摘要

为确切了解某电厂锅炉及其辅机对混煤掺烧的适应性情况，并为其运行提供经验，在该锅炉上进行了澳大利亚烟煤(澳煤)与国内优混烟煤(优混)的掺烧试验

并根据美国机械工程师协会(ASME)标准和中国国家标准(GB)计算得出了不同掺烧工况下的锅炉反平衡效率；基于影响锅炉效率的7个主要参数

进行了测试结果的不确定度分析。结果表明:在ASME标准下

全烧优混煤和掺烧50%澳煤的锅炉效率分别为93.73%和93.83%；在GB下

全烧优混煤和掺烧50%澳煤的锅炉效率分别为93.10%和93.28%。掺烧澳煤后锅炉效率略有提升

但相差不大。在ASME标准下

全烧优混煤和掺烧50%澳煤的锅炉效率扩展不确定度U95(η)分别为0.210%和0.218%；在GB下

全烧优混煤和掺烧50%澳煤的锅炉效率扩展不确定度U95(η)分别为0.244%和0.256%。锅炉效率不确定度很小

表明锅炉效率测量试验准确度很高。
