 Sammelkammer immer in eine Zone von höherer Temperatur gelangt, so wird hierdurch jede Stockung in der Wärmeaufnahme vermieden und eine günstige Ausnutzung der Heizgase erreicht, also gerade die Mängel vermieden, welche alle, bis jetzt bekannt gewordenen Rauchkammer-   iiberhitzer   besitzen und die infolge der eingangs erwähnten wechselnden Dampfführung die Heizgase nur zum Teil ausnutzen, somit zur Erzielung gleicher   Überhitzungsgrade   wesentlich grössere Heizflächen benötigen als vorliegender Überhitzer. 



   Für solche Kessel, bei denen die Rauchgase nach unten abgeführt werden sollen, wie es bei   ortfesten   Anlagen vorkommen kann, braucht der vorliegende Überhitzer weder in Form noch Lage geändert zu werden ; es ist dann nur nötig, die   Dampfanschlüsse   umzuwechseln und dipAblenkungsbüchse um   180  zu   drehen.

 When the collecting chamber always reaches a zone of higher temperature, this avoids any blockage in the absorption of heat and a favorable utilization of the heating gases is achieved, i.e. precisely the deficiencies which all smoke chamber superheaters known up to now have and which are due to those mentioned above are avoided alternating steam routing only partially utilize the hot gases, so to achieve the same degree of superheating requires significantly larger heating surfaces than the existing superheater.



   For those boilers in which the flue gases are to be discharged downwards, as can happen with stationary systems, the superheater does not need to be changed either in shape or position; it is then only necessary to switch the steam connections and turn the dip deflection sleeve by 180.

Claims

PATENT CLAIM: Superheater built into the smoke chamber of heating tube boilers with superheater tubes running in a serpentine direction in the direction of the boiler axis, characterized in that the superheater tubes (cJ, which connect a distribution chamber (a) and a collecting chamber (b) and consist of several rows of approximately equal lengths under sir'h, are symmetrical are arranged right and left and coaxially in the annular space of the smoke chamber in such a way that the steam flowing through continues to reach zones of higher temperature.
