Description

Bei Dampflokomotivkesseln der Stephenson-Bauart macht es Schwierigkeiten, den Dampfdruck über 22 atü noch merklich zu steigern. Eine Erhöhung der Dampfspannung ist aber zusammen mit der Erhöhung der Überhitzungstemperatur geboten, um das Wärmegefälle zu vergrößern.In the case of steam locomotive boilers of the Stephenson design, it is difficult to increase the vapor pressure noticeably above 22 atmospheres. An increase in vapor tension however, together with the increase in the overheating temperature, it is necessary to reduce the heat gradient to enlarge.

Der bisherige Kessel der Stephenson-Bauart ist in seiner Festigkeit in seinen einzelnen Bauteilen verschieden. Die Grenze von 22 atü wird vom Stehkessel i mit der Stehbolzenversteifung gebildet, während der J.angkessel 2 höhere Dampfdrücke auszuhalten imstande ist.The previous boiler of the Stephenson type is in its strength different in its individual components. The limit of 22 atm is made by the standing boiler i formed with the stud stiffener, while the J.angkessel 2 has higher steam pressures is able to endure.

Um die Vorteile der Wärmeübertragung bei Stehbolzenkesseln mit Feuerbüchse und bei der Unterhaltung bei niedrigem Drück beizubehalten, außerdem die derzeitige Kesselkonstruktion nicht wesentlich zu ändern, wird erfindungsgemäß der Kessel durch eine Trennwand 3 zwischen Langkessel und Stehkessel geteilt. Die Stelle der Trennwand ergibt sich aus den für HD- und ND-Teil notwendigen Heizflächen, die sich wiederum aus den geforderten ND- und HD-Dampfmengen ergeben.About the advantages of heat transfer in stud-type boilers with a firebox and in low-pressure entertainment, keep the current one as well The boiler construction does not change significantly according to the invention a partition 3 divided between the long boiler and the standing boiler. The place of the partition results from the heating surfaces required for the high pressure and low pressure parts, which in turn arise result from the required low and high pressure steam volumes.

In beiden Kesselteilen wird ein verschiedener Druck gehalten: Im Stehbolzenteil i ein Druck von 5 atü bis 16 atü, je nach Betriebs- und Unterhaltungslage, im Langkessel 2 der gewünschte Hochdruck. Beide Kesselteile sind durch eine Heißwasserdruckpumpe 12 verbunden, die das in Heißwasserform zulaufende Speisewasser in den Hochdruckteil fördert.A different pressure is maintained in both boiler parts: In the stud bolt part i a pressure of 5 atü to 16 atü, depending on the operating and maintenance situation, in the long tank 2 the desired high pressure. Both boiler parts are powered by a hot water pressure pump 12 connected, which feed water flowing into the hot water form in the high pressure part promotes.

Die Zuführung des Speisewassers aus dem Kaltwasservorratsbehälter kann mittels Injektor oder Speisewasserpumpe i i über einen Vorwärmer in den Niederdruck- bzw. Hochdruckteil erfolgen. Die Wasserhaltung im ND-Teil erfolgt wegen der hohen Feuergastemperaturen von Hand: Zuführung durch Speisepumpe i i über Absperrventil 8, Entnahme durch Heißwasserdruckpumpe 12. Um zu verhindern, daß die HD-Druckpumpe 12 Heißwasser bei zu geringem Wasserstand dem ND-Teil entnimmt, wird zur Entlastung des Heizers neben einem handbedienten Absperrventil eine automatische Abschaltung, sinnbildlich dargestellt durch Schwimmerservosteuerung 9 und Absperrventil io vorgesehen.The supply of the feed water from the cold water storage tank can be injected into the low-pressure or high pressure part. The dewatering in the low pressure part takes place because of the high Flue gas temperatures by hand: Supply by feed pump i i via shut-off valve 8, withdrawal by hot water pressure pump 12. To prevent the HP pressure pump 12 Taking hot water from the low-pressure part when the water level is too low, is a relief the heater has an automatic shut-off in addition to a manually operated shut-off valve, symbolically provided by float servo control 9 and shut-off valve io.

Die Wasserhaltung im HD-Teil erfolgt wegen der geringeren Wandtemperatur automatisch: Das Zu- und Abschalten der Pumpen erfolgt wasserstandsabhängig, angedeutet in der Skizze durch Schwimmer und Servomotor 4 und Absperrventile 5.The dewatering in the high pressure part takes place because of the lower wall temperature automatic: The pumps are switched on and off depending on the water level, indicated in the sketch by the float and servo motor 4 and shut-off valves 5.

Der HD-Dampf wird durch Dampfentnahmeleitung 6 und der ND-Dampf durch Dampfentnahmeleitung 7 entnommen und getrennten Überhitzern zugeführt.The high-pressure steam is through steam extraction line 6 and the low-pressure steam Steam extraction line 7 removed and fed to separate superheaters.

Als zusätzliche Ausrüstung ist für beide Teile die nötig, die für einen Dampfkessel vorgeschrieben ist.The additional equipment required for both parts is that for a steam boiler is mandatory.
