摘要(Abstract)：

采用热重分析仪对温州电厂4个常用煤种进行了不同氧浓度的燃烧特性试验,分析了氧浓度对煤粉着火和燃尽的影响。结果表明,随着氧浓度的提高,4个煤种的燃烧和着火均有不同程度的提前,且其变化规律有一定差异,神木类混煤对氧浓度变化比优混类混煤更为敏感。
This paper performs the tests on combustion characteristics of 4 common types of coal under various oxygen concentranous using thermogravimetric analyzer in Wenzhou power plant.The result shows that with the oxygen concentration increasing,the ignitability and burnout characteristics of four samples are both improved in varying degrees with different varianon rules.The shenmu coals are much more sensitive than mixed coals to the changes of oxygen concentration.
