RETROFITTING HEAT RECOVERY SURFACE OF BOILER NO.3 AT KAIFENG POWER PLANT[J]. Thermal power generation, 2003, (2): 43-45. DOI: 10.19666/j.rlfd.2003.02.014.
开封火电厂3号炉尾部受热面改造
摘要
介绍了开封火电厂 3号炉尾部受热面改造的情况
分析了锅炉某一部件变化对锅炉整体性能的影响
提出在尾部受热面改造时
必须校核锅炉整体性能
并采取相应的改造措施。改造中采用的蝶形肋片管省煤器
能在有限空间内布置更多的受热面
对降低锅炉排烟温度效果显著
Abstract
The successful retrofitting experiences of heat recovery surface of boiler No.3 at Kaifeng Power Plant have been presented
the influence of changing some parts of a boiler upon the entire performance of it being discussed
hence
the performance of entire boiler must be checked when the heat recovery surface of it is to be retrofitted
and corresponding improved measures should be taken. The butterfly type fined tube economizer which was used in the retrofit enables more heating surface can be arranged into a limited space
and being effective for lowering the exhaust gas temperature of the said boiler.
