谷子秸秆固体燃料热压缩工艺研究
Study on the thermal compression process of briquette produced from millet straw
摘要
Abstract
[Objective] This study was proposed to provide reference and evidence for the design of millet straw compress equipment .[Methods] The study investigated the effects of the moisture content ,temperature ,applied pressure ,and particle size of millet straw on the density ,durability ,and impact resistance of briquette by using single factor test de-sign One-Way ANOVA .The optimal conditions for preparing the solid briquette with millet straw were determined u-sing the Taguchi method .[Results]The results showed that the necessary moisture content was ranged from 6％ ～10％ for producing briquettes with good-quality ,and process temperatures was between 70 ～ 100 ℃ with pressures at 70 ～ 110 MPa and particle size smaller than 0.63 mm .The best parameter combination was as follow :particle size at 0.16 ～ 0.63 mm ,moisture at 8％ (w .b .) ,temperature at 90 ℃ ,and pressure at 110 MPa .The confirmation experi-ment was carried out according to the optimal conditions and the density of briquette reached up to 1.26 g·cm - 3 ,the maximum value .Moreover ,the contribution of each factor to the final briquette quality was particle size at 61.4％ , moisture content at 11.2％ ,pressure at 9.1％ ,and temperature at 8.1％ ,therefore ,the size of the smashed millet straw played a crucial role to solidify fuel briquette .[Conclusion]The results confirmed the feasibility of millet straw as energy raw material ,and provided reference for the design of processing equipment for millet straw solid biofuel .关键词
