摘要
国产最大功率烟气轮机--33 MW单级烟机,于2003年7月在兰州石化分公司3.0 Mt／a重油催化裂化装置"四机组"投入运行。该烟机具有膨胀比大,跨音速、焓降大,转动件的设计应力值比较大等特点。着重介绍了YL33000A烟机的技术特点和创新点;介绍了高温合金材料的选用情况以及涂层、主轴用材料的选用情况;还介绍了这些材料技术标准的制定情况等。
The largest domestic flue gas expander, 33 MW single stage expander was put into use in the 60 000 b/d RFCC unit of Lanzhou Petrochemical Company on July, 2003. The flue gas expander is characterized by big expansion ratio, beyond velocity of sound, high enthalpy drop and the design stress values of moving parts are relatively large. Technical features of YL33000A expander are expounded as well as the selection of high temperature alloy material and the material for covering and chief shaft. In addition, technical standard making of the material is introduced.
