前言

本标准是GB/T14100-1993((燃气轮机验收试验》的增补件，它等同采用了国际标准化组织燃

气轮机技术委员会ISO/TC192发布的ISO2314;1989燃气轮机验收试验》的增补件Amendment

1;1997(E)《联合循环电厂验收试验})(英文版)。

本标准在以下条、段中对原国际标准作了修改:

118.1.1排气焙”中的“注:作为信息资料，可以使用下列表格或其他适当的表格:”增补了我国吴仲

华编制的《燃气热力性质表》，其理由是:该表在国际上早已被认可，并得到了广泛的使用。

"8.3典型的通用修正曲线”中图9原文为:"CorrectioncurveofCC-heatratevs.relativehumidi-

ty(coolingtower)"。根据曲线内容的排列以及图9横坐标的刻度，现改为:“联合循环热耗率随环境温

度变化的修正曲线(冷却塔)。”

本标准由中国电器工业协会提出。

本标准由全国燃气轮机标准化技术委员会(CSBTS/TC259)归口。

本标准由南京燃气轮机研究所、南京汽轮电机(集团)有限责任公司、上海发电设备成套设计研究

所、浙江省电力设计院、苏州高达热电厂和杭州锅炉厂负责起草。

本标准主要起草人:何语平、涂庆国、胡星辉、杨家强、王兴邦、杨道刚、金平。

联合循环发电装置验收试验

范围

1.1为了确定和/或考核联合循环发电装置的输出功率和热效率，需要进行验收试验。本标准为验收

试验的实施和报告的编制规定了标准程序和规则。本标准为验收试验的测量方法提供了信息，也为试

验条件下获得的结果按照保证条件或其他规定的条件进行修正的方法提供了信息。

1.2验收试验的目的是确定与性能保证值相关的联合循环的性能，如:

a)属于同一个合同的整套发电装置(燃气和蒸汽部分)在规定运行条件下的输出功率;如果燃气

轮机部分是由一个单独的合同所提供，则仅为蒸汽循环部分(底部循环)在规定运行条件下的

输出功率。

b)在规定的运行条件下的热效率、热耗率或燃料消耗率(只有当合同涉及整个联合循环时)。

1.3本标准适用于不补燃的联合循环发电装置。经适当修改，也可作为一般导则用于补燃的联合循环

发电装置或其他型式的联合循环。本标准不适用于联合循环发电装置的各组成部分分属于不同合同的

情况，因为这种情况下每个设备都有其相应的标准可适用。

2规范性引用文件

下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注日期的引用文件，其随后所有

的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究

是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本标准。
