Description

Durch Aufspritzen einer erstarrenden Masse hergestellte Kesseltrommelschutzwand. Zum Schutze der Kesseltrommeln von Wasserrohrkesseln gegen Strahlungswärme und Berührung durch die heißen Rauchgase dienen Schutzwände aus feuerfester Masse, welche Aussparungen zum Durchtritt der Siederöhren besitzen und zweckmäßig in einem kurzen Abstand von der Kesseltrommel angeordnet werden, so daß zwischen der Schutzwand und der Trommel durch eine Luftschicht die isolierende Wirkung noch erhöht wird.Boiler drum protection wall produced by spraying on a solidifying mass. To protect the boiler drums of water tube boilers against radiant heat and contact The hot flue gases serve as protective walls made of refractory material, which have recesses have to pass through the boiler tubes and expediently at a short distance from the boiler drum are arranged so that between the protective wall and the drum the insulating effect is increased by a layer of air.

Eine solche Schutzwand wird meistens aus Formsteinen hergestellt. Neuerdings ist man auch dazu übergegangen, feuerfeste Masse unmittelbar auf die Trommel aufzuspritzen, was sich gut bewährt hat. Will man diese sogenannte Spritzwand in einem gewissen Abstand von der Trommel venvenden, so wäre es notwendig, zunächst eine feste Unterlage aus Blech oder Formsteinen einzubauen, welche die Schicht der aufzuspritzenden Masse tragen soll.Such a protective wall is usually made of shaped stones. Recently there has also been a move to apply the refractory mass directly to the To spray drum, which has proven itself well. If you want this so-called splash wall at a certain distance from the drum, it would be necessary first to build a solid base made of sheet metal or shaped stones, which the layer of should carry mass to be sprayed.

Zweck vorliegender Erfindung ist es, eine nach dem Spritzverfahren hergestellte und in einem Abstand von der Trommel angeordnete Schutzwand zu verwenden, die ohne die bekannten Blech- oder Formsteinträger ausgeführt wird. Um dies zu erreichen, wird vorgeschlagen, sich einer vorläufigen Unterlage zu bedienen, die nach Aufspritzen und Erhärten der feuerfesten Masse wieder entfernt wird, so daß die Schutzwand nur aus der Schicht der erhärteten Spritzmasse besteht. Als Unterlage kommt ein Stoff in Frage, welcher bei der Inbetriebnahme des Kessels durch die Hitzewirkung verkohlt oder vergast, so daß der Raum für die .Luftschicht zwischen Trommel und Schutzwand wieder freigelegt wird. Bewährt haben sich bisher zwischen die Siederöhren gelegte Holzunterlagen, welche vollständig verbrennen und keinen nennswerten Rückstand lassen. Die Siederöhren ebenfalls mit einer vorläufigen Unterlage aus verkohlbarem oder vergasbarem Stoff zu versehen, wie es bereits geschehen ist, erübrigt sich, da, die Spritzmasse beim Austrocknen und Erhärtet: zusammenschrumpft und aus diesem Grunde von selbst um die Siederöhren herum einen ausreichenden Spielraum für ungehinderte Ausdehnung und Bewegung der Siederöhren frei läßt.The purpose of the present invention is to produce one after the spraying process to use protective wall made and spaced from the drum, which is carried out without the known sheet metal or shaped stone carrier. To achieve this, it is suggested to use a provisional pad after spraying and hardening of the refractory mass is removed again, so that the protective wall only consists of the layer of hardened injection molding compound. A fabric is used as a base in question which one is charred when the boiler is started up due to the effect of the heat or gasified, so that the space for the .Luftschicht between the drum and the protective wall is exposed again. So far, between the boiler tubes laid wooden bases, which burn completely and no residue worth mentioning permit. The boiler tubes also have a temporary base made of charcoal or to provide gasifiable material, as has already been done, is unnecessary, there, the spray compound as it dries out and hardens: shrinks and out of this Basically enough space for unhindered people around the boiler Leaves expansion and movement of the boiler tubes free.

Der Erfindungsgegenstand ist in der Abbildung näher erläutert. Sie stellt einen Querschnitt durch eine Kesseltrommel und die erfindungsgemäß angeordnete und ausgebildete Schutzwand dar.The subject of the invention is explained in more detail in the figure. she represents a cross-section through a boiler drum and that arranged according to the invention and formed protective wall.

Mit a sind die Kesseltrommelwandung, mit d die in sie eingewalzten Siederöhren und mit c die Schutzwand bezeichnet. b ist der Luftmantelraum zwischen der Trommel a und der Schutzwand c, der dadurch frei gehalten wird, daß man die Masse der Schutzwand auf eine feste, vorläufige Unterlage aus verkohlbarem oder vergasbarem Stoff aufspritzt, welche bei Inbetriebnahme des Kessels durch die Hitzewirkung vollständig verbrennt. e bezeichnet den die Siederöhren umgebenden Luftmantel, der bei dem Austrocknen und Erhärten der Aufspritzmasse durch Schrumpfung desselben. von selbst sich bildet.With a are the boiler drum wall, with d those rolled into it Boiler tubes and c denotes the protective wall. b is the air jacket space between the drum a and the protective wall c, which is kept free by the fact that the Mass of the protective wall on a firm, temporary base made of charred or gasifiable substance splashes on, which is caused by the heat effect when the boiler is started up burns completely. e denotes the jacket of air surrounding the boiler tubes, the during the drying and hardening of the injection compound due to its shrinkage. forms by itself.
