Fire and Explosion Prevention in Coal Pulverizing Systems
Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

Blast Furnace - an overview | ScienceDirect Topics
Integrated coal-fueled steel mills accounted for ∼60% of the 1.4 Gt of global steel produced in 2008, consuming 15–18 GJ per t-steel produced and emitting a global average of ∼1.4 t-CO 2 per t-steel produced. In the first stage of the steelmaking process, high-grade coal (anthracite) is used to fuel a blast furnace in which iron is extracted by reduction from the ore hematite (Fe 2 O 3 ...
