Abstract

Le procédé et le dispositif décrits permettent d'améliorer le comportement au démarrage d'un brûleur à diffusion d'huile (1) pourvu d'au moins un ajutage atomiseur (2) qui atomise finement l'huile dans une chambre de combustion. Immédiatement avant et pendant le début de l'amenée d'huile, un gaz de combustion est amené et allumé à travers au moins un orifice (3) à proximité de l'ajutage atomiseur (2), de façon à générer une flamme d'appui pendant la phase de démarrage du brûleur à diffusion (1). L'invention est particulièrement utile pour atomiseurs d'huile sous pression à aubes directrices, notamment pour ceux qui sont réglés en retour. On peut notamment utiliser pour amener le gaz de combustion un système d'amenée d'eau qui sert à réduire les émissions d'azote pendant la phase de démarrage. Le comportement au démarrage du brûleur à diffusion d'huile devient ainsi presque comparable à celui d'un brûleur à gaz.
