摘要

The multiple fuel type boiler has an insulating outer cover (1). A furnace (2) of large dimensions is inside the cover and there is an outlet (7) in the top for furnace smoke etc. An access door (8) is used to feed and remove fuel residues. A burner (9) is mounted in the door and empties into the combustion chamber (11). This cylindrical chamber is closed at the face opposite to the burner by a cover (13), held by stays. Side holes allow combustion gases to escape.
