富氧燃烧空分制氧技术研究与应用
|
摘要
与传统深冷空分工艺相比,富氧燃烧空分系统具有需氧量大、压力低、氧纯度低、动态响应快等特征。富氧燃烧电厂空分装置厂用电率高达30%以上,空分工艺的选择对降低富氧燃烧电站的能耗和成本至关重要。文章对富氧燃烧空分技术研究进行了综述,分析比较了富氧燃烧空分工艺流程和变负荷调节方式,介绍了目前世界上富氧燃烧电站空分技术的应用,为富氧燃烧空分工艺流程的选择和降低富氧燃烧发电系统能耗提供了初步的参考。
The oxygen requirements for oxyfuel combustion power plant are usually different from those of other oxygen users. The amount of oxygen required is large,the oxygen pressure and purity is low,and fast transient response is also needed. Since the auxiliary power consumption ratio of the Air Separation Unit( ASU) for oxyfuel combustion power plant is as high as 30%,the selection of ASU is very important for the reduction of energy consumption and cost. This paper has reviewed the oxygen production technologies for the oxyfuel combustion,and has analyzed different air separation processing and off-design adjustment measures. Also,several typical applications of the oxygen production technologies for the oxyfuel combustion have been stated. This paper provides reference for the selection of ASU in the oxyfuel combustion power plant.
