Problems solved by technology

Adding other binding materials to straw raw materials not only increases the production cost of pellet fuel, but also produces certain pollutants after the pellets are burned.
[0008] In addition, since the calorific value of crop straw is lower than that of wood, the calorific value of pellet fuel made from crop straw is lower than that of wood pellets. In order to increase the calorific value of straw pellet combustion and meet certain calorific value requirements, sometimes it is necessary to add certain A large amount of additives with high calorific value such as diesel oil, coal or carbon powder, but this will also produce pollutants

specific Embodiment

[0021] A specific embodiment of the present invention: a biomass composite granular fuel, which uses crop straw with low lignin content and calorific value and woody material with high lignin content and calorific value as raw materials, and the crop straw and woody material are respectively Carry out crushing and drying to make the moisture content reach 10%-16% (weight), then put the straw scraps and wood scraps into the granulator and mix them thoroughly. The pressing system is formed, cooled, and packaged to make granular fuel. The temperature during pressing is 100°C±5°C; the product has the following characteristics: the diameter of the particles is 6mm-8mm, the length is 1-5 times the diameter, and the moisture content is ≤16% .

[0022] The production method is as follows: using crop straw with low lignin content and calorific value and woody material with high lignin content and calorific value as raw materials, the crop straw and woody material are respectively crush...

Abstract

The invention relates to a biomass composite granular fuel, and a manufacturing method and device thereof. Crop straws with low lignin content and heat value and wood materials with high lignin content and heat value are used as the raw materials, pulverized, mixed in a random ratio and granulated to obtain the granular fuel. The manufacturing method comprises the following steps: using crop straws with low lignin content and heat value and wood materials with high lignin content as the raw materials, respectively pulverizing and drying the crop straws and wood materials, mixing, softening with steam, molding, cooling and packaging to make the granular fuel. The manufacturing device comprises a wood chipping and pulverizing system, a pulverized wood drying system, a straw cutting and pulverizing system, a pulverized straw drying system, a granulating system and a product processing and packaging system. The composite granular fuel of the invention does not need adhesive or other additives with high heat value, thereby keeping the fixed granule shape and enhancing the heat value of the fuel.

Description

technical field [0001] The invention relates to a biomass solid briquette fuel, in particular to a biomass composite particle fuel manufactured by utilizing crop straw and woody materials and a production method and equipment thereof. Background technique [0002] At present, with the emergence of the energy crisis worldwide and the increasingly serious environmental problems caused by the massive use of fossil fuels, countries all over the world pay more and more attention to the development and utilization of biomass energy. [0003] Biomass pellet fuel is a way of utilizing biomass energy. Its production raw materials are forestry "three leftovers" (wood processing residues, forest harvesting residues, and wood-making residues), various wood scraps, wood waste , crop straw (such as corn straw, sorghum straw, wheat straw, etc.), and shrubs (such as seabuckthorn), etc. The production process is to process the biomass raw material with loose texture and low energy density t...
