Title:
焼却灰間接溶融方法及び装置
Document Type and Number:
Japanese Patent JP3552308
Kind Code:
B2
Abstract:
PURPOSE: To prevent any dust from scattering externally owing to exhaust gas by melting and discharging ash in a slanting ash melting chamber while alternately combusting the ash with a regenerative burner including at opposite ends of a radiation pipe a pumping part having a heat storage material and a fuel supply part having a flame keeping part. CONSTITUTION: A plurality of regenerative burners I are disposed on an upper wall of a slanting ash melting chamber 6 perpendicularly to the longitudinal direction of the slanting ash melting chamber 6, each regenerative burner 1 including a pumping part 13 having a heat storage material 3 and a fuel supply part 4 having a flame keeping part 5 at opposite ends of a radiation pipe 2. First, on the side A combustion air introduced from the pumping part 13 is additionally heated with the heat storage material 3 and is forced to enter the radiation pipe 2. In contrast, a fuel introduced from the fuel supply part 4 is mixed with preheating air in the flame keeping pipe 5 to start combustion and is burned in the combustion pipe 2. Simultaneously, the fuel indirectly heats and melts ash 14 in the ash melting chamber 6. Waste gas preheats the heat storage material 3 on the side B and is exhausted. Such combustion is alternately performed on the sides A and B of each burner 1.
