摘要
针对汽轮机级间蒸汽泄漏使机组内效率降低的问题,阐述了汽轮机各类汽封的型式和技术特点,并提出了针对某电厂国产600 MW汽轮发电机组汽轮机汽封改进方案。分析了600 MW汽轮发电机组汽封改进后的经济性和安全性。经试验验证,采用该方案改进汽封的机组经济性及缸效率得到了明显提升,机组润滑油质得到了明显改善,同时也提高了机组的安全性。
Aiming at the leakage of interstage steam of turbine which reduces efficiency, this paper introduces all types and technical characteristics of steam seal, proposes transformation plan for steam seal according to the home- made 600 MW turbine in a power plant and analyzes the economy and security of the transformed steam seal of the 600 MW turbine. Experiments proves that the economy of turbine with the transformed steam seal and the cylinder efficiency apparently enhances, with the improvement of the quality of lubricating oil and the security of turbine.
