电厂钢圆煤斗壁厚计算及分析

Calculation and Analysis of the Wall Thickness of Steel Round Coal Bucket in Electric Power Plant

钢圆煤斗是大型火力发电厂主厂房一个重要的构筑物,但现行的国家及部门规程规范中对钢煤斗壁厚计算无针对性的设计条文,工程设计工具书上对煤斗壁厚的计算亦不完善,只有漏斗没有筒身的计算。文章用工程实例,分析了钢圆煤斗的壁厚计算方法。

The steel round coal bucket is an important structure of the main workshop in large-sized steam-electric power plant, however there are no corresponding design standard clauses for the calculation of the wall thickness of the steel round coal bucket in the national and departmental rules and codes, and the calculation of the wall thickness of the steel round coal bucket introduced in engineering design reference books is not perfect, the calculation is only for the hopper and not for the barrel. This paper analyzes the calculating method for the wall thickness of the steel round coal bucket by using actual engineering example.
