摘　　要：根据循环流化床锅炉运行工况特点,分析了一次风道阻力特性。结合风机性能曲线、风道阻力特性曲线及风机相似理论,探讨了风机变工况调节原理及方法,进行了节能分析,分析了采用变频调速调节应注意的问题。According to the characteristics of operational conditions of circulating fluidized bed boiler, the resistance property of primary air duet is analyzed. Combining the fan performance curve, the resistance property curve of the air duet and the similar theory of the fan, the principle and method of the fan adjustment under variable conditions are discussed, the energy-saving analysis is conducted, and the problems to which attention should be paid in variable frequency speed regulation are analyzed.
