CAD program package for the centrifugal fan of utility boiler has been developed in consideration of its low running efficiency, wearing and ashdeposit.
针对目前许多电站锅炉风机运行效率不高，磨损与积灰严重的情况。

All of these provide exact data for on-line monitoring ashdeposit, fulfilling soot-blowing optimization and designing tail-heating surface and decrease the cost.
这些都为在线监测、实现吹灰优化以及锅炉尾部受热面设计提供了准确数据，降低了成本。
