A first flow passage (R1) in which uncombusted gas (G1) that contains a combustible fuel is injected from a nozzle hole that is smaller than the flame quenching distance at a flow speed to thereby enable flame maintenance is combusted, and thereby enables flow of combustion gas (G2) resulting from such combustion, and a second flow passage (R2) formed about the first flow passage and enabling flow of uncombusted gas supplied through the nozzle hole are provided. According to the present invention, the combustion chamber in a heating apparatus that heats a liquid to be heated is be reduced in size, the flame in the combustion chamber can be stabilized, and energy efficiency can be improved.
L'invention porte sur un appareil de chauffage qui comprend : un premier canal d'écoulement (R1) dans lequel un gaz non brûlé (G1) qui comprend un carburant combustible, éjecté à travers un trou de buse (12) défini pour être plus petit que la distance d'extinction et à un débit qui permet à une flamme d'être maintenue, est brûlé, et à travers lequel s'écoule un gaz de combustion (G2) qui est généré par la combustion ; et un second canal d'écoulement (R2) formé autour du premier canal d'écoulement, dans lequel le gaz non brûlé distribué s'écoule à travers le trou de buse. L'invention permet de diminuer la dimension de la chambre de combustion dans l'appareil de chauffage qui chauffe un fluide devant être chauffé, stabiliser la flamme dans la chambre de combustion et améliorer le rendement en énergie.
