法国安尔丹-阿尔斯托姆(Heurtey—Ahlstr(?)m)公司正在设计烧城市垃圾的沸腾炉。该沸腾炉适用于20万人口的城市,如垃圾干度为30%,则沸腾炉的直径为1.7米;如干度是15%,则炉子直径相应增加到2.75米,炉子规定连续24小时运行。处理十分干燥的垃圾是很有利的。如垃圾的干度是30%,则燃烧每克干质所产生的烟气量为25米~3,干度为15%,则产生65米~3的烟气量。炉膛中烟气上升速度限制于1.5米/秒,以防止泥沙被带走。
Heurtey-Ahlström (France) is designing a boiling furnace for municipal waste. This boiler is suitable for cities of 200,000 people. If the dryness of the garbage is 30%, the diameter of the boiling furnace is 1.7m. If the dryness is 15%, the diameter of the furnace will be increased to 2.75m. The furnace shall be operated continuously for 24 hours. It is advantageous to handle very dry rubbish. If the dryness of the garbage is 30%, the amount of flue gas generated per gram of dry matter burns is 25 to 3, and the dryness is 15%, resulting in an amount of flue gas of 65 to 3 meters. The rate of rise of flue gas in the furnace is limited to 1.5 m / s to prevent sediment from being taken away.
