摘要
对一种目前出现的新型自立式双筒钢烟囱进行有限元计算分析,并将其与等高的塔架式钢烟囱进行分析对比。由此得到结论:两类烟囱各有优缺点,就分析模型而言,塔架式烟囱经济性较差,材料利用率较低;新型自立式烟囱可以节省用钢量,但平面刚度分布不均。
This paper analyzes a new self-standing dual-tube chimney system using FE model,which is compared with a tower-type steel chimney from which it is concluded that the former has poor material utilization,the latter is economical but has a uneven distribution of plane stiffness.
