Biomass fuels is a wide sources and renewable green energy. 

Characteristics:      
1. Higher LHV: General Biomass fuel heat’s LHV is 3900 ~4800kCal/kg, the highest maybe up to 7000-8000 kcal / kg;
2. Higher purity: 75-85% carbon, 3-6%ash, 1-3% moisture;
3. No sulfur and phosphorus dioxide will be produced in combustion process, thus will no pollution to the environment;
4. Cleaning, easy feeding;
5. Only a little ash slag will be produced after combustion.  And the ash is a high quality of organic potash fertilizer, may be recyclable used.
