Description

Gliederheizkessel mit unterem Abbrand für Rohbraunkohlenfeuerung. Der Gliederkessel mit unterem Abbrand für Rohbraunkohlenfeuerung nach dem Hauptpatent stellt eine Vereinigung mehrerer zum wirtschaftlichen Verbrennen von Rohbraunkohle nötiger Einrichtungen und Vorgänge dar; es wird auf einem sattelförmigen Treppenrost unter Zuführung von Luft und Absaugung der Dämpfe und Schwelgase durch besondere Kanäle durch Vorwärmung und Trocknung des Brennstoffes eineVerbrennung von minderwertigen Brennstoffen, in der Hauptsache Rohbraunkohle, erreicht. Angestellte Versuche haben ergeben, daß sich die Wirkung dieser Einrichtungen- verbessern läßt, wenn auf die Mündungen der zwischen den Gliedern vom Aschenfall nach den aufsteigenden Zügen hochgeführten Zusatzluftkanäle Glühkörper aufgesetzt werden, welche die Zündung unverbrannter Gase begünstigen. Auch ist es vorteilhaft, den aufsteigenden Flammen in den Heizzügen nochinals Zusatzluft zuzuleiten, weshalb im Anschluß an das obere Ende der Trennrippen zwischen auf- und absteigenden Zügen, also an den Zugumkehrstellen, die Glieder durchsetzende Luftrohre mit Austrittsöffnungen verlegt sind.Sectional boiler with lower combustion for raw lignite combustion. The articulated boiler with lower burnout for raw lignite combustion according to the main patent represents an association of several for the economical burning of raw brown coal necessary facilities and processes; it is placed on a saddle-shaped step grate with the supply of air and extraction of the vapors and smoldering gases by special Channels by preheating and drying the fuel a combustion of inferior Fuels, mainly raw lignite. Have employed attempts show that the effect of these facilities can be improved if on the Mouths of the between the limbs from the ash fall after the ascending trains raised additional air ducts incandescent bodies are put on, which control the ignition favor unburned gases. It is also beneficial to the rising flames to supply additional air in the heating flues, which is why following the upper one End of the separating ribs between ascending and descending trains, that is at the turnaround points, the links penetrating air pipes with outlet openings are relocated.

Ein Gliederkessel nach der Erfindung ist in der Zeichnung im senkrechten Querschritt und Darstellung des Glühkörpers gezeigt.A sectional boiler according to the invention is in the drawing in the vertical Cross-section and representation of the incandescent body shown.

Der Schamotteglühkörper ist an der Mündung zwischen den vom Aschenfall nach dem Verbrennungsraum führenden Zusatzluftkanälen eingelegt. Durch den Zusatz frischer Luft in der Verbrennungszone werden hohe Temperaturen erreicht, der Schamotteglühkörper dadurch zur Weißglut gebracht, und nun entzündet er die noch vorhandenen brennbaren Gase. An der Umkehrstelle der Gase wird ein alle Glieder durchsetzendes Luftrohr b angeordnet, welches zwischen den Gliedern durch Ausströmöffnungen c Luft denVerbrennungsgasen nochmals zuführt. Diese Luftkanäle sind durch Drehrosetten oder ähnliche Einrichtungen regelbar eingerichtet.The fireclay glow body is at the mouth between the ash fall inserted after the combustion chamber leading additional air ducts. By adding fresh air in the combustion zone, high temperatures are reached, the fireclay incandescent body thereby brought to white heat, and now he ignites the combustible ones that are still there Gases. At the reversal point of the gases there is an air tube penetrating all the links b arranged, which between the members through outflow openings c air the combustion gases feeds again. These air ducts are through rotary rosettes or similar devices adjustable set up.
