Macadamia nut peel and shell-based high-strength high-combustibility biomass pellet fuel and preparation method thereof

The invention relates to the technical field of biomass pellet fuel and agricultural waste resource utilization, in particular to macadamia nut peel and shell-based high-strength and high-combustibility biomass pellet fuel and a preparation method thereof. The biomass pellet fuel comprises peels and shells of macadamia nuts, a combustion improver, a sulfur-fixing agent and a cementing agent, the particle sizes of peels and shells of the macadamia nuts are less than 1mm; the peels and shells of the macadamia nuts are mixed according to the mass ratio of (2: 1)-(2: 2). The invention provides the high-calorific-value and high-combustibility biological granular fuel which is stable in mechanical property, good in anti-corrosion property and high in calorific value. 本发明涉及生物质颗粒燃料和农业废弃物资源化利用技术领域，尤其涉及一种澳洲坚果果皮和果壳基高强度高燃烧性生物质颗粒燃料及制备方法。本发明所述生物质颗粒燃料，包括澳洲坚果的果皮以及果壳、助燃剂、固硫剂和胶结剂；所述澳洲坚果的果皮以及果壳的粒径在1mm以下；澳洲坚果的果皮和果壳按照2:1～2:2的质量比进行混合。本发明提供了一种机械性能稳定、防腐性能好的高热值、高燃烧性生物颗粒燃料。
