In most coal dust explosions the air speed exceeds 200 miles per hour In fact a coal dust explosion will generally die out if the air speed is less than 100 miles per hour 150 feet per second The maximum explosion pressure developed is about 90 psig for Pittsburgh Seam coal

As such coal storage during cement manufacturing is an important component to consider in hazard analysis Among the various causes of coal fires spontaneous combustion during storage results in a large number of losses Spontaneous combustion is caused by adsorption of oxygen at the outer and inner surface of coal which results in oxidation

Oct 06 2005 · Cement dust iswas used to suppress fires and coal dust explosions in coal mines Like stated above Ive never seen any measures taken around cement storage silos that would suggest an explosive potential The one thing missing is there is no organic material available

When combustible dusts ignite there are often two explosions known as primary and secondary explosions The primary dust explosion is the first explosion It occurs when there is a dust suspension in a confined space such as a container room
