摘要:

以某2×350MW机组热电联产项目为例,说明玻璃钢烟囱内筒在火电厂湿法烟气脱硫烟囱中应用的适应性,根据该电厂的实际工况,设计了2种不同的铺层并在现场制作了2种铺层的玻璃钢烟囱内筒管段,对管段进行取样并通过第三方检测机构测试其力学性能,对比它们的原材料成本,为火电厂湿法脱硫后烟囱玻璃钢内筒的铺层设计提供参考。

Abstract:

Taking a cogeneration project of 2×350MW coalfired units as an example, the adaptability of FRP chimney liner in WESP flue gas chimneys of coalfired power plants is expounded. According to practical working condition,2 kinds of layers are designed and manufactured on site as FRP chimney liner.The pipe sections are sampled and tested for mechanical properties by a thirdparty testing agency. Comparison of raw material costs provide guidance for the layer design of the inner FRP chimney liner after wet desulfurization in thermal power plants.
