摘要
该文就焦作爱依斯万方电力有限公司2台420 t/h无烟煤锅炉运用高温烟气回流技术、煤粉浓缩技术、分级燃烧技术,进行了成功的改造,在低负荷稳燃、降低飞灰可燃物、减少炉膛出口两侧烟温偏差、提高锅炉效率等方面均取得较为显著效果。这一事实说明四角切圆燃烧方式对无烟煤有较好的适应性,与双拱W火焰燃烧方式相比并不逊色,四角切圆燃烧技术在我国具有良好的技术竞争实力。
Two 420t/h corner anthracite-fired boilers of Jao Zuo AES Wan Fang Power Company Limited were successfully retrofitted by using high temperature gases recirculating tech-nology, pulverized coal enrichment technology and staged combustion technology. In fact the following conspicuous results were acquested: steady-state combustion under low load, depressed unburned combustibles in fly ash, dwindle the flue gas temperature deviation between two sides of horizontal gas duct, elevated boiler efficiency and so forth. This attested that: the adaptability about anthracite in terms of corner tangential combustion is quite good. Than double arch boiler W-flame, they are by no means inferior. In China the technology of corner tangential combustion possesses is very well and it is enough strength to technology competitive.
