Abstract

Un système de chauffage à modulation comprend un échangeur de chaleur à tube possédant une série de brûleurs, un ventilateur dair de combustion doté dun conduit de sortie relié aux brûleurs, le ventilateur dair de combustion peut fonctionner à une première vitesse et à une deuxième vitesse, un premier clapet relie une source de carburant à un premier sous-ensemble de brûleurs, et un deuxième clapet relie une source de carburant à un deuxième sous-ensemble de brûleurs dans lequel le premier et le deuxième clapets ont chacun un taux dallumage faible et un taux dallumage élevé. Léchangeur de chaleur fonctionne à diverses phases de chaleur selon un mélange stable air-carburant.
