对高挥发分进口煤的安全燃烧研究及评估

Burning Security Research and Evaluation for High Volatile Imported Coal

为了适应国内煤炭市场变化 ,降低发电用煤成本 ,拓宽煤炭供应渠道 ,公司倡导试用有很高经济价值的印尼煤。由于印尼煤具有高热值、高挥发分、低灰分特征 ,在极易燃烧的同时 ,也存在易自燃、自爆的危险。通过对杨柳青、三河、石洞口二厂、湄洲湾等电厂的调研 ,完善制粉系统防爆措施。目前已安全燃用几十万t,没有出现任何异常情况。

For adapting to the change of national coal market, reducing the cost of the power-generated coal and expanding the coal-perveyed chanel, HPI encourages us to use Indonesia coal which has higher heat value, higher volatile, less ash component. It's very incendive and, mean while, has danger of self-ignition and explosion. Via the research on Yangliuqing, Sanhe, Shidongkou No.2, and Bay Meizhou Power-plants. the author has been consummating the explosion-prevented measure for the milling systems. By now, several hundred-thousand tons of those has been burning without any abnormity.
