Abstract

La présente invention concerne une chaudière à bois de chauffage comprenant une structure transversale à deux passes dans laquelle une chambre de combustion de bois de chauffage inférieure et un échangeur de chaleur supérieur sont associés par une relation verticale. Dans l'échangeur de chaleur, le rendement thermique est amélioré grâce à des ailettes d'échange de chaleur formées soit sur sa surface circonférentielle intérieure, soit sur sa surface circonférentielle extérieure, et à une plaque en zigzag formée à l'intérieur de celui-ci. De plus, l'échangeur de chaleur est conçu de façon à être incliné vers le bas vers un orifice de sortie de fluide situé dans une cheminée d'échappement de fumée. Un ventilateur de tirage est situé dans la cheminée d'échappement de fumée de façon que les gaz de combustion s'échappant de l'échangeur de chaleur sortent sans entrave. Simultanément, le rendement thermique de la chaudière à bois de chauffage peut être amélioré en ajustant la capacité d'échappement de gaz ou la capacité d'aspiration de gaz en ajustant la capacité de soufflage du ventilateur de tirage ou l'ouverture d'un registre de régulation d'air en fonction de la température de l'eau.
