Green Coal or HDS (Highly Densified Stalk) is a unique ideally suited green fuel for thermal and power generation and it withstands high fusion temperature. It is derived through reverse botanical process with high calorific value up t o 4700 K Cal/ K g) â?¢ Fuel is densified further with a specific temperature gradient enabling to achieve desired hardness to avoid the loss during transportation. Uniform CORE TO SURFACE hardness and density leads to smooth burning thereby ensuring smooth combustion and heat generation. One of the unique features of this HDS is under controlled combustion at elevated fusion temperatures enables high calorific value fuel output resulting in better yield values attributes of this fuel. (Nearly 30% savings against Coal/Bio mass briquette) It has 5% moisture unlike urban waste which has 47% Ash content below 5
