Title
(DE) BRENNER ZUM BETRIEB EINES WÄRMEERZEUGERS
(EN) BURNER FOR HEAT GENERATOR
(FR) BRULEUR POUR GENERATEUR DE CHALEUR
Abstract
(DE)
Bei einem Brenner zum Betrieb eines Wärmeerzeugers, welcher im wesentlichen aus einem Drallerzeuger (100) für einen Verbrennungsluftstrom (115) und aus Mitteln zur Eindüsung mindestens eines Brennstoffes in den Verbrennungsluftstrom (115) besteht, ist stromab dieses Drallerzeugers (100) eine Mischstrecke (20) angeordnet, welche Mischstrecke (20) innerhalb eines ersten Streckenteils in Strömungsrichtung eine Anzahl Kanäle in einem Übergangsstück (200) zur Überleitung einer im Drallerzeuger (100) gebildeten Strömung in ein stromab dieses Übergangsstück (200) nachgeschaltetes Mischrohr (20) aufweist. Stromab dieses Mischrohres (20) ist ein Brennraum (30) angeordnet. Der Drallerzeuger (100) ist in einen in sich abgeschlossenen und von dem Verbrennungsluftstrom (115) beaufschlagten Einströmungsquerschnitt (10) integriert.
(EN)
The invention relates to a burner for operating a heat generator. Said burner consists essentially of a swirl generator (100) for a combustion air flow (115) and means for injecting at least one fuel into the combustion air flow (115). Downstream of the swirl generator (100) a mixing section (20) is positioned which in a first part, in the direction of flow, presents a number of channels which are embodied in a transition piece (200) and serve to transfer a flow produced in the swirl generator (100) into a mixing tube (20) positioned downstream of the transition piece (200). A combustion chamber (30) is situated downstream of the mixing tube (20). The swirl generator (100) is integrated into a self-contained inflow cross-section (10) which is subjected to the combustion air flow (115).
(FR)
L'invention concerne un brûleur servant au fonctionnement d'un générateur de chaleur. Ledit brûleur est constitué essentiellement d'un générateur de tourbillons (100) pour un flux d'air de combustion (115) et de moyens pour injecter au moins un carburant dans le flux d'air de combustion (115). En aval du générateur de tourbillons (100) est placée une section de mélange (20) qui, dans une première partie, dans le sens du flux, présente un nombre de canaux dans une pièce de transition (200), lesquels servent à transférer un écoulement produit dans le générateur de tourbillons (100) dans un tube de mélange (20) placé en aval de ladite pièce de transition (200). Une chambre de combustion (30) est située en aval du tube de mélange (20). Le générateur de tourbillons (100) est intégré dans une section d'entrée de flux (10) autonome qui est soumise au flux d'air de combustion (115).
