Explosion protection for coal grinding plants. What

2021-8-24  The coal mill is operated as an air-swept mill and “blows” directly into the combustion zone of the steam boiler, via a pipeline connection. In case of an explosion, normally as consequence of ignition within the mill chamber, there will be explosion propagation towards the boiler. The combustion “cloud” will propagate to where it finds ...

Coal Dust Explosion Prevention and Protection Based on ...

2017-1-24  coal dust explosion occurred at Dongfeng mine in Qintanhe and caused 171 deaths. Therefore, it is very significant to prevent and mitigate dust explosion intrinsically with the thinking of inherent safety. Overton said that this thinking was helpful to prevent and control dust explosion in the process industries. Amyotte have done many case studies about the application of inherent safety principles to dust explosion
