Abstract

Der Einspritzkühler zur Temperaturregelung von überhitztem Dampf besitzt eine an einem Dampfrohr (1) festlegbare Kühlwasser-Zuführarmatur (2) und ein davon abgehendes und in das Dampfrohr (1) hineinragendes Düsenrohr (3).
Die Zuführarmatur (2) beinhaltet ein den Wasserdruck (P2) im Düsenrohr (3) einstellendes Regelventil (4) und das Düsenrohr (3) weist mindestens eine sich in Abhängigkeit vom Wasser- und Dampfdruck (P2,P1) einstellende Düse (5) auf.The injection cooler for controlling the temperature of superheated steam has a cooling water supply fitting (2) which can be fixed to a steam pipe (1) and a nozzle pipe (3) going out and projecting into the steam pipe (1).
The feed fitting (2) contains a control valve (4) that adjusts the water pressure (P2) in the nozzle tube (3), and the nozzle tube (3) has at least one nozzle (5) that is adjusted depending on the water and steam pressure (P2, P1) .

Die Düse (5) oder Düsen (5) sind im Düsenrohr (3) quer zur Längsrichtung des Düsenrohres (3) und in Längsrichtung des Dampfrohres (1) angeordnet.

Figure 00000001
The nozzle (5) or nozzles (5) are arranged in the nozzle tube (3) transversely to the longitudinal direction of the nozzle tube (3) and in the longitudinal direction of the steam tube (1).
