煤粉与水煤浆焦炭颗粒燃烧速度的分析和比较

Analysis and Comparison of the Combustion Speed of Coal Water Slurry and Pulverized-coal Coke Particles

通过茂名热电厂 2号燃用水煤浆锅炉与半山电厂 5号煤粉炉满负荷燃烧试验 ,对水煤浆 (CWS)与煤粉焦炭颗粒进行燃烧速度的分析、比较。通过SEM扫描电镜 ,BET氮吸附试验和粒度分析仪 ,对燃烧试验的飞灰样进行试验分析 。

Through the full-load combustion tests of a coal water slurry-fired boiler No. 2 at Maoming Thermal Power Plant and a pulverized coal-fired boiler No. 5 at Banshan Power Plant an analysis and a comparison was conducted of the combustion speed of coal water slurry (CWS) and pulverized-coal coke particles. With the help of a scanning electron microscope and by way of a BET nitrogen adsorption test and by using a granularity analyzer the fly ash samples of the combustion test were studied and analyzed. This is followed by a discussion of the causes, which may have led to the divergence in combustion speed of CWS and pulverized-coal coke particles.
