电站锅炉构架现场加固的几个问题

Some Items on Site Reinforce of Utility Boiler Frame

本文针对电站锅炉构架的实际情况 ,对其中的一些问题进行具体的说明 ,可供锅炉制造厂和电厂的有关人员参考。在计算方法上不是采用现行《钢结构设计规范》中的极限状态设计法及其较繁的计算公式 ,而是采用锅炉行业过去习惯采用的许用应力设计法及其较简单的计算公式。许用应力对材料的最小屈服点大约有 1

The literature has made a wide explanation to the reinforcement and some problems of the ordinary steel structure.This article makes the more concretely explanation and complementarity to some problems about the practical conditions of the utility boiler frame,and supplies the reference to the relative persons of boiler manufacturer and power station.As for the calculation,the old allowable stress design method and the more simple formula are adopted,not the present limit condition calculation method and its complicated formula stated in the 《Steel Structure Design Code》.The allowable stress value has a safety coefficient about 1.5 times or more to the minimum yield point of the material.
