NOVELTY - The method involves obtaining (1004) preset value for initial ash amount of biomass on a dry basis using formulation of fuel produced from the biomass. The information regarding a preset higher heating value of fuel is accessed on dry basis information regarding predetermined carbon to oxygen fuel ratio. The higher heating value of fuel is computed using a microprocessor on dry basis from information regarding predetermined ratio of carbon to oxygen of fuel, when preset ratio of carbon to oxygen is accessed and computed according to preset expression.    USE - Method for producing fuel from biomass such as agricultural wastes. Uses included but are not limited to agricultural wastes such as wood, guinea grass, rice straw, sugar cane leaves, cotton stalk, mustard stalk, pine needle, coffee husk, coconut husk, rice husk, mustard husk, weed straw, corn stover, sugar cane bagasse, millet stalk, pulses stalks, sweet sorghum stalk, nut shell, animal manure, guar husk, acacia totalis, julia flora, jatropha residue, wild grass, pigeon beans, pearl millet, barley, dry chili, gran jowar, linseed, maize/corn, lentil, mung bean, sunflower, till, oil seed stalk, pulses/millets, black gram, sawan, soybean stalks, cow gram, horse gram, finger millet, turmeric, castor seed, meshta, sannhamp, and hemp.    ADVANTAGE - The higher heating value of fuel is computed using a microprocessor on dry basis from information regarding predetermined ratio of carbon to oxygen of fuel, when preset ratio of carbon to oxygen is accessed and computed according to preset expression, such that the unique system design and unique fuel production process can be developed effectively. The fuel with specific and desirable properties can be produced at less time consumption. The cost can be reduced considerably.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) process for facilitating production of fuel on dry basis; and    (2) system for facilitating production of fuel.    DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the fuel producing process.
