Abstract

Abhitzekessel, der innerhalb eines zylindrischen Mantels ( 2 ) eine Vielzahl von Wärmeübertragungsrohren ( 3 ) und ein zentrisch angeordnetes Bypassrohr ( 4 ) umfasst, die jeweils ein Einlassende ( 5 ) und ein Auslassende ( 6 ) aufweisen;
der eine Einrichtung ( 7 ) umfasst, die mit dem Mantel ( 2 ) befestigt ist, zum Einleiten von Wasser ( 31 ) auf der Mantelseite der Rohre ( 3, 4 ),
der eine Einrichtung ( 8 ) zum Einleiten eines heißen Abgasstromes (27) in das Einlassende ( 5 ) der Rohre ( 3, 4 ) und Hindurchleiten des Abgasstromes ( 27) durch die Rohre ( 3, 4 ) in indirektem Wärmeaustausch mit dem Wasser ( 31 ) auf der Mantelseite der Rohre umfasst, um Dampf zu erzeugen und um den eingeleiteten Abgasstrom ( 27 ) zu kühlen,
der eine Einrichtung ( 9 ) zum Ableiten von erzeugtem Wasser/Dampf ( 31 ) und eine Einrichtung ( 10 ) zum Ableiten des gekühlten Abgasstromes ( 27 ) umfasst,
der eine Regeleinrichtung ( 11 ) umfasst, um die Abhitzekessel-Gasaustrittstemperatur in einem bestimmten Temperaturbereich zu halten, wobei durch einen am Auslassende ( 6 ) des Bypassrohres ( 4 ) angeordneten und mittels der Regeleinrichtung ( 11 ) axial verstellbaren Stopfens ( 12 ) die Gasdurchtrittsgeschwindigkeit und -menge im Bypassrohr ( 4 ) regelbar ist,
wobei der Stopfen ( 12 ) durch ein Kühlmedium ( 32 ) kühlbar ist und in das in Strömungsrichtung des Abgasstromes ( 27 ) gesehen konusförmig erweiterte Auslassende ( 6 ) des Bypassrohres ( 4 ) hineinragt und der Gasdurchtrittsquerschnitt ( 22 ) sich innerhalb des von der Innenkontur (19) des Auslassendes ( 6 ) und der Außenkontur ( 20 ) des Stopfens ( 12 ) gegenseitig überloppten Gasdurchtrittsbereiches ( 21 ) und unabhängig von der Lage des geöffneten Stopfens ( 12 ) in Strömungsrichtung des Abgasstromes ( 27 ) gesehen gleichförmig oder ungleichförmig erweitert (Fig. 2).

Figure imgaf001
A waste heat boiler comprising within a cylindrical shell (2) a plurality of heat transfer tubes (3) and a centrically arranged bypass tube (4) each having an inlet end (5) and an outlet end (6);
comprising means (7) fixed to the shell (2) for introducing water (31) on the shell side of the tubes (3, 4),
means (8) for introducing a hot exhaust gas flow (27) into the inlet end (5) of the tubes (3, 4) and passing the exhaust gas flow (27) through the tubes (3, 4) in indirect heat exchange with the water (31 ) on the shell side of the tubes to generate steam and to cool the introduced exhaust stream (27),
comprising means (9) for draining generated water / steam (31) and means (10) for draining the cooled exhaust gas flow (27),
comprising a control device (11) to maintain the waste heat boiler gas outlet temperature in a certain temperature range, wherein the gas passage speed and. By arranged at the outlet end (6) of the bypass tube (4) and by means of the control device (11) axially adjustable stopper (12) amount in the bypass tube (4) is adjustable,
wherein the plug (12) by a cooling medium (32) is cooled and in the flow direction of the exhaust gas stream (27) seen conically expanded outlet end (6) of the bypass tube (4) protrudes and the gas passage cross section (22) within the of the inner contour ( 19) of the outlet end (6) and the outer contour (20) of the plug (12) mutually overblown gas passage region (21) and regardless of the position of the open plug (12) in the flow direction of the exhaust gas stream (27) seen uniformly or non-uniformly extended (Fig. 2).
