Thon furnace with device for smoke combustion and ventilation.

Patentirt im Deutschen Reiche vom 21. December 1877 ab.Patented in the German Empire on December 21, 1877.

Meine Erfindung bezieht sich erstens auf eine besondere Construction der Feuerung bei Thonofen zur vollkommenen Verbrennung des Rauches, zweitens auf eine Einrichtung zur beständigen Bewegung der Zimmerluft, wodurch zugleich die Wangen des Feuerkastens kühl gehalten beziehungsweise vor dem Auseinandertreiben durch die Hitze bewahrt bleiben. Drittens endlich betrifft ein Theil meiner Erfindung eine Vorrichtung an dem Rauchabzugsrohr zur Abführung von Luft aus dem Zimmer oder zur beständigen Ventilation desselben. Zur Rauchverbrennung construire ich den Verbrennungsraum und die Züge meines Ofens in der Weise, wie in beiliegender Zeichnung dargestellt ist.My invention relates firstly to a special construction of the furnace at Thonofen for the perfect combustion of the smoke, secondly for a device for constant movement the air in the room, which at the same time keeps the cheeks of the fire box cool be saved from being blown apart by the heat. Thirdly, finally, part of my invention relates to a device on the smoke outlet pipe for the removal of air from the room or for permanent Ventilation of the same. For smoke combustion I construct the combustion chamber and the Draws my furnace as shown in the accompanying drawing.

a, Fig. i, 2 und 3, ist der Verbrennungsraum, dessen Wände mit Chamottesteinen bekleidet, sind, um der hohen Hitze widerstehen zu können. In diesen Verbrennungsraum oder Feuerkasten ist unten ein Rost_ i__y_on_ Jeu erfestem,. Thon. eingelegt ^ der an einem vorderen Ende eine Aufkrempung besitzt, durch welche durch verschiedene Löcher Luft zu dem Brennmaterial zuströmen kann. Der Feuerkasten hat an seinem oberen Theile eine Thür h zum Einfüllen des Brennmaterials. Diese Thür ist so eingerichtet, dafs sie fest verschlossen werden kann. Eine zweite Thür i liegt gerade vor dem Thonroste b. Gegenüber der Aufkrempung dieses Rostes besitzt diese Thür i eine regulirbare Oeffnung mit Stellschraube, durch welche nach Belieben und nach Bedürfnifs Luft eingelassen werden kann. a, Fig. 1, 2 and 3, is the combustion chamber, the walls of which are clad with chamotte stones, in order to be able to withstand the high heat. In this combustion chamber or fire box is a grate_ i__y_on_ Jeu erfestem below. Clay. inserted ^ which has a crimp at a front end through which air can flow to the fuel through various holes. The fire box has, at its upper portion a door h for filling of the fuel material. This door is arranged in such a way that it can be firmly closed. A second door i is just in front of the clay grate b. Opposite the Aufkrempung this grate this door having air can be admitted i regulirbare an opening with set screw, by which to taste and after Bedürfnifs.

Zwischen beiden Thiiren liegt ein eisernes Thürgestell, und durch eine durch einen Schieber verstellbare Oeffnung k kann ebenfalls Luft eingelassen werden.An iron door frame lies between the two doors, and air can also be let in through an opening k which can be adjusted by a slide.

Eine dritte Thür m, zum festen Verschlufs eingerichtet, befindet sich im Thürgestell und mündet unter den Thonrost b. A third door m, set up for permanent closure, is located in the door frame and opens under the clay grate b.

Von der Unterkante der oberen Thür h, bis herab auf die Aufkrempung des Thonrostcs, hängt an der Innenseite des eisernen Thürgestelles ein eiserner Rost r. Um das Feuer in dem Verbrennungsraum in Gang zu bringen, legt man Holz auf den Thonrost, die Kohlen oder Koks darauf und entzündet das Brennmaterial. Hierbei läfst man sowohl die regulirbare Lufteinströmungsöffnung der Thür i, als auch den Schieber k offen und stellt die Klappe e unter dem Roste in die durch punktirte Linien angedeutete Lage; Die Thür m kann bei Ingangsetzung des Feuers ebenfalls geöffnet bleiben.From the lower edge of the upper door h, down to the crimping of the clay grate, hangs an iron grate r on the inside of the iron door frame. To start the fire in the combustion chamber, wood is placed on the clay grate, the coals or coke on top and the fuel is ignited. In doing so, both the adjustable air inlet opening of the door i and the slide k are left open and the flap e is placed under the grate in the position indicated by the dotted lines; The door m can also remain open at start-up of the fire.

Das Feuer wird nun wie bei einem gewöhnlichen Ofen in Brand gerathen, indem die nöthige Luft durch die Oeffnung der Thür i, durch den Schieber k, wie auch durch die untere Thür m einströmen kann. Die Verbrennungsgase gehen dann durch zwei Oeffnungen a' in je einem verticalen Kanal nieder, steigen in den beiden Kanälen β² in die Höhe, gehen dann, die Scheidewand s' überschreitend, in den Kanälen «³ nieder durch die Oeffnungen a³ a³ in den Mittelzug α^Λ, von wo aus sie, dem Wege der Pfeile folgend, im Kanal a* herabfallen und im Kanal a° wieder emporsteigen, um durch die Oeffnungen a¹ in den Kamin zu entweichen.The fire will now catch fire like an ordinary stove, in that the necessary air can flow in through the opening of the door i, through the slide k, as well as through the lower door m . The combustion gases then go down through two openings a 'in a vertical duct each, rise in the two ducts β ² , and then, crossing the partition s ', go down in ducts ³ through the openings a ³ a ³ in the central pull α ^Λ , from where, following the path of the arrows, they fall down in canal a * and rise again in canal a ° in order to escape through openings a ¹ into the chimney.

Bis dahin geschieht die Verbrennung in der gewöhnlichen Weise.Until then, the incineration takes place in the usual way.

Wenn nun aber das Feuer gehörig in Gluth ist, stellt man die Klappe e in die in Fig. 2 angegebene horizontale Lage und schliefst alle Thiiren fest zu. Dagegen - läfst man Luft durch die Regulirschraube der Thüre i eintreten, welche durch die Löcher der Aufkrempung des Thonrostes unmittelbar mit dem .glühenden Brennmaterial auf diesem Roste in Berührung tritt und an dieser Stelle eine lebhafte Verbrennung erzeugt.But when the fire is properly glowing, the flap e is placed in the horizontal position indicated in Fig. 2 and all doors are closed tightly. On the other hand, air is allowed to enter through the regulating screw of door i , which comes into direct contact with the glowing fuel on this grate through the holes in the crimped up of the clay grate and produces a lively combustion at this point.

Durch den Schieber k tritt ebenfalls Luft ein, welche sich durch die Spalten des Rostes r ■ ihren Weg nach dem glühenden Brennmaterial sucht. Die hocherhitzten Verbrennungsgase nehmen nun ihren Weg durch die Züge des Ofens, wie oben beschrieben, treten aber unten nicht unmittelbar aus dem Kanal a⁶ in den Kanel «°, sondern werden durch die horizontal gestellte Klappe e gerade unter den Thonrost gewiesen. Da wegen der hohen Erhitzung der Gase diese zunächst ihren oben beschriebenen Weg nicht ändern, sondern über dem Roste aufwärts strömen, so müssen die nicht vollkommen ver-Air also enters through the slide k and searches its way through the gaps in the grate r to find the glowing fuel. The highly heated combustion gases now make their way through the ducts of the furnace, as described above, but do not exit directly from the duct a ⁶ below into the duct, but are directed through the horizontally positioned flap e straight under the clay grate. Since the gases do not change their path described above because of the high level of heating, but rather flow upwards over the grate, the gases do not have to be completely

Claims

The parts burned again before they flow into the canal tf °, flow towards the strongly heated clay grates. The violent draft flowing up under this grate ripens the greater part of the combustion gases through the grate and through glowing fuel, whereby all parts that are not yet completely burned are completely burned. Here it is absolutely necessary that the door m under the grate be firmly closed, because otherwise, according to my observations, the combustion gases flow down through the grate only directly into the channel a " .

One must imagine this process during combustion as the movement of the Water with a water heater. The high-tension, heated gases flow first upwards and branch out in the various channels, giving their warmth to the Furnace walls and flow into the channel at a lower speed and temperature, who first leads them to the chimney. In this way, just before you enter this channel want to enter, they come into contact with the strongly heated clay grate and flow now, because the lift of the gases is greater here, through this into the glowing fuel, to do the same way again as before. A part of the combustion gases is constantly sucked off directly from the chimney.

Instead of letting the air pass through the cracks in the clay grate, you can also use the Let the clay grate rise vertically on both sides of the fire box so that the Air can brush against the hot grate bars.

The device for the constant movement of the room air, which at the same time affects the cheeks of the fire box consists of the following:

The partition walls, which separate the firebox from the two lateral flues ti ' ¹ a ³ , are made from a single piece of a hollow, fired clay slab w.

To protect against the burning of the plates, they are always used against the fire box clad with a fireproof facing brick layer, which you can use when burned can easily be renewed without having to wear down the furnace.

The hollow clay slabs w with their narrow slits η η are in connection with the space cc . This space is formed by the hollow base plate of the stove and is connected to the hallway through an opening, so that fresh air can be continuously fed into the room. This air rises through the narrow slits η η and warms up. At the same time it cools the hollow plates ww sufficiently so that the heat cannot drive the furnace walls apart.

The heated air enters the furnace niche on both sides through openings // off and mixed here with the vapors of the water contained in a vessel, g. The vessel is not in contact with the plate touched by the fire, so that the water does not come to the boil.

If instead of fresh air from the hallway ago can enter the room, we were sleeping by the rooms then leading opening cc by a slide, however, opens another leading into the room. The air in the room is then kept constantly in circulation through the gaps η ti .

In both cases, whether the air flows in from the hall or from the room itself, a constant, regular flow of air is obtained in that the rising air warms up on the panels ww , flows out through the openings, mixes with water vapor in the niche and now it is spread in the room.

The third improvement relates to a device on the furnace pipe by means of which you can evacuate air from the room into the fireplace without disturbing the draft of the stove. For this purpose, the furnace tube is surrounded by a sheet metal jacket (see FIGS. 6 and 7). the Smoke or the combustion gases pull through the inner tube into the chimney without interfering with the To come into contact earlier in the room than in the fireplace itself. The sheet metal jacket stands with it the room through a series of openings, which one through a ring-shaped one Close the slider or open it as required; can.

This arrangement has the advantage that the air discharged from the room finds its way is not misplaced by the attached call and that the combustion gases flowing into the chimney at the outlet point into the chimney as a whole Around the inner stove pipe ripen the room air with you. The ventilation is thereby livelier.

I want to mention the two tubular openings ζ in the base of the stove, through which air flows in from the room below and flows out into the same at the top. These are intended to ensure that the heat of the furnace tiles in this part of the furnace can be better released into the air than would be the case by mere radiation on the surface.
