Abstract

The invention discloses an oily biomass wood dust particle fuel formula with high combustion value and a preparation method thereof. Particles comprise the following compounds according to parts by weight: 80-90 parts of wood dust, 6-12 parts of dregs of a decoction, 1-4 parts of peanut shell, additive agent and the like; and the preparation method comprises the steps of crashing, drying, mixing, pressing, cooling and the like. The thermal value, combustion rate and fuel efficiency of biomass fuel are greatly increased, so that better compression ratio is obtained; and simultaneously, the blackness of exhaust smoke is reduced below Ringelmann 1, the abrasion of forming cylinder and spiral shaft is further reduced, and the service life of the machine is prolonged.

Description

technical field [0001] The invention belongs to the field of fuel technology, in particular to a biomass fuel formula and a preparation method thereof. Background technique [0002] Biomass fuel is a fuel that includes organic matter such as plant material and animal waste, and is a new name for the oldest fuel used by humans. The more economical biomass fuel is biomass briquette fuel, which is mostly block fuel produced by processing stem crops, peanut shells, bark, sawdust and solid waste (furfural slag, edible fungus slag, etc.), and its diameter is generally 6-8 mm in length, 4-5 times its diameter, broken rate less than 1.5%-2.0%, dry basis moisture content less than 10%-15%, ash content less than 1.5%, sulfur content and chlorine content both less than 0.07 %, the nitrogen content is less than 0.5%. [0003] Since the 1980s, my country has been committed to the technical research of biomass fuel preparation. During the "Seventh Five-Year Plan" period, Nanjing Forestr...
