WASTE MATERIAL MELTING FURNACE

摘要

A waste melting furnace (2) for drying, thermally decomposing, and melting waste comprises a cylindrical main part (20) extending vertically so as to form a space for containing the waste and guide the waste from upside to downside; a melt reservoir part (22), joined to a lower side of the main part along a center axis of the main part (20), for retaining melt generated from the waste; and a gas induction part (21), joined to an upper side of the main part (20) along the center axis of the main part (20), for collecting a gas generated from the waste and guiding the collected gas to an exhaust port (26). The main part (20) has a taper part (24) having an inner cross-sectional area gradually decreasing to the downside. The taper part (24) vertically occupies the largest height in all of parts constituting the main part (20).
