parts 9, the additional heating surface 15 also benefit. The two heating surface parts 9 and 15 can be interleaved or nested.

Für die Einspritzregelung ist eine Impulsregelung 14 vorgesehen.A pulse control 14 is provided for the injection control.
