coal dust explosions in power plants

Dust explosion protection in a hard coal-fired power plant ...

dust in mining has been well known for years. In the power plants, the hard coal is transported to the furnaces on long conveyor belts (Fig-ures 2 and 3). The coal is largely so coarse-grained that there is no immediate risk of dust explosion. However, unavoidable abrasion across the whole transportation path, from conveying to the power plant ...
