蒸汽汽轮机.蒸汽纯度

[中文适用范围]： 本技术规范描述了供应给汽轮机的蒸汽化学特性的重要性以及防止蒸汽空间腐蚀和沉积的必要性，以尽量减少汽轮机腐蚀故障或损失的风险 [外文原描述]： Describes the importance of the chemical characteristics of steam supplied to steam turbines and the need to prevent corrosion and deposition in steam space, in order to minimize the risk of turbine corrosion failures or loss of efficiency or output. Is applicable to turbines of all electrical output rating and any exhaust condition, i.e. condensing or back pressure. It is designed for new plant, but may be adapted for use on existing plant. The limits described in this specification are specifically designed to protect the steam turbine. This specification is applicable to steam turbines driven from any source, except geothermal plants in which the turbine is fed direct from the geothermal sources.
