Emergency inerting systems for coal Global Cement

Emergency inerting systems for coal Global Cement

Oct 21, 2011 In the case of coal-grinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component - O 2. This fact has given rise to inerting systems that rely on the use of inert gases.

How to Calculate the Coal Quantity Used in a Power Plant

Oct 15, 2009 Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.
