燃煤电厂超低排放技术方案应用

中国煤种复杂多样，中高灰、中高硫煤在大型燃煤机组应用广泛，在火电污染物排放标准日益严格的背景下，讨论中高灰、中高硫煤种的超低排放技术路线的适用性以及进行技术路线的总结分析是非常必要的。对3台燃用中高灰分和中高硫分煤种的燃煤机组的超低排放技术路线的应用情况进行了分析。运行数据结果表明，燃用中高灰、中高硫分的煤种选择适当的技术路线可以使NOx、SO2和粉尘达到超低排放标准。提出了燃用中高灰分和中高硫分煤种机组的超低排放技术路线的选择建议。

Application of Ultra-Low Emission Technical Roadmaps of Coal-Fired Power Plants

There are a variety types of coal in China, of which those with medium/high ash and medium/high sulphur contents have been widely used in large coal-fired power plants. Under the background of increasingly stringent pollutant emission standards, it is absolutely necessary to explore and analyze the technical roadmaps of ultra-low emission adaptable to these types of coal. This paper conducts the analysis on the applications of ultra-low emission techniques in three coal-fired power plants fueled by medium/high ash and medium/high sulfur coal. The results show that, it is possible for such plants to make the NOx, SO2 and dust emissions reach the ultra-low emission standards by selecting appropriate technical roadmaps. In this paper the advice is also provided on how to choose the ultra-low emission technical roadmaps for coal-fired power plants using medium/high ash and medium/high sulfur coal.
