垂直管屏式直流锅炉水动力调整方法研究

Research on hydrodynamic adjustment of vertical water wall once-through boiler

分析了目前现场使用的直流锅炉冷态水动力调整方法的弊病 ,提出了一种新的垂直管屏式直流锅炉水动力调整方法———压降系数法 ,给出了数学模型 ,并指出可根据数学模型编制水动力调整程序 。

The paper analyses the disadvantages of hydrodynamic adjustment method used in once through boilers and brings forth a new method,namely differential pressure factor method.On the base of mathematical model of the method,a program can be developed,by which on line adjustment can be realized.
