Coal's Spontaneous Combustion Problem - Sightline

11.04.2012· spontaneous combustion in coal, as an underwriter, is a very interesting topic.I have come across a claim pertaining to S.C loss in coal stored at krishnapatnam port Andhrapradesh India. The coal of very high volume of 69000 M.Ts stored as a single heap. Such a hugh heap developed HOT- SPOTS at many places and S.C ocured and fire fighting eforts are futile. After going through the above,Characterization of some Indian coals to assess their,,01.01.2016· Indian coals have low-sulphur content except in North-Eastern coalfields, and the pyrite is one of the key factors of susceptibility of coal to spontaneous combustion. The result shows that NEC coals have sulphur content less than 3%, which should not reflect on spontaneous combustion of coal. Additionally, nitrogen content in the collected coal (∼4%) does not relate to the rank of coal, and therefore it would not have any effect on spontaneous combustion. The classification of the coal,EH-93-4 The Fire Below: Spontaneous Combustion in Coal,,Preventing Spontaneous Combustion in Stored Coal Hugh quantities of coal are stored in bunkers, silos, hoppers and open air stockpiles. How susceptible such stocks of coal are to fire from spontaneous combustion depends on a number of factors, from how new the coal is to how it is piled. Recommendations: o Know your coal. Anthracite (sometimes called eastern coal) has a
