Description
Schrägrostfeuerung. Auf Schrägrosten konnte bisher nicht verhindert «-erlen, claß die Kohlenschicht an den Seiten des Rostes durch Wärmestrahlung der senkrechten Feuerungswände schneller abbrennt als in der mittleren Zone der Kohlen-(lecke. Dies hat den dauernden Nachteil, daß nach der Mitte des Rostes zti die noch dicke Kohlenschicht katun Flainnienbildung zuläßt, während an den Seiten des Rostes die Kohle bereits so lebhaft abbrennt, daß die im Verhältnis zur Mitte zu dünne Kohlenschicht kalte (sogenannte falsche) Luft zum Durchbruch kommen läßt. Die Folge davon ist ein Sinken der Temperatur im Feuerauni und ein unregelmäßiges Nachrutschen der Kohle auf dein Rost.Inclined grate firing. So far it has not been possible to prevent oblique larges «-Erlen, the carbon layer on the sides of the grate by thermal radiation of the burns down faster in vertical furnace walls than in the middle zone of the coal (leak. This has the permanent disadvantage that after the middle of the grate the grate is still thick Coal layer katun allows flainnia formation, while on the sides of the grate the Coal is already burning so vigorously that the coal layer is too thin in relation to the center allows cold (so-called false) air to break through. The consequence of this is a drop in temperature in the Feuerauni and an irregular slipping of the coal on your grate.
Aufgabe der Erfindung ist es, diesem Nachteil ohne Benutzung irgendeines mechanischen Betriebsmittels dadurch abzuhelfen, daß die Ausstrahlung der Feuerungswände zur Förderung des Brennprozesses auf der Mitte der Kohlendecke nutzbar gemacht wird. Dies geschieht gemäß der Erfindung dadurch, daß die den Rost begrenzenden Seitenwände einen nach innen gerichteten Vorsprung und eine ollen daran sich anschließende 1Iohlkelile bilden.The object of the invention is to overcome this disadvantage without using any to remedy mechanical equipment by reducing the appearance of the furnace walls to promote the burning process in the middle of the coal roof is made usable. This is done according to the invention in that the side walls delimiting the grate an inwardly directed protrusion and an adjoining 1Iohlkelile form.
Ein Ausführungsbeispiel des Erfin dnnrsgegenstandes zeigt die "Zeichnung im 1.ängsschnitt und in einem Ouerschnitt nach Linie - 1-B.An embodiment of the invention thin objects shows the "drawing in the 1st longitudinal section and in a cross section along line - 1-B.
An den den Schrägrost a begrenzenden Seitenwänden b wird parallel zum Rost ein aus hochfeuerfester Nasse bestehender Vorsprung c gebildet, der im Schnitt etwa die Form einer Bildrahmenleiste hat. Dieser über dem Rost sich erstreckende Vorsprung nitil3 sich in einer solchen Lage zum Rost befinden, claß seine untere, der Kohlenschicht zugekehrte Fläche durch ihre -Nähe zu dieser dämpfend auf den Brennprozeß wirkt, während die an den Vorsprung sich nach oben anschließende Hohlkehle d die Wärmestrahlen auf die Mitte der Kohlenschicht zurückwirft.The side walls b delimiting the inclined grate a are parallel to the grate, a projection c consisting of highly refractory wet is formed, which is in the Cut roughly in the shape of a picture frame strip. This one extending over the grate Projection nitil3 are in such a position to the grate that its lower, the surface facing the coal layer due to its proximity to this attenuating on the Burning process takes effect while the groove adjoining the projection upwards d reflects the heat rays back to the center of the carbon layer.
Durch entsprechende Abmessung des Vorsprunges kann ein gleichmäßiges Abbrennen der Kohlenschicht auf der ganzen Breite des Rostes bewirkt werden.By appropriately dimensioning the projection, a uniform Burning of the layer of coal can be effected over the entire width of the grate.
