摘要：PURPOSE:To obtain a high-temperature furnace having a high energy-saving effect by obtaining a fixed concentration and a fixed flow rate of oxygen-rich gas by using a selective gas permeable film whose temperature is constantly heated by waste heat. CONSTITUTION:Air sucked by a blower 13 is heated to a fixed temperature by a heat exchanger 4, cleaned by a prefilter 5, and then reaches the surface of a module 6. Whereupon, the air passes through the selective gas permeable film of the module 6 by means of a decompression pum 8, where oxygen is concentrated and separated, and the air is directed in the form of an oxygen-rich gas to a pathway 7. Furthermore, the pressure of the air is raised to a necessary one by a pressure-rising blower 9 through the decompression pump 8, mixed with a fuel gas sent through a gas cock 12, and burned by a burner 2. After the combustion, the waste gas is heat-exchanged with air by a heat exchanger 4 through a waste heat pathway 3 and then discharged.
