摘    要:机械不完全燃烧热损失是锅炉运行中的第二大热损失,机械不完全燃烧热损失主要由锅炉飞灰含碳量决定。锅炉飞灰含碳量是反映锅炉燃烧效率的一项重要指标,实时、准确地对飞灰含碳量进行检测是提高锅炉运行效率、降低发电成本的重要手段。通过对国内某电厂的飞灰含碳量的实际测量结果,从经济性和环保角度对目前飞灰含碳量在线监测的必要性作了说明并对目前现有检测方法优缺点加以分析,对目前已经商品化的飞灰测碳仪器加以简介。针对目前电厂常用取样方法存在的问题提出了彻底的解决方案,对未来飞灰测碳技术的发展趋势进行说明,对飞灰含碳量检测技术有一定参考价值。

关 键 词:飞灰含碳量  在线监测  微波  灼烧

Abstract:Mechanical incomplete combustion heat loss is the second biggest heat loss in boiler operation, mechanical incomplete combustion heat loss is mainly determined by the carbon content of the fly ash in the boiler. The carbon content in fly ash of boiler is an important index to reflect the combustion efficiency of boiler, real-time, accurate detection of fly ash carbon content is an important means of improving boiler operating efficiency and reducing power generation cost. By the actual measurement results of the carbon content of fly ash in power plant in China, the necessity of on-line monitoring of carbon content in fly ash from the perspective of economy and environmental protection is described, the characteristics and advantages and disadvantages of existing detection methods in this paper, a brief introduction to the current flying ash measuring instrument. A complete solution is put forward for the problems of common sampling method in power plant, the development trend of carbon technology in the future fly ash is described, and it has a certain reference value for the detection of carbon content in fly ash.
Keywords:carbon  content in  fly-ash, monitoring  on-line, microwave, burning
