Hyflon® PFA’s proven record in heat exchanger applications made it an excellent choice for our latest system de- sign, and its success at Guodian Beilun proves we made a wise choice.” 苏威（Solvay）是特殊高分子材料全球 领先的供应商，今天宣布：其先进 的Hyflon® 全氟烷氧基(PFA)含氟聚 合物 (® Hyflon 是苏威的注册商标) 授权给中国北京的Xinshiyi 能源节 约和环境保护公司开发更为有效和 可靠的600兆瓦烟气余热回收热交 换器，用于大型燃煤发电厂。 北京Xinshiyi的商务总监 Zhang Fang指出： “烟气余热回收热交换器使 用从燃煤锅炉排放出的烟道气能源，可 以减少排放，并有利于满足第十三个五 年计划规定的严格的环境方针。为了支 持中国的计划，我们寻求产业领先的物 料供应商比如苏威，帮助我们开发最前 沿的热交换器，要求热交换器具有更为 出色的性能和可靠性。Hyflon® PFA在 热交换器应用方面的久经考验的记录使 其成为了我们最新设计的系统绝佳的选 择，并且，在国电北仑的成功应用证明 了我们做出的选择是明智的。” 半结晶态全氟化融体状可加工的含 氟聚合物Hyflon® PFA 通过挤出成型成 为热交换器管，然后组装到模块，组成 了北京Xinshiy的系统。这一应用表明苏 威的Hyflon® PFA在中国的首次应用在 大规模600兆瓦烟气余热回收热交换器 上。新系统在热量回收、更高的节能以 及减少排放方面通过三个月以前安装在 位于中国浙江省的国电北仑发电厂已经 得到了证明。 与其它竞争性方案相比，苏威的 Hyflon® PFA提供了更高的温度等级以 及更广泛的耐化学性，从而非常适用于 经受极端的高温和严酷的化学环境的工 A semi-crystalline, fully-fluorinated melt- processable fluoropolymer, Hyflon ® PFA was extruded to form the heat ex- changer tubes that were then assembled into the modules comprising Beijing Xinshiyi’s system. The application signals the first use within China of Solvay’s Hyflon ® PFA in a large-scale 600 MW MGGH heat exchanger. The new system has already demonstrated improved heat recovery, higher energy savings and re- duced emissions since its installation three months ago at Guodian Beilun Power Station located in Zhejiang pro- vince, China. Solvay’s Hyflon ® PFA offers a higher tem- perature rating and broader chemical re- sistance than competitive solutions, which makes it highly suitable to with- stand the extreme heat and harsh chemi- cal environments within industrial-scale heat exchangers. These properties have enabled Hyflon® PFA to demonstrate nearly three decades of proven perfor- mance in heat exchanger applications in more than 30 coal-fired power plants in Europe and China. The material’s out- standing thermal stability and its resis- tance to corrosion and chemicals has supported operating lifetimes of over 20 years. laboration between Evonik and NTEC. Evonik provided the material & product know-how, while NTEC contributed its years of experience in producing these specific filaments for instrument strings,” said Dr. Iordanis Savvopoulos, head of the Granules & Compounds Pro- duct Line at Evonik.
