直径9.5米转子转预热器是目前国产最大的预热器。该预热器于80年年底投入运行。投运初阶段,通后上锅厂同志对该预热器的密封结构作了局部改进和现场调整后,预热器密封性能良好。试验测得,该预热器漏风率为5～6%(按美国ASME标准计算),密封性能达到国际先进水平。本文详细叙述了预热器的试验方法、测试数据及整理结果。基于该预热器先进的密封性能,本文除作为一份重要资料外,也可供电厂进行预热器试验作为参考。
9.5 meters rotor diameter rotor preheater is the largest domestic preheater. The preheater was put into operation by the end of 1980. Put into operation the initial stage, after the gutter comrades on the preheater seal structure made a partial improvement and on-site adjustment, the preheater sealing performance is good. Test measured, the preheater leakage rate of 5 to 6% (according to the United States ASME standard), sealing performance reached the international advanced level. This article describes in detail the preheater test method, test data and finishing results. Based on the advanced sealing performance of the preheater, this article is also available to the power plant for preheater test as a reference, except as an important data.
