石油产品. 燃气轮机燃料热氧化安定性的测定

[中文适用范围]： 本文件规定了对燃气轮机燃料在燃料系统内沉积分解产物的倾向进行评级的程序。 它适用于中间馏分油和宽馏分燃料，特别针对航空燃气轮机燃料的性能进行了规定。 测试结果表明燃气轮机运行期间燃料的热氧化稳定性，并且可用于评估当液体燃料在指定温度下接触加热表面时形成的沉积物的水平。 该方法也适用于由 ASTM D7566[1] 和 Def Stan 91-091[2] 范围内定义的传统和合成混合组分组成的航空涡轮燃料。 注：为了方便那些使用旧仪器的人，非 SI 单位和重新计算的数字在括号之间给出，它们更合适。 [外文原描述]： This document specifies a procedure for rating the tendencies of gas turbine fuels to deposit decomposition products within the fuel system. It is applicable to middle distillate and wide-cut fuels and is particularly specified for the performance of aviation gas turbine fuels. The test results are indicative of fuel thermal oxidation stability during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface at a specified temperature. This method is also applicable to aviation turbine fuel that consists of conventional and synthetic blending components as defined in the scope of for instance ASTM D7566 [1] and Def Stan 91-091 [2] . NOTE For the benefit of those using older instruments, non-SI-units and recalculated numbers are given in between brackets where they are more suitable.
