摘要
应用模糊综合评价方法对煤粉的着火状态进行定量评估
提出了着火及时性指数:js=b2/(b1+b2+b3)×100%
其值越大
说明着火情况越好。在某电厂锅炉上的试验表明:运行优化调整前
着火及时性指数为19.7%~68.6%
飞灰含碳量5.5%;运行优化调整后
着火及时性指数大幅度增加
达89.6%~92.2%
飞灰含碳量降至4.5%
表明模糊综合评价能准确地反映煤粉的着火状态
为锅炉燃烧调整提供指导。
Abstract
By using fuzzy comprehensive evaluation method in the fuzzy mathematics
the ignition state of pulverized coal has been quantitatively evaluated
putting forward the index of ignition timeliness js=b2/(b1+b2+b3)×100%
the greater its value may become
the better ignition situation is.Test carried on boiler in one power plant shows that the index of ignition timeliness is 19.7% to 68.0% before adjustment optimization in operation
the carbon content in fly ash being 5.5%%;After adjustment optimiation in operation
the index of ignition timeliness has largely increased
reaching 89.6%-92.2%
the carbon content in fly ash has decreased to 4.5%.Application shows that the fuzzy comprehensive evaluation method can accurately reflect the ignition situation of pulverized coal
providing a guide for combustion adjustment of boilers.
