摘要
该文对以前建立的膨胀中心计算模型做了改进 ,并以NG 410 /9.8 M型锅炉为例 ,讨论了其膨胀中心的设置以及导向载荷的计算方法及计算过程 ,重点论述了最小导向载荷、风载荷、地震载荷以及炉膛内压引起的不平衡载荷的计算。采用了竖直向下的计算模型。图 3表 4参
The paper reports on an improvement of the elaborated model, for calculating expansion centers and taking the NG 410/9.8 M type boiler as an example, discusses the import of the expansion center and how, as well as by what procedure, the leading loads are to be calculated. Particularly discussed are the minimal leading load, wind loads, seismic loads, and unbalanced forces caused by the furnaces' Internal pressure. A perpendicular downward calculation model is used.
