Abstract

Bei einem Vormischbrenner (18) mit axialer oder radialer Luftzuströmung, bei welchem die Verbrennungsluft (15) aus einem vor bzw. um den Brenner (18) angeordneten Plenum (27) in den Brenner (18) strömt und ihr auf dem Weg durch den Brenner (18) Brennstoff (12, 13) beigemischt wird, ist zwischen dem Plenum (27) und dem Brenner (18) ein perforiertes Bauteil (24) mit einer Wanddicke (s) und Öffnungen (25) mit jeweils einem Durchmesser (d) und einem Abstand (t) zueinander abgeordnet, welches die hindurchströmende Verbrennungsluft (15) in kleine definierte Strahlen aufteilt, die sich nach einer bestimmten Lauflänge (l) wieder vereinigen, wobei das Verhältnis von Wanddicke (s) zum Durchmesser (d) der Öffnungen (25) grösser/gleich eins ist und wobei das Verhältnis zwischen der Durchströmfläche des Bauteiles (24) und der möglichen Einströmfläche in den Brenner (18) in Abhängigkeit von der Brennerart grösser/gleich eins ist.

Figure 00000001
In a premix burner (18) with an axial or radial air inflow, in which the combustion air (15) flows from a plenum (27) arranged in front of or around the burner (18) into the burner (18) and on its way through the burner (18) fuel (12, 13) is mixed between the plenum (27) and the burner (18) is a perforated component (24) with a wall thickness (s) and openings (25) each with a diameter (d) and a distance (t) from each other, which divides the combustion air (15) flowing through into small defined jets which reunite after a certain run length (l), the ratio of wall thickness (s) to diameter (d) of the openings (25 ) is greater than / equal to one and the ratio between the flow area of the component (24) and the possible inflow area into the burner (18) is greater than / equal to one depending on the type of burner.
