Abstract

L'invention concerne un procédé d'émission de gaz de combustion à partir d'une cheminée avec un brûleur pour brûler un combustible liquide à l'intérieur d'une pièce intérieure. Le procédé comprend les étapes consistant à faire passer le gaz de combustion du brûleur à une sortie de gaz de combustion de la cheminée. La sortie de gaz de combustion est dirigée vers l'intérieur de la pièce intérieure. La sortie de gaz de combustion est positionnée de telle sorte qu'une distance linéaire sélectionnée est établie entre la sortie de gaz de combustion et une position sur un plafond ou sur une paroi de la pièce intérieure. Une entrée d'un système d'échange de chaleur est disposée au niveau de la position sur le plafond ou la paroi de la pièce intérieure. Le gaz de combustion est amené à circuler de la sortie de gaz de combustion à l'entrée du système d'échange de chaleur en passant à travers la pièce intérieure.
