Abstract

Bei einem Einspritzkühler (10) zur Kühlung von in einer Rohrleitung (20) geführtem Heißdampf, mit einem zumindest abschnittsweise in der Rohrleitung (20) angeordneten Einspritzzylinder (30), der mit mehreren Einspritzdüsen (32) versehen ist, mit einem Regelorgan (50), das mit einem Anschluss (52) an eine Kühlmittelversorgung anschließbar ist, wobei in dem Regelorgan (50) eine Ventilanordnung (60) vorgesehen ist, mit der die Kühlmittelzuführung zu den Einspritzdüsen (32) im Einspritzzylinder (30) regelbar ist, und mit Kühlmittelzuführleitungen (70), die zwischen dem Einspritzzylinder (30) und dem Regelorgan (50) vorgesehen sind, wobei für jede Einspritzdüse (32) eine separate Kühlmittelzuführleitung (70) vorgesehen ist, sieht die Erfindung vor, dass die dem Einspritzzylinder (30) zugeordneten Enden (71) der Kühlmittelzuführleitungen (70) an einer gemeinsamen ersten Flanschplatte (73) befestigt sind, die an einer Aufnahmefläche (36) am Einspritzzylinder (30) fixierbar ist, und dass die dem Regelorgan (50) zugeordneten Enden (72) der Kühlmittelzuführleitungen (70) an einer gemeinsamen zweiten Flanschplatte (74) befestigt sind, die an einer Aufnahmefläche (56) des Regelorgans (50) fixierbar ist, wobei die Kühlmittelzuführleitungen (70) und die Flanschplatten (73, 74) eine Baugruppe (B) bilden, die zwischen dem Einspritzkühler (30) und dem Regelorgan (50) montierbar ist. Der der Einspritzzylinder (30) hat ein Gehäuse (31), in dem ein Kerneinsatz (40) vorgesehen ist, wobei in dem Kerneinsatz (40) für jede Einspritzdüse (32) ein separater Zuführkanal (44) ausgebildet ist, der mit der jeweils zugeordneten Einspritzdüse (32) strömungsverbunden ist.

In an injection cooler (10) for cooling superheated steam conducted in a pipeline (20), having an injection cylinder (30) arranged at least in sections in the pipeline (20) and provided with a plurality of injection nozzles (32), with a control element (50) , which is connectable with a connection (52) to a coolant supply, wherein in the control member (50) a valve arrangement (60) is provided, with which the coolant supply to the injection nozzles (32) in the injection cylinder (30) is controllable, and with coolant supply lines (70), which are provided between the injection cylinder (30) and the control element (50), wherein for each injection nozzle (32) a separate coolant supply line (70) is provided, the invention provides that the injection cylinder (30) associated ends (71) of the coolant supply lines (70) are fastened to a common first flange plate (73) which can be fixed to a receiving surface (36) on the injection cylinder (30) and that the ends (72) of the coolant supply lines (70) associated with the control element (50) are fastened to a common second flange plate (74) which can be fixed to a receiving surface (56) of the control element (50), the coolant supply lines ( 70) and the flange plates (73, 74) form an assembly (B) which is mountable between the injection cooler (30) and the control member (50). The injection cylinder (30) has a housing (31) in which a core insert (40) is provided, wherein in the core insert (40) for each injection nozzle (32), a separate feed channel (44) is formed, with the respectively associated Injection nozzle (32) is fluidly connected.
