Abstract

The invention provides biomass briquette fuel and a preparation method thereof. The biomass briquette fuel is prepared from the following components in parts by weight: 40-50 parts of crop herbal byproducts, 30-40 parts of PP wood-plastic wastes, 35-50 parts of forestry wood byproducts, 0.5-3 parts of a combustion adjuvant and 0.5-3 parts of an anti-coking adjuvant, wherein the components are extruded and molded to prepare the biomass briquette fuel. According to the preparation method, the raw materials are screened and combined, raw materials causing secondary pollution are prevented from being used, and the prepared biomass briquette fuel has a preparation calorific value being 5200-6000kcal/kg. The biomass briquette fuel has the characteristics of high calorific value, easiness in ignition, coking prevention and low emission.

Description

technical field [0001] The invention relates to the technical field of bioenergy, in particular to a biomass briquette and a preparation method thereof. Background technique [0002] At present, biomass solid fuel is mainly made of various straws, sawdust and other agricultural and forestry wastes, poultry and livestock manure, traditional Chinese medicine residue, printing and dyeing sludge, waste plastic rubber, urban organic waste, etc. as raw materials. Due to the large number of biomass raw materials, the physical and chemical properties of various types are quite different. Although biomass energy has considerable potential, there are still some problems, mainly reflected in: [0003] (1) low calorific value; such as patent CN105482866A provides a kind of biomass fuel, including the following raw materials in parts by weight: 100-120 parts of straw, 5-10 parts of metakaolin, 20-50 parts of charcoal, 10-15 parts of turpentine , 1-3 parts of combustion aid: potassium pe...
