摘　　要：低真空循环水供热能够实现能源的梯级利用,具有节能、环保、高效能源利用等优点,有良好的推广应用价值和发展前景。但此项技术的应用会对汽轮机带来一系列问题和安全隐患,影响机组的安全性。文中主要从主机设备安全的角度出发,深入分析应用此技术对汽轮机带来的影响,详列影响因素并提出解决办法,为今后汽轮机低真空改造提供指导性帮助。Supplying heat with low vacuum circulating water can realize cascade utilization of energy with advantage of energy saving, environmental protection and high efficiency which has a well application value and prospect. But application of this technology can bring a series of problems and hidden safety dangers which will affect the safety of unit. This article deeply analyzed from the view of safety the effect of this technology on steam torbine, demonstrated in detail the influence factors and gave good solutions on them. This article will give guide instructions on low vacuum modification of steam turbine.
