摘    要:焦作丹河发电有限责任公司2号煤粉炉是410t/h四角喷燃高压煤粉锅炉。1999年5月应用双稳可调浓淡煤粉燃烧技术对中、下层燃烧器进行改造,改造后运行情况良好,低负荷锅炉效率从89.92%提高到91.15%;在40%-50%负荷下不投助燃油能稳定燃烧;煤种适应性较广泛,锅炉运行安全性和经济性都有所提高。

关 键 词:煤粉锅炉  浓淡煤粉  燃烧技术

Abstract:The No.2 Unit (410t/h, 100MW) of Jiaozuo Danhe Power Generation Co. Ltd., was put into use in 1975. To stabilize the combustion without oil at low load, eight original designed burners which had been placed in the middle and bottom level on the No.2 boiler, were replaced with the controllable pulverized coal (PC) rich/lean burners. The practice of operation after the retrofit proves that stable combustion can be achieved at 50% load without support oil, even at 40% load. Boiler efficiency increases to 91.15% from 89.92% at half load (50MW). It is shown that novel burners can make a good performance and combustion can keep stable even when the character parameters of coal change in the large scope. Generally the application is successful and economic benefits will be greatly achieved from now on. Figs 6, tables 4 and refs 8.
Keywords:boiler  pulverized coal  rich/lean burners  combustion
