Significant accumulations of coal dust throughout the plant contributed to the severity of the incident. Despite the history, coal dust explosion incidents continue to occur, for example in August of 2008 an unplanned outage at a newly commissioned Western power plant lead to an explosion that ...
explosion is discussed. Preventive techniques comprising methane drainage, use of permissible equipment, mixing inert material, such as limestone dust, with coal dust to render it inert are explained. Finally, the use of stone dust barriers to contain the explosion within a section is presented. ...
power plants[4]. Simple control is also responsible for high fuel consumption, poor dynamic response, and high operating cost. Further, the mill performance and availability is also influenced by some common mill faults like mill choking, coal hang up in mills, fire or explosion, and wear in...
The risk of explosion can be reduced by adequate ventilation during mining or by prior removal of coal-bed methane. Reflectivity An important property of coal is its reflectivity (or reflectance)—i.e., its ability to reflect light. Reflectivity is measured by shining a beam of monochromatic ...
(and they were almost all men) worked to haul hundreds of millions of tons of coal out of the ground. The coal miners helped build America, but it was brutal work — if a coal-gas explosion didn’t kill them, black lung would. The work put dinner on the table and pride in their ...
MONTGOMERY, Ala. (AP) — Alabama Power Co. will pay $75,000 in fines and stop burning coal in a unit that released too much hydrochloric acid at a generating plant north of Mobile under an agreement with state environmental regulators.

There is no doubt that several decades ago, clean air regulations caused power generation to begin shifting away from coal and toward natural gas. But in recent years, the most significant pressure by far is price. The chief reason for this was the explosion of shale gas production, which cr...
