摘要
Abstract
Back-pressure steam turbine are widely used in thermal power plants due to their advantages of simple structure,achievable cascade energy utilization,and high efficiency.Taking a 57MW high-temperature and high-pressure back-pressure steam turbine generator unit in a certain power plant as an example,in this paper,the safety and economic problems existing after its commissioning are discussed,such as cylinder deflection during the start-up process,long start-up time,steam-flow-induced vibration during the load-carrying process,low thermal efficiency,and output shortfall.Through the implementation of through-flow efficiency improvement transformation of the steam turbine,the above-mentioned problems have been completely solved,ensuring the efficient and safe operation of the steam turbine generator unit.关键词
