【摘要】 本文分两个部分。第一部分作者对配有410型锅炉的N125—135/550/550机组提出了四种暖风器方案,并进行了热力分析。在此基础上,通过各方案的综合技术经济比较,提出了该机组暖风器的最佳系统和参数。本文第二部分作者以正在设计中的N125—135/535/535机组为对象,求得了该机组在未设置暖风器以及设置暖风器时的最佳回热参数。更多还原

【Abstract】 This paper comprises two parts. In the first part, the author presents four air prcheater schemes for unit Type N125—135/550/550 with a Type 410 boiler. Thermoanalysis of this subject has been made. Based on this analysis and the synthetic technical and economical comparison of these schemes、the author proposes the optimal system and its parameters.In the second part, taking the unit Type N125—135/535/535 which has been set on foot as an example, the author obtains the optimal regenerative parameters of the unit both with the air proheater and without the air prcheater.更多还原
