我厂1号、2号炉为上海锅炉厂出产的SG220-100型微正压燃油锅炉。投产以来,由于空气预热器的结构设计不合理,锅炉的冷风道和尾部烟道均发生不同程度的振动,风道多处振裂,不得不停炉检修。为消除振动,曾多次对冷风道进行加固,并在送风机进口风道的不同管段加装了消音器,但效果不明显。在华东电力试验研究所的帮助下,于管组间加装了空气预热器的防振隔板,消除了风、烟道的振动和降低了噪音,收到了良好的效果。
I plant No. 1, No. 2 furnace for the Shanghai Boiler Factory produced SG220-100 micro-positive pressure oil-fired boilers. Since put into production, due to the structural design of the air preheater unreasonable, the boiler air duct and the tail flue occurred in varying degrees of vibration, air duct multiple shattering, had shutdown shutdown. In order to eliminate the vibration, the cooling air duct has been reinforced several times, and silencers have been installed in different sections of the inlet air duct of the blower, but the effect is not obvious. With the help of East China Electric Power Research Institute, an air preheater anti-vibration baffle was installed between the pipe groups to eliminate the wind and flue vibration and reduce the noise and received good results.
