本文提出了建立具有分布参数性质的沸腾炉空气埋管的数学模型的一种有效方法， 即积分加权平均、低阶集中参数法（简称积分平均法），并把这种算法与利用高阶（４９ 阶）集中参数模型所得的结果作了对比，两者重合良好．在此基础上，给出了空气埋管。 动态特性的实际算例．并由此得到了两个在控制系统设计中有价值的结论。 In this paper, an effective method to establish the mathematical model of the buried tube in the boiling furnace with distributed parameters is proposed, which is the integral weighted average and the low-order concentration parameter method (referred to as the integral averaging method) Order) centralized parameter model the results obtained are compared, the two coincide well. On this basis, the air buried pipe is given. Actual examples of dynamic characteristics. And thus obtained two valuable conclusions in the control system design.
