摘要
裕东电厂2×315MW机组配套脱硫系统于2007年5月投入运行。脱硫系统投运后,由于增加了脱硫塔设备,引风机后烟道系统阻力发生改变,单台锅炉两台并列运行的轴流式引风机出现了抢风现象,直接影响机组的安全稳定运行。为了解决上述问题,2009年5月,裕东电厂对现有的引风机进行了改造,经过运行观察,收到了预期效果。
Yudong power plant 2×315MW units, auxiliary FGD system was put into operation in May 2007.Alter the desulfuration system put into operation,by increasing the desulphurization tower equipment, after the induced draft fan flue gas system resistance changed.Parallel operation of single Boiler＇s two axial flow fans appeared to grab the wind, which directly affect the safe and stable operation of the units.In order to solve the above problems,Yudong power plant transformed the existing fan in May 2009.After observing operation, we received the expectation effect.
