Description
Rohranordnung für Steiirohrkessel. Um in den Trommeln der Steilxolirkessel ein großes Festigkeitsverhältnis zwischen der durch die Rohrlöcher geschwächten und der vollen Trommelwand zu erreichen, muß die Teilung, also die je zweier aufeinanderfolgender Rohrlöcher einer Rohrreihe möglichst groß gehalten werden; anderseits fordert die Ausnutzung der Heizgase eine möglichst enge Anordnung der Rohre, damit eine große bestrahlte Rohrheizfläche über dem Rost untergebracht werden kann und die Rauchgase gut durchgewirbelt und gegen die Kesselheizfläche gepreßt werden.Pipe arrangement for a vertical boiler. To in the drums of the Steilxolirkessel a large strength ratio between that weakened by the pipe holes and to achieve the full drum wall, the division must be that of two consecutive Pipe holes in a row of pipes are kept as large as possible; on the other hand, the Utilization of the heating gases as close as possible to the arrangement of the pipes, so that a large one irradiated tubular heating surface can be accommodated above the grate and the flue gases be whirled through and pressed against the boiler heating surface.
Es ist bekannt, zur Erreichung dieses Zweckes die Rührlöcher jeder folgenden Reihe gegenüber denen der vorhergehenden Reihe um die halbe Teilung, zu versetzen. Das Festigkeitsverhältnis ist hei dieser Anordnung aber noch niedrig, weil man die Teilung wegen der Heizflächenausnutzung nicht groß machen kann.It is known to use the stirring holes each to achieve this end next row compared to those of the previous row by half the division offset. The strength ratio is still low with this arrangement, because the division cannot be made large because of the utilization of the heating surface.
Um trotz dichter Rohranordnung eine ,große Teilung mit hohem Festigkeitsverhältnis zu erhalten, werden entsprechend der vorliegenden. Erfindung die Rohre der jeweils folgenden R ohrreihe nicht um die halbe Rohrteilung, sondern um einen geringeren Bruchteil, 1/3, 1/4 usw., derselben gegenüber der vorhergehenden Rohrreihe versetzt und dies in so vielen aufeinanderfolgenden Reihen wiederholt, bis in der 3., 4. usw. folgenden Rohrreihe die Lage der Rohrlöcher der Ausgangsreihe wieder erreicht ist. Auf der Zeichnung ist beispielsweise die neue Rohranordnung für den Fall ,dargestellt, daß die Rohrlöcher in, der jeweils folgenden Rohrreihe um ein Viertel der Teilung t gegenüber der vorhergehenden versetzt sind und somit die 5. und auch 9. Rohrreihe mit der ersten, wie durch Schraffierung hervorgehoben, ebenso die 2. mit der 6., die 3. mit der 7., die 4. mit der B. Reihe sich decken. Bei dieser Anordnung erhält trotz der dichten Rohrlage das Festig keitsverhältnis zwischen dem geschwächter und vollen Querschnitt der Trommelwand in den Rohrreihen den durch den weiten Abstand der in einer Reihe aufeinanderfolgenden Rohrlöcher ermöglichten hohen Wert. Je höher der Betriebsdruck des Kessels ist, um so wichtiger ist die Erzielung des hohen Festigkeitsverhältnisses und uni so mehr Vorteil bietet die neue Anordnung.In order to achieve a large pitch with a high strength ratio despite the tight tube arrangement to be obtained according to the present. Invention the pipes of each the following row of pipes not by half the pipe division, but by a smaller one Fraction, 1/3, 1/4, etc., the same offset from the previous row of tubes and this is repeated in as many successive rows until the 3rd, 4th etc. following row of pipes reaches the position of the pipe holes of the original row again is. The drawing shows, for example, the new pipe arrangement for the case that the tube holes in the following row of tubes by a quarter of the pitch t are offset from the previous one and thus the 5th and 9th row of tubes with the first, as highlighted by hatching, as well as the second with the 6th, the 3rd with the 7th, the 4th with the B. row. With this arrangement Despite the tight pipe layer, the strength ratio between the weakened and full cross-section of the drum wall in the rows of tubes due to the wide spacing the high value made possible in a series of consecutive pipe holes. The higher the operating pressure of the boiler, the more important it is to achieve the high strength ratio And the new arrangement offers even more advantages.
