Abstract

The invention relates to new biomass energy granules and a preparation method thereof, and belongs to the technical field of comprehensive utilization of new biomass energy. The new biomass energy granules are environmentally friendly, high in calorific value, high in smoothness and high in compactness. According to the technical scheme, the new biomass energy granules are prepared from the following raw materials in parts by weight: 40 to 60 parts of maize straw, 10 to 20 parts of pine needle, 10 to 20 parts of sawdust, 5 to 15 parts of poplar branch, 10 to 15 parts of willow branch, 5 to 15 parts of locust tree branch, 5 to 10 parts of elm branch, 5 to 10 parts of macker, and 10 to 20 parts of chicken manure, wherein the sawdust is miscellaneous tree sawdust. The preparation method comprises the steps of crushing the raw materials into powder; mixing in ratio to obtain primary materials; drying the primary materials to obtain dried materials; controlling the water content of the dried materials to be 15 to 18%; feeding the dried materials into a granulating machine; extruding at high temperature of 90 to 150 DEG C to obtain the new biomass energy granules.

Description

technical field [0001] The invention relates to a biomass new energy granular material and a preparation method thereof, belonging to the technical field of comprehensive utilization of biomass new energy. Background technique [0002] Biomass new energy refers to fuel ethanol and biodiesel produced from biological resources, which can replace gasoline and diesel produced from petroleum, and is an important direction for the development and utilization of renewable energy. Biomass fuel refers to the fuel that is directly used by compression molding of crop straw, wood chips, sawdust, peanut shells, corn cobs, rice husks, branches, leaves, and hay. The production process does not add any additives and binders. Biomass new energy is a renewable clean energy. Broadly speaking, biomass energy is a manifestation of solar energy. At present, many countries are actively researching and developing biomass energy. Biomass energy is stored in organic matter that can grow, such as ...
