Abstract

The burner head consists of a mixing chamber (A) with air inlet passages (B). The head has a guide crown (C) and a flame stabilising ring (D). The system ensures correct mixing of the air and gas mixture with a flame spreader with silent operation. The mixture of air and gas is effected without pre-mixing outside the turbulent combustion zone by guiding the flame over the outside of the burner by the ribbing in the guide crown.

Description

Ttte de combustion pour brbler à gaz à air soufflé.Combustion head for blowing with blown air gas.

Ce dispositif assure la diffusion du mélange air/gaz, la stabilisation de la flamine, un accroissement du front de flamme, un fonctionnement silencieux. flans les dispositifs connus de ce genre, le mélange air/gaz est effectué sans prémélange turbulent hors de la zone de combustion, sans stabilisation de la flamme par tuyères de pilotage, sans retenti on turbulente au niveau du front de flamme, sans stabilisation par pilotage des tuyères au niveau des orifices de sortie.This device ensures the diffusion of the air / gas mixture, the stabilization of the flamine, an increase in the flame front, silent operation. In known devices of this kind, the air / gas mixture is carried out without turbulent premix outside the combustion zone, without stabilization of the flame by pilot nozzles, without turbulent sounding on the flame front, without stabilization by piloting nozzles at the outlet ports.

Cette invention permet d'éviter les inconvénients ci-dessus, de réduire considérablement le niveau sonore de fonctionnement.This invention makes it possible to avoid the above drawbacks, to considerably reduce the operating noise level.

Les dispositifs objets de cette invention sont: un élément de mélange turbulent, une couronne de pilotage, une couronne extérieure stabilisatrice.The devices which are the subject of this invention are: a turbulent mixing element, a pilot ring, an external stabilizing ring.

Cette invention peut titre utilisée sur tous les bradeurs à gaz à air soufflé nécessitant un mélange un mélange parfait sans excès d'air, une flamme stable et peu bruyante. This invention can title used on all the blowers with gas blown air requiring a mixture a perfect mixture without excess of air, a stable flame and little noisy.
