19、ents and contaminants.GE重型燃气轮机能够燃烧种类广泛的气体燃料，如表1所示。这些气体燃料的特性由于相应的反应物和惰性成分的浓度不同而变化非常之大。为了保护燃气轮机，高效且无故障地燃烧这些燃料，本规范对其物理特性、成分及污染物划定了许用范围，Table 2a specifies the allowable limits for the fuel properties and constituents and Table 2b lists the limitation on contaminants. These tables provide a screen for fu

Fuels that fall outside of these limits may be acceptable for specific applications e.g. a high hydrogen fuel can be used with standard combustors in most cases.

21、污染物的限额。这些表将所有结构尺寸和燃烧器类型都适用的燃料都展示出来了。超出这些限额的燃料可以用在特定的场合，例如在大多数情况下，含氢量高的燃料可以结合标准的燃烧器使用。这些燃料更详细的评价可以联系GE获得。Table 3 identifies the acceptable test methods to be used for determining gas fuel properties shown in Tables 2a and 2b.表3区别了确定表2a和表2b中所列气体燃料特性采用的测试方法。TABLE 1 表1FUEL GAS CLASSIFICATION 气体燃料分类FUEL燃

31、ce metal limits. Sulfur levels shall be considered when addressing HRSG Corrosion, Selective Catalytic Reduction (SCR) Deposition, Exhaust Emissions, System Material Requirements, Elemental Sulfur Deposition and Iron Sulfide. (refer to Section IVD)本规范没有对气体燃料中硫的数量加以限制。经验表明燃料中硫的体积含量水平达到1%时对氧化腐蚀率影响也并不大

32、。热燃气通道部件的热腐蚀是通过规定微量金属的限额来控制的。当提及余热锅炉腐蚀、选择性催化还原沉淀物、排气释放、系统材料要求、硫单质沉淀和硫化铁时应考虑含硫水平。（参见IVD部分）13.

GE will review these on a case-by-case basis.盐水中来的钠和钾是天然气中常见的仅有的腐蚀性微量金属污染物。Na/K =28是标定的海盐比例。在气化和气体处理时也许会发现其他微量金属污染物。GE会逐一加以审查。15. The fuel gas delivery system shall be designed to prevent the ge

(See section IVA)燃气输送系统设计用来防止微粒生成或进入燃气轮机气体燃料系统。这包括但不局限于从微粒过滤器到燃气轮机设备入口的微粒过滤器和无腐蚀（例如：不锈钢）管道。燃气轮机运行前，燃气管道系统要正确清扫、冲刷和维护。（见IVA部分）16. The fuel gas supply shall be 100% free of liquids. Admission of liquids can result in combustion and/or hot gas path component damage. (See section IIIC)燃气供应绝不能有一点液体。液体的进入会造成燃烧室和热燃气通道组件的损害。（见IIIC部分）TABLE 3 表3TEST METHODS FOR GASEOUS FUELS 气化燃料的测试方法PROPERTY 特性 特性METHOD 方法 Gas Sampling Procedure 气体取样过程Gas Composition to C6+ (gas chromatog
