摘要
为深入分析燃煤锅炉尾部受热面低温腐蚀的机理,找到尾部余热深度利用的可行之法,本文从低温腐蚀原理、硫酸露点及其凝结形成机理出发,根据我国实际情况,分析比较了国内外使用的预防低温腐蚀、降低排烟温度、高效回收排烟余热的技术、设备及方法的优缺点,结合有效腐蚀理论,指出锅炉尾部烟气余热深度利用的研究方向。
In order to analyze low temperature corrosion mechanism of the coal-fired boiler water tube surface, search for feasible method of depth-utilization of the exhausted flue gas heat energy, low temperature corrosion mechanism, effects of sulfuric acid dew point and condensation on the corrosion formation were discussed. According to the actual situation in power plants, the advantages and disadvantages of waste heat recovery equipments are compared and evaluated based on the effective corrosion theory. The methodology to solve the low temperature corrosion and high effective heat recovery from flue gas is oriented.
