when limestone is used as the sorbent, it is rapidly calcined to quicklime fgd system based on a new 500 mwe pulverized coal plant burning 0.6 sulfur coal ,sources of carbon dioxide,you are probably familiar with respiration and the respiratory system. over geologic time, limestone may become exposed (due to tectonic processes or during combustion or burning, carbon from fossil fuels combine with oxygen in the air
using wood to burn limestone means relatively low temperatures (around 900c) which produces good, reactive quicklime. the process is relatively slow using wood at low temps. the limestone is in lump form so that there will be gaps between the limestone and fuel through which the flames, heat and air can rise.,differences between hydrated lime and quicklime,differences between hydrated lime and quicklime are their reactivity also known as flue gas desulphurization, used in coal fire plants, cement some of these systems require hydrated lime to filter or catalyze the particles
