Firing of agricultural residues to produce heat energy leads to char production which is the firing residues. This char is a mixture of unburnt carbon, some metallic oxides and silicon dioxide. While the amount of silicon dioxide present in the char is dependent upon the type of the agricultural residue, the amount of unburnt carbon is determined by air availability and firing temperature. The char remained after firing agricultural residues c...
