Stellen die gleiche Temperatur erkennen ! ässt und dass. gleichzeitig ein an Kohlenstoff armer Aschenrückstand entsteht.
Durch eine geeignete Bemessung der Luftmenge regelt man den Entgasungs-, Oxydationsund Reduktionsabschnitt derart, dass, von der Oberfläche aus gerechnet, ständig eine Schicht von bestimmter Stärke besteht, an deren Unterseite möglichst fast aller Kohlenstoff verzehrt ist. In der Oberseite dieser Schicht verbrennen gasförmige Bestandteile und fester Kohlenstoff zu Kohlensäure und Waserdampf, die sich dann in der Unterseite unter Aufzehrung von festem Kohlenstoff zu Kohlenoxyd bzw. Wasserstoff reduzieren.
Im unteren Teile der Haube bildet sich dadurch ein immer weiter anwachsender, poröser Klumpen aus der mehr oder weniger zuaammengeainterten Asche (Schlacke). Wegen des dadurch entstehenden Widerstandes wird der Überdruck des Gebläses bzw. der Unterdruck der Saugvorrichtung zweckmässig allmählich verstärkt. Ist der Schlackenklumpen auf eine gewisse Stärke angewachsen, z. B. 1 M, so hört man mit der Brennstoffzufuhr auf, treibt aber den Wind noch eine gewisse Zeit durch die Beschickung, immer von oben nach unten. Hiedurch vergast man auch den meisten, noch im Aschenrückstande enthaltenen Kohlenstoff.
Darauf wird der Gaserzeuger von der übrigen Leitung abgeschaltet, die Kappe C gehoben, Haube A durch geeignete Vorrichtungen vom Unterbau entfernt und der Sinterklumpen daraus durch Kippen oder dgl. entleert.

betrieben werden.
Zwecks weitgehender Umwandlung von Kohlensäure in Kohlenoxyd kann man die aus dem Roste austretenden Gase nachher noch durch eine glühende Schicht von Koks oder dgl. leiten.
Für manche Brennstoffe ist es wegen der einfacheren Feuerführung empfehlenswert, das Feuer schneller steigen zu lassen und den dadurch im Rückstande verbleibenden, grösseren Koksrest bei dem nach Beendigung der Brennstoffzufuhr anschliessenden Ausbrennen. zu vergasen.
Wenn dagegen wenig Koks im Rückstande nach Beendigung der hauptsächlichen Ver-

Make recognize the same temperature! and that at the same time a low carbon ash residue is formed.
The degassing, oxidation and reduction section is controlled by a suitable measurement of the air volume in such a way that, calculated from the surface, there is always a layer of a certain thickness, on the underside of which almost all carbon is consumed. In the upper side of this layer, gaseous components and solid carbon burn to form carbonic acid and water vapor, which are then reduced in the underside with the consumption of solid carbon to carbon dioxide or hydrogen.
In the lower part of the hood, an ever growing, porous lump forms from the more or less coalesced ash (slag). Because of the resulting resistance, the overpressure of the fan or the underpressure of the suction device is expediently gradually increased. Has the lump of slag grown to a certain thickness, e.g. B. 1 M, then you stop with the fuel supply, but the wind drives through the charging for a certain time, always from top to bottom. This also gasifies most of the carbon still contained in the ash residue.
The gas generator is then switched off from the rest of the line, cap C is lifted, cap A is removed from the substructure using suitable devices and the sinter lump is emptied from it by tilting or the like.

operate.
For the purpose of extensive conversion of carbonic acid into carbonic oxide, the gases emerging from the grate can afterwards be passed through a glowing layer of coke or the like.
For some fuels, it is advisable to let the fire rise more quickly because of the simpler fire control and the larger coke residue that remains in the residue during the subsequent burnout after the fuel supply is stopped. to gas.
If, on the other hand, there is little coke remaining after the main
