NOVELTY - A completely-combustable bio-particle fuel comprises 73-77 pts. wt. crop straw, 21-23 pts. wt. falling leaves, 21-23 pts. wt. sawdust, 21-23 pts. wt. bagasse, 5-7 pts. wt. fermenting bacteria, 1.4-1.8 pts. wt. sodium selenite and 0.2-0.4 pt. wt. graphene. USE - Completely-combustable bio-particle fuel used as fertilizer. ADVANTAGE - The completely-combustable bio-particle fuel is economical, and promotes generation of fermentation bacteria metabolite, improves porosity of raw material, and enlarges contact area with oxygen raw material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of completely-combustable bio-particle fuel, which involves crushing crop straw, defoliating, adding sawdust and bagasse, obtaining crushed material, adding same amount of water to pulverized material, mixing uniformly, adding 1/2 fermenting bacteria, fermenting at 30-32 degrees C for 40-48 hours, obtaining fermentation material, adding sodium selenite to primary fermentation material, mixing, adding remaining fermenting bacteria, fermenting at 24-26 degrees C for 4-5 days, obtaining secondary fermentation material, adding graphene to secondary fermentation material, mixing, freezing to the moisture content of 13-15%, obtaining dry material and extruding-molding.
