降低循环流化床锅炉启动时间及用油量的有效措施研究

Study on Effective Measures to Reduce Start-up Time and Oil Consumption of Circulating Fluidized Bed Boiler

循环流化床锅炉的点火启动过程中用油量大,影响电厂的经济效益。本文以西山热电有限责任公司循环流化床锅炉历年来的点火启动过程为参考,对缩短循环流化床锅炉启动时间的问题进行认真剖析,结合运行现场的实际情况,提出优化方案并实施,相较原点火方式,启动时间缩短110~120min,用油量大大节省,提高了经济效益。

Large amount of oil is used in the ignition and start-up of circulating fuidized bed boiler, which affects the economy of power plant. In this paper, taking boiler ignition start-up processin circulating fuidized bed for reference, we analyzed the problem of how to shorten the circulating fuidized bed boiler start-up time, and in combination with the practical situation of the scene of the operation, we put forward the optimization scheme and implement, whose start time is shortened by 110~120 minutes, compared with the original ignition way. And in this way oil is greatly saved, improving the economic beneft.
