摘要： PROBLEM TO BE SOLVED: To provide a fluid phase converter which is compact and efficiently generates superheated steam and can separate components of a different boiling point for evaporation or condensation. SOLUTION: This fluid phase converter comprises an external pipe 11, and an internal pipe 14 which is arranged in the external pipe 11 with a given space therebetween. Either one of the inner or outer side of the internal pipe 14 is permitted to serve as a heat medium passage through which heat medium flows, while the other side is permitted to serve as a fluid passage through which flows fluid after heat exchanging with the heat transfer medium, so as to be subjected to phase change between a gas phase and a liquid phase. A plurality of heat transfer pieces 20, which have been bonded with each other by heat transfer adhesive, are filled into the fluid passage. Among the pieces, those which are in contact with the wall surface of the internal pipe 14 are bonded thereto by the heat transfer adhesive. Further, the fluid passage is provided with a partitioning wall 21 to have the fluid passage therethrough circulating, and provided with an inlet 15 and an outlet 16 with the wall 21 therebetween.

摘要： PROBLEM TO BE SOLVED: To remove molten fly ash fixed in a duct, without stopping an operation by providing a heater for holding an exhaust gas at a specific temperature or above in an exhaust gas duct to a cooling tower for cooling exhaust gas generated from a melting furnace, and providing at least two systems of the ducts and the towers. SOLUTION: A melting furnace 1 for obtaining a slag A by melting and solidifying an incinerating residue generates an exhaust gas B containing a molten fly ash when operated, and introduces the gas B to a cooling tower 7 via an exhaust gas duct 2 for cooling the gas B. In this case, branching valves 6, 6' are provided to branch the duct 2 into two systems at a prescribed position of the duct 2. Furthermore, a heater 5 is provided to hold an exhaust gas temperature around the duct 2 from the furnace 1 to the valve 6 at 800 deg.C or higher to prevent adherence of the ash to the duct 2 of this portion. If adherence of the ash to the tower 7 of the one system occurs, and to remove this, the tower 7 of the other system is set to an operating state, and the one system is repaired.
