Die Verbrennungsrückstände kommen aus der Verbrennungskammer 3 in den zylinderförmigen Teil 6. Die Verbrennungsrückstände setzen ihre Rotationsbewegung im zylinderförmigen Teil 6 fort. Infolge der Durchmesserdifferenz zwischen der ersten zylinderförmigen Wandung 12 und der zweiten zylinderförmigen Wandung 10 wird die Bewegungsgeschwindigkeit der Verbrennungsrückstände erhöht.The combustion residues come from the
Während der intensiven Rotation fließen die heißen Verbrennungsrückstände aus dem zylinderförmigen Teil 6 hinaus und kommen über den Konfusor 7 in den Feuerungsraum der wärmetechnischen Anlagen.During the intensive rotation, the hot combustion residues flow out of the
Der Konfusor 7 an der Stirnfläche des zylinderförmigen Teils 6 erhöht den Strömungswiderstand. Wegen der Erhöhung des Strömungswiderstands wird der Druck im zylinderförmigen Teil 6 und in der Brennkammer 3 erhöht. Mit dem Druckaufbau nimmt auch proportional dazu die chemische Reaktionsgeschwindigkeit der Verbrennungsrückstände zu. Dabei wird der Verbrennungswirkungsgrad des Brennstoff-Luft-Gemischs erhöht.The
Der Hohlraum 20 wird durch die zweite zylinderförmige Wandung 10 und die dritte zylinderförmige Wandung 19 gebildet. Ein Kältemittel läuft im Hohlraum 20 über den Eintrittsstutzen 21 und den Austrittsstutzen 18 um. Das Kältemittel läuft auch im Hohlkegel 23 über Ein- und Austrittsstutzen 24 und 25 um. Das Kältemittel und der Wärmeschutzstoff 22 stellen die erforderliche Wärmeführung beim Betrieb der Einrichtung zur Brennstoffverbrennung dar.The
Somit stellt die Ausbildung der Einrichtung mit der Verbrennungskammer 3 mit dem tangential angeordneten Brennstoff-Luft-Eintrittsstutzen 14, dem Hohlkegel 23, dem kegelförmigen Teil 5 und dem zylinderförmigen Teil 6, dem in der Brennkammer 3 angeordneten Innenteil 16 und dem Außenteil 17 und dem Konfusor 7 die Erhöhung des Verbrennungswirkungsgrads des Brennstoff-Luft-Gemischs sicher.Thus, the formation of the device with the
