Description

Vorrichtung zum Regeln der Dampferzeugung in Kesseln. Zur Regelung der Dampferzeugung in Dampfkesseln und anderen Dampferzeugern hat man bereits Meßinstrumente, sei es für den Dampfdruck, sei es für die Dampfgeschwindigkeit oder den Wasserstand, benutzt, die mit einem elektrischen Widerstand so in Verbindung gebracht waren, daß die Veränderung an dem Instrument eine Zu- oder Abschaltung von Widerstand und damit eine Regelung der Beschickungsvorrichtung für die Feuerung herbeiführten.Device for regulating the generation of steam in boilers. Regarding the regulation the steam generation in steam boilers and other steam generators one already has measuring instruments, be it for the steam pressure, be it for the steam speed or the water level, used, which were so associated with an electrical resistance, that the change to the instrument is a connection or disconnection of resistance and thus brought about a regulation of the charging device for the furnace.

Um nun eine höchstmögliche Gleichförmigkeit in dem Betrieb des Dampfkessels zu sichern, sind gemäß der Erfindung die hekannten Meßinstrumente für Wasserstand, Dampfdruck, Dampftemperatur und Dampfdurchgang mit je einem elektrischen Widerstand verbunden und alle Einzelwiderständedurch Hintereinanderschaltung zu einem Gesamtwiderstande zusammengeschlossen, dessen Ohmsch ie Größe von allen Einzelwiderständen und damit von allem. Einzelwiderständen der gemessenen. Medien abhängig ist. In einen. Stromkreis mit konstanter Stromquelle eingeschaltet, verändert dieser Gesamtwiderstand bei Veränderungen an einem oder mehreren Instrumenten nach dem Ohmschen Gesetz die Stromstärke. Dieser Strom wird unmittelbar oder mittelbar über Relais, oder Kathodenröhren zur Regelung der Brennstoffzufuhr benutzt. Es könnte z. B. die Umldrehungszahl des Antriebsmotors eines Wanderrostes oder das Zuführungsorgan einer Kohlenstaub- oder Ölfeuerung damit beeinflußt werden.In order to achieve the highest possible uniformity in the operation of the steam boiler to secure are known according to the invention Measuring instruments for water level, steam pressure, steam temperature and steam passage with one electric each Resistor connected and all individual resistors connected in series a total resistance, the ohmic size of which is the same as that of all individual resistances and thus of everything. Individual resistances of the measured. Media is dependent. In a. Circuit switched on with constant current source, changes this total resistance in the case of changes to one or more instruments according to Ohm's law, the Amperage. This current is transmitted directly or indirectly via relays or cathode tubes used to regulate the fuel supply. It could e.g. B. the number of revolutions of the Drive motor of a traveling grate or the feed member of a pulverized coal or Oil firing can thus be influenced.

In der Zeichnung ist das Schema einer solchen Schaltung unter Fortlassung aller als bekannt vorauszusetzenden Einzelheiten dargestellt.The diagram of such a circuit is omitted in the drawing all details that are assumed to be known are shown.

Mit den Meßinstrumenten,-a für die Dampfentnahme, b für die Dampftemperatur, c für den Dampfdruck und d für den Wasserstand, sind einzelne elektrische Widerstände verbunden, die in einem Stromkreise hintereinander zu einem Gesamtwiderstand zusammengeschlossen sind. In demselben Stromkreise ist der Antriebsmotor e irgendeiner mechanischen Brennstoffbeschickungsvorrichtüng für eine Dampfkesselfeuerung eingebaut. Die Schaltung des Motors ist so gewählt, daB Widerstandsänderungen im Stromkreise entsprechende Veränderungen der Umdreliungsgeschwindigkeit des Motors zur Folge haben; hierbei deuten die Pfeile in der Zeichnung diejenige Schaltbewegung an, welche beim Wachsen des gemessenen Mediums eintritt.With the measuring instruments, -a for the steam extraction, b for the steam temperature, c for the steam pressure and d for the water level are individual electrical resistances connected, which are connected one behind the other in a circuit to form a total resistance are. In the same circuit, the drive motor e is some mechanical one Built-in fuel feeder for a steam boiler. The circuit of the motor is selected in such a way that changes in resistance in the circuit are appropriate Result in changes in the speed of rotation of the engine; here the arrows in the drawing indicate the switching movement that occurs when growing of the measured medium enters.

Wird die Dampfentnahme aus dem Kessel plötzlich größer, so ;sinken infolgedessen Dampftemperatur, Druck und Wasserstand. Der Wärmeinhalt oder -vorrat des Dampferzeugers wird verringert. Aus der Richtung der Pfeile erkennt man, daß damit bei allen Widerständen eine Verkleinerung und infolgedessen ein Anwachsen des durchfließenden Stromes, eine Erhöhung der Umdrehungszahl des Motors und eine verstärkte Brennstoffzufuhr eintreten muß. Hierdurch steigen Druck und Temperatur wieder, ihre Meßinstrumente erhöhen die zugehörigen Widerstände usw. Auf alle diese endlosen sich gegensei;ig dem Wärmewerte nach' ergänzenden oder aufhebenden Möglichkeiten stellt sich die Brennstoffzufuhr ein.If the steam extraction from the boiler suddenly increases, so; decrease consequently steam temperature, pressure and water level. The heat content or supply of the steam generator is reduced. From the direction of the arrows you can see that thus a reduction in size and consequently an increase in all resistances of the flowing current, an increase in the number of revolutions of the motor and a increased fuel supply must occur. This increases pressure and temperature again, their gauges increase the associated resistances, etc. On all of these endless possibilities which complement or cancel each other according to the heat values the fuel supply adjusts itself.
