火力发电厂烟囱内壁耐腐蚀材料选择研究

Selection of Corrosion-resistant Material for the Inner Wall of the Chimney of Thermal Power Plant

本文研究了电厂烟囱的运行工况、烟气特点,分析了电厂烟囱腐蚀的机理。本文根据不同材料的优缺点进行电厂烟囱内筒材料的选择,本文综合分析了玻璃钢的特点,认为玻璃钢烟囱是火力发电厂烟囱内壁耐腐蚀材料的较佳选择。

This paper studies the operating conditions and flue gas characteristics of the power plant chimney, and analyzes the chimney corrosion mechanism. The chimney tube materials should be chosen based on the advantages and disadvantages of different materials. This paper analyzes the characteristics of FRP and thinks that FRP is the better choice of the corrosion-resistant materials for the inner wall of chimney in thermal power plant.
