Description
Vorrichtung zur Überhitzung von Abdampf einer Kraftmaschine. Es ist bekannt, Arbeitsdampf aus einer Zwischenstufe einer Kraftmaschine durch die Niederschlagswärme von aus einer höheren Zwischenstufe der Maschine entnommenem Dampf zu überhitzen. Diese Maßnahme hat den Zweck, die sonst durch Kondensation eintretenden Verluste an Arbeitsvermögen zu vermindern.Device for superheating exhaust steam from an engine. It is known, working steam from an intermediate stage of an engine through the heat of precipitation to superheat from steam extracted from a higher intermediate stage of the machine. The purpose of this measure is to reduce the losses that would otherwise occur due to condensation to reduce work capacity.
Nach der Erfindung soll zu Heizzwecken dienender Abdampf einer Kraftmaschine in eine Oberflächenwi;rmeaustauschvorrichtung durch Dampf aus einer höheren Stufe in für Arbeitsdampf bekannter Weise überhitzt werden. Hierbei hat aber die überhitzung nicht den Zweck der Verminderung an Arbeitsvermögen, sondern es soll dadurch die Kondensation des Dampfes in langen Zuleitungen zu den Heizvorrichtungen verhindert werden. Die Wärmeaustauschvorrichtung kann so eingerichtet sein, da13 der Dampf aus der höheren Stufe sowohl die lTberhitzungsals auch die Kondensationswärme abgibt. Man kann die Wärmeaustauschvorrichtung aber auch so einrichten, daß der Dampf aus der höheren Stufe im wesentlichen nur seine überhitzungswärme abgibt, die z. B. bei seiner Verwendung in Zellstoffkochern schädlich wirken kann.According to the invention, exhaust steam from an engine is intended for heating purposes into a surface heat exchange device by steam from a higher stage be superheated in a manner known for working steam. But this has overheating not the purpose of reducing the ability to work, but by doing so it is supposed to Prevents condensation of the steam in long supply lines to the heating devices will. The heat exchange device can be arranged in such a way that the steam gives off both the overheating and the condensation heat from the higher level. But you can also set up the heat exchange device so that the steam the higher level essentially only emits its superheating heat, which z. B. can be harmful when used in digesters.
Die Zeichnung zeigt Beispiele der Erfindung. i ist ein Dampfkessel, der seinen Dampf durch die Leitung z in eine Turbine 3 abgibt. Im Beispiel nach der Abb. i fließt der Abdampf der Turbine durch einen überhitzer 7 und bei 9 durch eine lange Dampfleitung weiter in die Heizvorrichtung. Zur überhitzung dieses Dampfes dient bei 6 aus einer höheren Stufe der Turbine abgezapfter Dampf, der sich im überhitzer 7 niederschlägt und dessen Niederschlagswasser bei i i austritt.The drawing shows examples of the invention. i is a steam boiler, which emits its steam through line z into a turbine 3. In the example after In Fig. i, the exhaust steam from the turbine flows through a superheater 7 and at 9 a long steam line further into the heater. To superheat this steam At 6, steam drawn off from a higher level of the turbine is used, which is located in the superheater 7 precipitates and its rainwater escapes at i i.
Im Beispiel nach der Abb. z ist die Turbine 3 eine Hochdruckturbine, deren Abdampf die Niederdruckturbinie ¢ speist. Der bei 5 austretende Dampf dieser Niederdruckturbine q. fließt durch die Wärmeaustauschvorrichtung 8 und in der Richtung 9 durch eine lange Dampfleitung in die Heizvorrichtung. Er wird in der Wärmeaustauschvorrichtung 8 durch den bei 6 entnommenen Abdampf der Hochdruckturbine überhitzt. Dieser Dampf fließt, nachdem er seine überhitzungswärme abgegeben hat, in der Richtung io, z. B. in einen Zellstoffkocher.In the example according to Fig. Z, the turbine 3 is a high-pressure turbine, whose exhaust steam feeds the low-pressure turbine ¢. The steam emerging at 5 this Low pressure turbine q. flows through the heat exchange device 8 and in the direction 9 through a long steam line into the heater. He is in the heat exchange device 8 overheated by the exhaust steam of the high-pressure turbine removed at 6. That steam flows, after it has given off its superheat, in the direction io, z. B. in a digester.
