Abstract

Die Erfindung betrifft einen Brenner für einen Biomasse-Brennstoffkessel und einen Biomasse-Brennstoffkessel mit einem Brenner.The invention relates to a burner for a biomass fuel boiler and a biomass fuel boiler with a burner.

Es ist Aufgabe der Erfindung, einen verbesserten Brenner für einen Biomasse-Brennstoffkessel bereitzustellen. Dabei soll insbesondere bei einem Biomasse-Brennstoffkessel, der eine Brennstoffzuführung nach dem Abwurfprinzip hat, die Partikelemission aus dem Glutbett soweit wie möglich verhindert werden.It is an object of the invention to provide an improved burner for a biomass fuel boiler. It should be prevented as far as possible, especially in a biomass fuel boiler, which has a fuel supply to the discharge principle, the particle emission from the ember bed.

Gekennzeichnet ist der erfindungsgemäße Brenner dadurch, dass der Brenner eine Brenntellervorrichtung (10) mit mindestens zwei übereinander angeordneten Brennerrosten (20,30) aufweist, wobei ein oberer Brennerrost (20) einen Auffangbereich (25) zum Auffangen von zugeführtem, zu verbrennenden Brennstoffs aufweist und ein unterer Brennerrost (30) einen Glutbereich (31) zum Halten von zerfallendem, glühendem Brennstoff aufweist.

Figure imgaf001
The burner according to the invention is characterized in that the burner has a Brenntellervorrichtung (10) with at least two stacked burner grates (20,30), wherein an upper burner grate (20) has a collecting area (25) for collecting supplied fuel to be burned and a lower burner grate (30) has a glow region (31) for holding decomposing glowing fuel.
