Description

Hochdruckdampfkessel mit mittelbarer Beheizung- durch umlaufenden überhitzten Dampf 4 von geringerer als der im Verdampfer erzeugten Spannung Die Erfindung betrifft eine Einrichtung für Hochdruckdampfkessel mit umlaufendem Dampf, der durch das in einem Verdampfer befindliche Wasser geleitet wird. Derartige Anlagen erfordern zur Überwindung der Strömungswiderstände eine Pumpe, die den im Verdampfer entstehenden Dampf ansaugt und durch einen Überhitzer drückt. Eine solche Pumpe bedeutet-stets eine Gefahr für den Betrieb solcher Kesselanlagen, da die Stopfbüchse .der Pumpe oft gegen mehr als i (-io Ätm.Diuclcunterschied bei einer Temperatur von mehr als 300'.-abzudichten hat. ;Im übrigen bedeutet eine Störung im Antrieb der Pumpe einen Betriebsstillstand für die ganze Anlage. Auch erhöhen die Betriebskosten der Pumpenanlage die Kosten des Betriebes der ganzen Kesselanlage nicht unwesentlich. Es ist bereits ein Verfahren bekannt geworden, bei dem durch den einem Hochdruckkessel entnommenen Dampf mittels, Strahlgebläses ein Gas von niederer Spannung angesaugt wird und das Gemisch auf den Wasserinhalt eines Niederdxuckkessels erhitzend wirkt; doch bezweckt dieses Verfahren lediglich die Erzielung einer Wärmeregelung für den Hochdruckkessel.High-pressure steam boiler with indirect heating by circulating superheated steam 4 of less than the voltage generated in the evaporator. The invention relates to a device for high-pressure steam boilers with circulating steam which is passed through the water in an evaporator. Such systems require a pump to overcome the flow resistance, which sucks in the vapor generated in the evaporator and pushes it through a superheater. Such a pump always means a danger for the operation of such boiler systems, since the stuffing box of the pump often has to be sealed against more than 1 (-io atmospheric pressure difference at a temperature of more than 300 '-.; Otherwise, it means a malfunction In the drive of the pump a standstill for the entire system. The operating costs of the pump system also increase the costs of the operation of the entire boiler system not insignificantly Voltage is sucked in and the mixture has a heating effect on the water content of a low-pressure boiler; however, this method only aims to achieve heat control for the high-pressure boiler.

Die Erfindung besteht nun darin, da.ß an einem Hochdruckdampfkessel mit mittelbarer Beheizung durch umlaufenden überhitzten Dampf von geringerer als der im Verdampfer erzeugten Spannung eine durch den Verdampfer geführte Rohrschlange über eine an den Verdampfer angeschlossene und den Umlauf bewirkende Dampfmischv orrichtung mit dem Überhitzer zu einer Kreisleitung verbunden ist, welcher der Verbrauchsdampf entnommen wird.The invention consists in the fact that a high-pressure steam boiler with indirect heating by circulating superheated steam of less than the voltage generated in the evaporator is a coil guided through the evaporator Via a steam mixer connected to the evaporator and causing the circulation device is connected to the superheater to a circuit line, which the consumption steam is removed.

Sie hat den Vorteil, den Umlauf des Dampfes in einer Hochdruckdampfer zeugungsanlage ohne Pumpe zu bewerkstelligen. Bei dieser Anlage gibt der durch den Verdampfer geführte Heißdampf dort seine Überhitzungswärme ab. Durch Umsetzung der Druckenergie beim Zusammentreffen des im Verdampfer entstehenden höher gespannten Dampfes mit dem umlaufenden Dampf entsteht in der Mischdüse eine Strömungsenergie, die zur Überwindung der Strömungswiderstände in der Kreisleitung benutzt wird.It has the advantage of circulating the steam in a high pressure steamer generating plant without a pump. With this system, the Evaporator discharged superheated steam there from its superheating. By implementing the Pressure energy when the higher tension generated in the evaporator meets Steam with the circulating steam creates flow energy in the mixing nozzle, which is used to overcome the flow resistance in the circuit line.

Ein Dampfkessel nach der Erfindung ist in der Zeichnung beispielsweise dargestellt, und zwar zeigt die Abb. i eine Darstellung des ganzen Kessels. a ist der Verdampfer mit der Rohrschlange b, c ist der Überhitzer, d die Mischdüse, bei e strömt der erzeugte Dampf-' zur Verbrauchsstelle. Bei f wird der erzeugte Dampf dein Verdampfer entnommen und durch eine Leitung, in die der Dampfbehälter g- eingeschaltet ist, der Mischdüse zugeführt. h ist ein Vorwärmer für das Speisewasser, das von der Speisepumpe i in den Verdampfer gefördert wird.A steam boiler according to the invention is shown in the drawing, for example shown, namely the Fig. i shows a representation of the entire boiler. a is the evaporator with the coil b, c is the superheater, d the mixing nozzle, at The generated steam flows to the point of consumption. At f is the generated steam Your vaporizer is removed and switched through a line into which the vaporizer g- is fed to the mixing nozzle. h is a preheater for the feed water from the feed pump i is fed into the evaporator.

Die Abb. z und 3 zeigen Ausführungsformen der Mischdüse d. Der vom Dampfbehälter g kommende hochgespannte Sattdampf tritt durch die Mündung h in den Mischraum und reißt aus der Leitung b den abgekühlten Dampf niedrigerer Spannung mit, um ihn im Diffusor l unter Geschwindigkeitsverringerung auf den mittleren Druck zu bringen, der im Überhitzer c und in der Verbrauchsleitung e verlangt wird.Figs. Z and 3 show embodiments of the mixing nozzle d. The from High-tension saturated steam coming from the steam tank g enters the through the mouth h Mixing space and tears the cooled steam of lower voltage from line b with to it in the diffuser l while reducing speed to the medium pressure to bring, which is required in the superheater c and in the consumption line e.
