YL3000型烟气轮机是用于催化裂化能量回收装置的关键设备,它不同于一般的燃气轮机。由于烟气中含有催化剂固体颗粒,如何在烟气轮机的结构和流通部分的设计上考虑减小带有固体颗粒的烟气对动叶片的冲蚀,这就形成了烟气轮机设计的独特的特点。另外,由于其单级焓降较大,要求在小u/C_0下能有较高的效率,这也是通流设计中的特点之一。国外,催化裂化能量回收的研究工作已有二十多年的历史,但烟气轮机的设计和制造至今仍被美国英格索尔一兰德、埃利奥特和西德的G.H.H公司所垄断。我国自1974年开始进行烟气轮机的
YL3000 type gas turbine is a key equipment for catalytic cracking energy recovery unit, it is different from the general gas turbine. Since the flue gas contains catalyst solid particles, how to reduce the erosion of the moving blades by the flue gas with solid particles in the design of the structure and the circulation part of the flue gas turbine forms a unique Features. In addition, due to its large single-stage enthalpy drop, it is required to have higher efficiency under small u / C_0, which is also one of the characteristics of the through-flow design. Abroad, the research on energy recovery of catalytic cracking has been going on for more than 20 years, but the design and manufacture of flue gas turbines are still monopolized by the GHH companies of Ingersoll Rand, Elliot and West Germany . China started to carry out the gas turbine in 1974
