前苏制670t/h锅炉增装蒸汽推动系统的探讨

An Exploration of Installing Steam Run System in the 670t/h Boiler Made in Former Soviet Union

对前苏制670t／h锅炉增装蒸汽推动系统，即在原有的底部联箱内加装蒸汽加热分配管方案，并通过强度校核计算，验明方案的可行性，证实在集箱筒体上开孔，可以满足强度要求。

A plan of installing a steam rum system in the 670t/h boiler made in former Soviet Union was proposed. The steam distributing tubes which were used to heating the water were installed in the bottom headers. The strength check calcu-cation verified that the strength requiremenf 'of the header with a hole drilled on its body can be satisfied,so the plan was feasible.
