摘要
分析了平方转矩类负载利用变频器调速的节能原理,介绍了循环流化床锅炉风机水泵变频调速改造的方法,通过实例对风机水泵由变阀调节改造为变频调节的节能效果和可靠性进行了对比分析.
The principle of energy saving in squared torque load through frequency converter is introduced.The method of the innovation with frequency converter in circulating fluidized Bed Boiler is discussed.The actual example in the innovation of fan from valve adjust to frequency adjust is given.The reliabilities of the two methods are compared and analyzed.
