| 摘 要： | 低低温电除尘技术是电除尘新技术,不仅可以提高电除尘器的除尘效率,改善电除尘器对煤种的适应性,还可除去烟气中大部分的SO3,已经成为日本燃煤电厂烟气治理的主流。烟气的灰硫比(D/S)是低低温电除尘器选型设计中的一个重要参数,是电除尘器是否会受到低温腐蚀的评判标准。对烟气灰硫比的定义,计算公式的推导,中国几种代表性煤种的灰硫比,以及灰硫比与腐蚀和提效幅度的关系作了深入的分析。为我国低低温电除尘器的研究和应用推广提供参考。

| Abstract: | Low-low temperature electrostatic precipitator ( LLT-ESP) technology is a new technology and has become themainstream method of smoke-gas treatment in Japan，as it can improve the collection efficiency of PM and SO3 ． D/S ratio( Dust /SO3 ratio) which means the ratio of PM concentration ( mg /m3 ) to SO3( mg /m3 ) ，is one of the most importantparameters in ESP selection and the measure of low temperature corrosion happens or not． It was analyzed the definition andformula of D/S ratio and calculated some representative coals in China． The relationship of D/S ratio to corrosion and theincrease of efficiencies was given，which provided reference for study and application of LLT-ESP in China． |
