摘要

排烟热损失约占锅炉全部热损失的一半以上，回收烟气余热有助于节能减排。针对烟气余热回收中的腐蚀问题，基于导热塑料设计了耐腐蚀的翅片管换热器。结合1000 WM火力发电机组烟气余热回收的运行参数，运用经验证的模型计算了换热器的换热面积和外形体积，简要分析了塑料热导率和凝结水流程对这些设计参数的影响，所得到的结果有望为烟气余热回收的工程应用提供参考。

Abstract

Heat loss due to exhausted flue gas accounts for more than half of boiler's total heat losses. Flue gas heat recovery helps to reduce both fuel consumption and pollution emission

which is of great significance. One of the main problems in flue gas heat recovery that restricts the flue gas outlet temperature is the low temperature acid corrosion to metal heat exchangers. In order to overcome this problem

an anti-corrosion fin-tube heat exchanger based on thermally conductive plastic was designed as a low temperature economized. Using the heat recovery operational condition in a 1000 MW thermal power plant

the parameters of heat transfer area and outline dimensions of the heat exchanger were calculated by a validated mathematical model. Then

the influences of plastic thermal conductivity and number of flow paths on the design parameters were analyzed. It is hoped that the results in this paper could give some reference to engineering applications.
