循环流化床锅炉旋风分离器数值模拟及改造
摘要
某台循环流化床锅炉自投运以来
由于旋风分离器效率较低使得飞灰可燃物含量较高
严重影响了锅炉的经济运行。为了提高旋风分离器的分离效率
利用数值模拟技术对分离器的改造方案进行了优化。模拟结果和改造后的实测数据显示
改造后飞灰含碳量由23.83%降至19.65%
锅炉运行经济性提高。
Abstract
From putting one circulating fluidized bed(CFB) boiler into operation
the unburned combustible content in flyash discharged from the said boiler is high due to low efficiency of the cyclonic separator
affecting seriously economic operation of the boiler.In order to enhance the separating efficiency of the said separator
the retrofitting scheme of the said separator has been optimized by using the numerical simulation technology.The result of simulation and measured data after retrofitting show that the unburned combustible content in flyash has been decreased from 23.03% to 10.65%
the economic efficiency of boiler in operation has increased to some extent.
