【摘要】 <正> 一、引言 能源的合理利用是四化建设中的重要课题,煤占我国能源资源的70％,研究煤的燃烧具有重要意义。而固态炭的燃烧在煤的燃烧中起着主导作用。本文的内容就是关于碳粒燃烧特性的实验研究和分析,即对处于室温下、不同氧浓度静止环境中的98～170μm碳粒,用脉冲激光点燃,记录其燃烧的全过程,并把实验结果与理论分析对比。从中探讨了:更多还原

【Abstract】 Experimental data of carbon particles (98-170 μm) ignited by a pulsed laser in quiescent oxygen environment are presented. The experiment is conducted in O2-N2 mixtures at room temperature, the pressure of 1 atm, oxygen mass fraction 0.8-1.0. Photography and two-color optical pyrometry are used to measure the burning duration and the surface temperature history of the measured particle. The experimental results have shown that it is appropriately to study the combustion history and the kinetics of single particles with the laser-ignite method. The method can also be used to deal with the kinetics of oxidation of coal and metal particles.更多还原
