Description

Einrichtung zum Vorwärmen von Kesselspeisewasser. Die Erfindung bezieht sich auf eine Einrichtung zum Vorwärmen des Kesselspeisewassers durch Mischen des Abdampfes der Speisewasserpumpe mit dem Speisewasser.Device for preheating boiler feed water. The invention relates on a device for preheating the boiler feed water by mixing the Evaporation of the feed water pump with the feed water.

Das Neue der Erfindung gegenüber Einrichtungen bekannter Art besteht darin, daß das Abdampfrohr zu einer mit Öffnungen versehenen, seitlich in das Saugrohr einmündenden Rohrschraube verlängert ist, die in einer gegen Wärmeausstrahlung geschützten Sammelgrube für das Speiserohr liegt.The novelty of the invention compared to devices of the known type consists in that the exhaust pipe becomes an apertured, laterally in the suction pipe opening pipe screw is extended, which is protected against heat radiation in a Collecting pit for the feed pipe is located.

Dadurch wird die Wärme des gesamten Abdampfes restlos zur Vorwärmung des Speisewassers verwendet und der Abdampf innig mit dem Speisewasser gemischt. Schädliche Wänrieverluste durch Ausstrahlen der Wärme nach außen werden vermieden.This means that the heat from the entire exhaust steam is used for preheating of the feed water is used and the exhaust steam is intimately mixed with the feed water. Harmful heat losses by radiating the heat to the outside are avoided.

Die Erfindung ist auf der Zeichnung näher veranschaulicht.The invention is illustrated in more detail in the drawing.

Die Abbildung zeigt einen teilweisen Querschnitt der Einrichtung.The figure shows a partial cross-section of the facility.

Von der Dampfkesselspeisewasserpumpe a, die den Dampfkesseln ununterbrochen das Speisewasser zuführt, wird der Abdampf zunächst durch das Rohr b in den Ölabscheider geleitet und dort von öligen Bestandteilen befreit. Das abgeschiedene Öl kann durch den Hahn c abgelassen werden.From the boiler feed water pump a, which runs the boilers continuously the feed water supplies, the exhaust steam is first through the pipe b into the oil separator guided and freed from oily components there. The separated oil can through the cock c can be drained.

Aus dem ölabscheider strömt der gereinigte Abdampf durch die Rohrleitung d in das in der Dampfkesselspeisewassergrube angeordnete, schxaubenförmxg gewundene Rohrsystem e, das mit seinem anderen Ende seitlich in das Saugrohr f der Speisewasserpumpe a einmündet.The cleaned exhaust steam flows from the oil separator through the pipeline d in the screw-shaped, coiled in the steam boiler feed water pit Pipe system e, which with its other end laterally into the suction pipe f of the feed water pump a joins.

Die Windungen des Rohrsystems e sind mit vielen kleinen Öffnungen g versehen, durch die das in der Speisewassergrube befindliche Speisewasser angesaugt wird. Als Speisewasserbehälter wird eine Sammelgrube verwendet, die das vorgewärmte Speisewasser gegen Wärmeverluste schützt.The turns of the pipe system e have many small openings g, through which the feed water in the feed water pit is sucked in will. A sump is used as the feed water tank, which holds the preheated Protects feed water against heat loss.

Durch die Verbindung der Saugerohrleitung f durch das gekühlte Rohrsystem e mit dem Abdampfrohre b wird der Abdampf aus dem Dampfzylinder der Speisewasserpumpe a niedergeschlagen, wodurch der Gegendruck auf den Dampfkolben fortfällt, mithin die Speisewasserpumpe a leichter läuft.By connecting the suction pipe f through the cooled pipe system e to the exhaust pipes b, the exhaust steam from the steam cylinder of the feed water pump a is precipitated, whereby the counter pressure on the steam piston is eliminated, and consequently the feed water pump a runs more easily.
