Abstract

In a steam generator, a pipe grid, which is designed in such a manner that the rows of pipes lying one behind another can be cleaned by knocking, is mounted at the transition from one smoke gas flue to another. <IMAGE>

Description

Die Erfindung betrifft ein durch Klopfen zu reinigendes, aus mehreren Rohrreihen bestehendes Rohrgitter nach dem Oberbegriff des Anspruches 1 in einem Kessel, das von außen von einem heißen Medium umströmt wird, welches durch die Rohre seine Wärme an ein in den Rohren strömendes Medium abgibt. Dabei wird das außen um die Gitterrohre herumströmende Medium vom Eintritt in das Rohrgitter bis zum Austritt aus dem Rohrgitter abgekühlt.The invention relates to a knock-cleanable Pipe grid consisting of several rows of pipes according to the The preamble of claim 1 in a boiler by a hot medium flows around the outside, which the pipes transfer its heat to one flowing in the pipes Releases medium. This is the outside around the trellis medium flowing around from the entry into the pipe grid up to cooled to exit from the pipe grid.

Dieses Rohrgitter ist angeordnet am Übergang von einem Rauchgaszug zu einem anderen.This pipe grid is arranged at the transition from one Flue gas flue to another.

Es ist bekannt, daß an Rauchgasumlenkungen von einem Kessel­ zug zu einem anderen Rohrgitter angeordnet werden.It is known that flue gas deflections from a boiler train to another pipe grid.

Rohrgitter haben den Nachteil, daß sie nur durch Rußblasen gereinigt werden können.Pipe grids have the disadvantage that they only blow through soot can be cleaned.

Der Erfindung liegt die Aufgabe zugrunde, zwischen zwei Rauchgaszügen ein Rohrgitter zur Abkühlung der Rauchgase zu schaffen, welches durch Klopfen gereinigt werden kann.The invention has for its object between two Flue gas flues a pipe grid for cooling the flue gases to create, which can be cleaned by tapping.

Diese Aufgabe wird gemäß der Erfindung durch die kenn­ zeichnenden Merkmale des Anspruches 1 gelöst.This object is according to the invention by the kenn Drawing features of claim 1 solved.

Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, daß nun zur Rauchgasabkühlung zwischen zwei Rauch­ gaszügen eine Heizfläche vorgesehen werden kann, deren Verschmutzung man nicht mehr befürchten muß, da sie durch eine, als sehr wirkungsvoll bekannte, Klopfvorrichtung gereinigt werden kann. The advantage achieved with the invention is in particular in that now for cooling the flue gas between two fumes gas trains a heating surface can be provided, the Pollution you no longer have to worry about as it gets through a tapping device known to be very effective can be cleaned.  

An den Fig. 1 bis 3 wird das Rohrgitter näher beschrie­ ben. Das Rohrgitter (1) besteht aus mehreren im Rauchgas­ strom hintereinander angeordneten Rohrreihen (2), deren Wärmetauscherrohre (3) zu der vorangegangenen Rohrreihe fluchtend oder versetzt angeordnet sein können. Eine Rohr­ reihe besteht aus mehreren quer zum Rauchgasstrom ange­ ordneten Wärmetauscherrohren (3).The tube grid is beschrie ben closer to FIGS. 1 to 3. The pipe grid ( 1 ) consists of several rows of pipes ( 2 ) arranged one behind the other in the flue gas stream, the heat exchanger pipes ( 3 ) of which can be arranged in alignment or offset with respect to the previous row of pipes. A row of pipes consists of several heat exchanger pipes ( 3 ) arranged transversely to the flue gas flow.

Jede Rohrreihe hat ein eigenes, quer zur Rauchgasrichtung angeordnetes Verteilerrohr (4), an dem die Wärmetauscher­ rohre (3) der einzelnen Rohrreihen (2) angeschlossen sind, daß sie über dieses Verteilerrohr (4) vom in den Rohren strömenden Medium durchflossen werden.Each row of pipes has its own distributor pipe ( 4 ), arranged transversely to the direction of the flue gas, to which the heat exchanger pipes ( 3 ) of the individual rows of pipes ( 2 ) are connected so that the medium flowing in the pipes flows through them via this distributor pipe ( 4 ).

Die Zuführungsrohre (5) zu den in Strömungsrichtung der Rauchgase hintereinander angeordneten Verteilern (4) der einzelnen Rohrreihen (2) werden aus den Rohren der eine Trennwand der beiden Gaszüge bildenden Rohrwand (6) ge­ bildet, und zwar in der Weise, daß die Trennwandrohre (6) in regelmäßiger oder unregelmäßiger Reihenfolge an die Querverteiler (4) angeschlossen sind.The feed pipes ( 5 ) to the one behind the other in the flow direction of the flue gas distributors ( 4 ) of the individual rows of pipes ( 2 ) ge from the pipes forming a partition of the two gas flues forming pipe wall ( 6 ) ge, in such a way that the partition pipes ( 6 ) are connected to the transverse distributors ( 4 ) in regular or irregular order.

Die Rohrsammler (7) der einzelnen Rohrreihen (2) liegen mit ihrer Längsachse in Richtung des Rauchgasstromes, d. h., daß an diese Sammler von den hintereinander liegenden Rohr­ reihen (2) jeweils ein Rohr (3) je Rohrreihe (2) ange­ schlossen ist.The pipe collector (7) of the individual rows of tubes (2) lie with their longitudinal axis in the direction of the flue gas stream, that is, rows of these collectors of the successive tube (2) in each case a tube (3) for each (2), row of tubes is closed.

Durch diese Rohranordnung ist es möglich, daß die einzel­ nen Rohrreihen (2) des Rohrgitters (1) durch eine Klopf­ einrichtung (8) rauchgasseitig gereinigt werden können.This pipe arrangement makes it possible for the individual rows of pipes ( 2 ) of the pipe grid ( 1 ) to be cleaned on the flue gas side by means of a tapping device ( 8 ).

Es schlagen die Klopfhämmer (9) auf die Aufschlagstelle (10) der Verteilerrohre (4).The knocking hammers ( 9 ) hit the impact point ( 10 ) of the distributor pipes ( 4 ).
