【摘要】 利用NETZSCHSCHEMESTA 40 9型示差热天平 ,对烟煤的 3个单煤种和 8个混配工况进行了热分析试验。结果表明 ,烟煤混煤的燃烧特性基本处于组分煤种之间。通过不同升温速率试验 ,发现高升温速率条件下 ,燃尽时间短 ,燃烧猛烈 ,燃尽温度较高更多还原

【Abstract】 This paper completed the thermoanalysis experiment of three single bitumci nous coal and eight blending coals by NETZSCH SCHEME STA 409 thermobalance.The results show that the combustion character of bitaminous blending loals coals is between fractional coal basically.By different temperature rise rate test,it is discovered that burn out time is shorter,combustion fieriness and burn out temperature is higher in high temperature rise rate.更多还原
