燃煤电厂烟气中SO_3控制技术及测试方法探讨
|
摘要
探讨了燃煤电厂烟气中SO_3控制技术及测试方法,旨在为我国相关技术的研究及测试标准的制定提供参考依据。详述了烟气中SO_3的燃烧前、燃烧中及燃烧后控制技术;燃煤烟气中SO_3的测定主要应用先采样后分析SO_4~(2-)的方法,SO_3的采样主要使用异丙醇吸收法和控制冷凝法,SO_4~(2-)则主要使用容量滴定法、分光光度法及离子色谱法进行分析。此外,分析了不同SO_3控制技术及测试方法的优缺点,提出了可行的燃煤电厂烟气中SO_3控制技术路线。
Control technology and determination methods of SO_3 in flue gas from coal-fired power plants were studied,aimed at providing reference for the control technology and determination standard compilation of SO_3 in China. The pre-combustion,incombustion and post-combustion control technology of SO_3 from flue gas were detailed. Determination of SO_4~(2-)after sampling was the dominating method of determining SO_3 from coal-fired flue gas. Alcohol absorption method and control condensation method were the main methods of sampling SO_3. SO_4~(2-)was mostly determined by means of volumetric titration,spectrophotometry and ion chromatography. Advantages and disadvantages of different control technologies and determination methods of SO_3 were also researched. The appropriate technical route of SO_3 control technology was also proposed.
