Calcination Wikipedia
Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone through combustion to yield calcium oxide (quicklime) This calCalcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances However, calcination is also used to mean a thermal treatment process in the absence or Calcination WikipediaThe calcining process is composed of the petroleum coke charger (black), fluidized bed calciner with electrodes and nitrogen supply (red), and gas cleaning system (yellowgold) The waste heat utilization system (or advanced CHP) is composed of the combustor/boiler (purple), coke cooler (blue), and generator (blueviolet)Utilization of Process OffGas as a Fuel for Improved
