ABSTRACT:
A furnace for burning oil or gas. The furnace has a vertical, cylindrical water jacket, with a combustion chamber being disposed at the upper end of the furnace, and a flue gas collector being disposed at the bottom end of the furnace. At least one ancillary heating tube leads downwardly in the water jacket from the combustion chamber to the flue gas collector. At least the bottom half of the ancillary heating tubes are provided with a corrosion-resistant inner side. Cup-shaped guide elements are disposed one above the other within the heating tubes. The upper rim of each of the guide elements rests against the wall of the heating tube, and the recessed cup portion of each of the guide elements is spaced from the wall of the heating tube. This recessed cup portion has radially oriented holes for directing a plurality of flue gas streams radially against the wall of the heating tube. Below the opening of the heating tube, the flue gas collector is provided with a chamber for collecting condensate. This chamber can be emptied, and has a corrosion-resistant inner side.
