摘要： PROBLEM TO BE SOLVED: To prevent damage to a body of furnace by discharging molten ashes together with molten glass out of a molten ash and glass outlet port. SOLUTION: Glass is supplied into a furnace 10 from a glass feed part 2. The glass is melted by means of a burners 4 and stored on the bottom of the furnace so that a molten glass furnace floor 5 is formed. If ashes are introduced from an ash feed part under such conditions, the ashes fall down on the floor 5 and heated by molter glass and the burners 4 and melted. Since the floor 5 is formed from glass having low erosiveness and ashes are fed on the floor to melt the ashes on the molten glass, the molten ashes are prevented from coming in contact with the body of the furnace. The molten ashes are discharged from a molten ash and glass outlet port by causing the ashes to overflow or the ashes are wound up by means of a molten ash and glass winding device with a molten ash and glass outlet port and delivered. The discharged ashes and glass are cooled with water and formed into slag.

摘要： PURPOSE: To obtain a compact, high-efficiency ash melting device where the load per volume can be increased because of its high heat transfer effect. CONSTITUTION: Primary ash is burnt by a primary ash melting burner 4 together with combustion aids such as fuel, air, etc., to turn the ash into molten particles, and the molten particles are sprayed into secondary ash 10 at a high speed together with flame so that heat reaches deep inside the secondary ash 10, stimulating the secondary ash to melt. The primary ash is sprayed into the secondary ash 10 as molten particles at a high speed from the primary melting burner 4 together with flame. As the molten particles that are sprayed at a high speed together with flame have an excellent straight traveling property and effectively hit the surface of the secondary ash layer with the heat and kinetic energy held in the molten particles and the combustion gas, heat is transferred deep inside the secondary ash layer, stimulating the secondary ash 10 to melt.

摘要： PURPOSE: To obtain an indirect heating method and device which is high in economy, and has a short heating-up time and a uniform temperature distribution in a furnace at the time of finish by a method wherein heating is required in the combustion mode using burners when a high-load, rapid heating is required and an indirect heating is carried out in the electric resistance mode after the burners are stopped when a delicate temperature control is required. CONSTITUTION: When a high-load, rapid heating is required, a workpiece 8 is heated by a combustion mode. That is, when fuel and air are supplied to burners 4, combustion starts, flames 9 are formed at heating elements 3 of ceramic radiant tubes and the workpiece 8 is indirectly heated. The exhaust gas is discharged outside through exhaust pipes 5. Next, when delicate temperature control is required, the operation of the burners 4 are stopped and the operation mode is switched to an electric resistance mode. That is, when electrodes 7 are energized, the heating elements 3 serve as heaters and heat the workpiece 8 indirectly. Thus, the combustion mode and the electric resistance mode are selectively switched to each other to perform a best temperature control of the workpiece 8 and obtain quality products.

摘要： PURPOSE:To clean thermal storage bodies while operation is being carried out by setting in a thermal storage chamber a pallet having a multiply- perforated bottom, packing the pallet with thermal storage bodies and connecting the pallet with a vibrator. CONSTITUTION:Combustion is alternately effected in two burner thermal storage chambers 2. When the combustion is effected in one chamber 2, exhaust gas is discharged through another chamber 2 so that sensible heat is recovered by thermal storage bodies 4. When the thermal storage bodies are to be cleaned, vibration is given by a vibrator 5 while the heat recovery is being carried out. Then, the thermal storage bodies 4 are rotated so that dust packed between and adhering to the thermal storage bodies is removed and made to fall down. The fallen dust is discharged through a dust-discharging part 12 composed of a dust scatter prevention plate 10 and a damper 11. Because the pallet 3 is disposed with the bottom thereof positioned in an inclined state, the dust is given the tendency to fall toward filter 7 side so that the dust is collected in the bottom of the dust-discharging part 12. The exhaust gas is discharged by closing an air supply hole 9 and opening an exhaust hole 8.

摘要： PURPOSE:To enhance a melt processing capacity per hour by providing a jet direction varying burner on an upper portion of a rotating furnace casing to face an inner furnace wall, providing a melt discharge and exhaust port in a lower portion of the rotating furnace casing and providing a melt puddling area around the port. CONSTITUTION:A combustion gas, air and ash begin to undergo combustion by a jet direction varying burner 3 provided on a rotating furnace casing 1 while mixing with one another, so that ash in a semi-molten condition is jetted toward a red-hot inner furnace wall 2 from the burner 3 to impinge against the inner furnace wall 2. Owing to such impingement, combustion and melting progress, and ash adhered to the inner furnace wall 2 by impingement is caused by radiation heating to completely melt while rotating together with revolution of the furnace casing 1. Melt 15 along with the combustion gas flows toward a discharge member 7 from a melt discharge and exhaust port 4 through a melt puddling area 5. Accordingly, it is possible to effectively utilize the inner furnace wall 2 which contributes to melting, and thus a melt processing capacity per hour is enhanced.
