摘　　要： 从过程基本方程出发，建立了单相螺旋管圈及垂直管圈的动态特性方程，并经过二次建模，得到了能够直接求解的微分方程组，将理论计算结果与试验曲线做了比较，证明了模型的正确性，所得结果对进一步研究直流锅炉螺旋管圈水冷壁动态特性具有一定的参考意义。 Based on process basic equations, the authors have set up a dynamic characteristics model for single phase spiral and vertical tube coils. By way of secondary model building obtained is a group of differential equations, which can be solved directly. The comparison of theoretical results and experimental curves attests to the validity of the above cited model. The results given in this paper may serve as reference data and information during the further study of the dynamic characteristics of once through boiler spiral tube coil water walls.
