Biomass pellet fuel and preparation method thereof

Abstract

The invention provides a biomass pellet fuel and a preparation method thereof. The biomass pellet fuel comprises the following components, by weight: herbivorous animal manure, agricultural waste, illegal cooking oil, calcium oxide, calcium sulfate, propionic acid, kaolin, diatomaceous earth, bentonite, calcium peroxide, aluminum hydroxide, propylene glycol, polyvinyl alcohol, an oxygenate, an antiknock agent, a combustion improver, and a bulking agent. The biomass pellet fuel has low water content and high lignin content. According to the invention, a large amount of agricultural waste and animal manure are utilized. Air pollution caused by the activities of burning agricultural waste is greatly reduced, and animal manure can be effectively treated, such that recycling application value is improved, and the fuel is more environment-friendly. Compared to conventional biomass pellet fuels, the biomass pellet fuel provided by the invention has the advantages of high combustion value, long combustion time, no harmful gas emission after combustion, and no corrosion to combustion equipment.

Description

technical field

[0001] The invention relates to a biomass particle fuel and a preparation method thereof. Background technique

[0002] Biomass pellet fuel is a fuel made by compressing biomass raw materials (mainly crop stalks, agricultural product processing residues and forestry residues) after drying, crushing, blending and other pretreatments. The granular fuel density after molding is greater than 1000kg / m 3 , the combustion value is 3500~5000kcal / kg, the energy density is equivalent to that of medium bituminous coal, and it is convenient to transport and store. It can replace coal and other fossil fuels in civil fields such as cooking and heating, and industrial fields such as boiler combustion and power generation.

[0003] Biomass pellet fuel is mostly block-packed environmentally friendly new energy produced by processing stem-shaped crops. Its diameter is generally 6-8 cm, and its length is 4-5 times its diameter. The breakage rate is less than 1.5-2.0%. Less th...
