(54) A furnace burning oil, gas and oil biofuel


(57) The invention relates to a furnace burning oil, gas or oil biofuel, which furnace is encased by a mantle (1), a front end (2) and a black end (3) and comprises a combustion chamber (4) and tubes (5a, 5b) installed outside the combustion chamber, through which tubes the combustion gases generated by the flame of a burner are arranged to flow out of the furnace. The invention is characterized in that the burner (6) is of a type which generates in the combustion chamber (4) a fluttering flame, and the combustion chamber (4) ends up in an echo chamber (7) arranged in the back section of the furnace, said echo chamber having a sufficient length for producing a sound when the combustion gases generated by the fluttering flame of the burner (6) impinge on the back end (3) of the furnace, the front wall (9) of said echo chamber (7) being provided with outlets for a first tube set (5a) which ends up in a reversing chamber (10) arranged in front of the front end (2) of the furnace, the back wall (15) of said reversing chamber being provided with outlets for a second tube set (5b) arranged parallelly to the first tube set (5a), said second tube set ending up in a second echo chamber (11) arranged in the back section of the furnace, in which second echo chamber the sound produced by the vibrating combustion gas flow reaches a level capable of loosing and discharging ash and soot from all surfaces of the furnace.
