摘　　要：本文采用最小二乘法对CFB锅炉冷态试验数据进行处理,通过构造拟合曲线,揭示了料层阻力特性、确定出精确的临界流化风量;通过对拟合数据进行二次拟合,构造了床压、风室风压和床料厚度的对应关系,实现对运行床料厚度的预测。采用该方法编制的数值处理程序对锅炉实际安全试运起到了良好的指导作用。In this paper, we use least squares to process the data of CFB boiler cold test. By building fitting curve, we explore the characteristics of bed resistance and identify the critical fluidizing air blast; By conbining the fitting data, we build relations between bed air pressure, air chamber pressure and bed thickness, and forcast the bed thickness of running boiler. The computing program made in this method has made great effects in guiding CFB boiler to run safely.
