Based on the theories of combustion aerodynamics and fluid mechanics, and also the experiments, this paper presents an approximate calculation method of arch design for chain-grate stoker by means of the momentun summation principle. This method can be used to determine the size and the direction of the complex momentun and the position of the point K at which the complex momentun intersects the front arch. The calculations and the experiments show that when the point K is situated in the range of 4/5 of the linear part for front arch and the angle between the complex momentun and the linear part of the front arch δ≥110°, the calculated relative height b/L of the front arch is appropriate. For the chain-grate stoker in operation, the ratio of air distri- bution of the air chambers can be optimized by using momentun summation principle based on the fixed geometric sizes and thus to improve the economy and safety of the stoker.

本文在燃烧空气动力学、流体力学的基础上,通过试验研究,提出用动量法则进行火床炉炉拱布置设计的近似计算方法。根据组织炉内空气动力工况的要求,该方法可以确定各拱出口气流动量与上升气流动量的合动量的大小、方向及其与前拱交点K的位置。经理论计算和试验结果综合提出,K点位置在前拱直段的4/5范围内、合动量与前拱直段的交角δ≥110°时,计算所确定的前拱相对高度b/L是适宜的。对已运行的锅炉,可按动量法则在既定的几何尺寸下,确定风室的配风比,使锅炉达到经济、安全的运行。

本文分析了有关火电机组变压运行的一些问题,阐明了当初设计为定压运行的锅炉改为变压运行以后,蒸汽汽温控制点可以延伸到更低负荷。本文通过热力计算揭示了变压运行时蒸汽在高压缸内的理想焓降欠于变压运行时蒸汽在高压缸内的理想焓降;定压运行时高压缸内效率低于变压运行时高压缸内效率。本文还指出变压运行机组,只要调节阀留有适当的节流储备,其负荷响应能力可达到定压运行机组的负荷响应能力水平.
