煤渣

Coal dust is a fine powdered form of coal, created by the crushing, grinding, or pulverizing of coal. Due to the brittle nature of coal, coal dust (fugitive dust) is common and easily created during mining, transportation and even by mechanically handling coal.

The grinding of coal to dust before combusting is generally done to improve the speed and efficiency of burning, also simplifying its handling.

悬浮在空气中也被认为具有潜在危害:

在封闭的环境中,细小悬浮颗粒会迅速燃烧或爆炸危险。过量吸入粉煤会导致慢性肺部疾病。
