Description

Die Erfindung betrifft einen Brenner für feste Brennstoffe mit getrennter Primär- und Sekundärverbrennungsluftzuführung, einem Durchbrandrost und einer sich daran anschließenden Zyklonbrennkammer.The invention relates to a burner for solid fuels separate primary and secondary combustion air supply, a burn-through grate and an adjoining one Cyclone combustion chamber.

Bekannte Brenner dieser Art, eingebaut in Festbrennstoffheiz­ kessel können die Brennstoffe nur bedingt wirtschaftlich nutzen und stellen hohe Ansprüche an die Brennstofform.Known burners of this type, installed in solid fuel heating Boilers can only use the fuels economically to a limited extent use and place high demands on the form of fuel.

Ursache für die allgemein schlechte Brennstoffausnutzung sind die für die Verbrennung nicht günstigen Verbrennungsluftzu­ führungen, zu kleine Feuerräume oder ungünstige aerodyna­ mische Gegebenheiten in den Feuerräumen.The cause of the generally poor fuel utilization are the combustion air, which is not favorable for the combustion guides, too small fireboxes or unfavorable aerodyna mixing conditions in the fireboxes.

Aufgabe der vorliegenden Erfindung ist es, einen Brenner für feste Brennstoffe der eingangs definierten Art so auszubilden, daß trotz geringem fertigungstechnischen Aufwand der Heizwert von festen Brennstoffen mit hohem Wirkungsgrad und unter Scho­ nung der Umwelt genutzt werden kann.The object of the present invention is to provide a burner for to train solid fuels of the type defined at the beginning, that in spite of low manufacturing costs, the calorific value of solid fuels with high efficiency and under Scho environment.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß den Brennstoffen über Öffnungen im Primärluftkanal gezielt und an mehreren Stellen die für die Primärverbrennung notwendige Ver­ brennungsluft zugeführt wird. Die entstehenden Brenngase wer­ den durch den Durchbrandrost in die Zyklonbrennkammer geleitet, wo ihnen unmittelbar nach dem Austreten aus dem Durchbrandrost Sekundärverbrennungsluft aus dem Sekundärluftkanal über düsen­ förmige Öffnungen zugemischt wird. In der als Zyklonbrennkam­ mer ausgeführten Brennkammer können die Gase bei langer Ver­ weilzeit und guter Durchmischung vollkommen ausbrennen. Da­ nach verlassen die ausgebrannten und heißen Gase die Brenn­ kammer über eine Auslaßöffnung. Wesentlich ist, daß mit diesem Brenner auch kleinstückige Brennstoffe wie Brikett oder grobes Hackgut genutzt werden kann. This object is achieved in that the Targeted and on fuels through openings in the primary air duct several places the necessary for the primary combustion Ver combustion air is supplied. The resulting fuel gases which is directed through the burn-through grate into the cyclone combustion chamber, where they immediately after exiting the burn-through grate Secondary combustion air from the secondary air duct via nozzles shaped openings is mixed. In which came as a cyclone mer executed combustion chamber, the gases can with long Ver completely burn out because of the time and thorough mixing. There after the burned out and hot gases leave the kiln chamber through an outlet opening. It is essential that with this Burners also use small-sized fuels such as briquette or coarse Wood chips can be used.  

Für Montage und Reparaturzwecke ist es von Bedeutung, daß der Brenner ohne Zuhilfenahme von besonderen Werkzeugen und Binde­ mittel wie Mörtel in den Kessel eingebaut und gegebenenfalls auch ausgewechselt werden kann.For assembly and repair purposes, it is important that the Burners without the use of special tools and bandages medium like mortar built into the boiler and if necessary can also be replaced.
