生物质混配颗粒燃料的试验分析
Experimental Analysis of Biomass Pellets from Blended Feedstocks
摘要
Abstract
To promote the large-scale utilization of rice and corn straw in biomass pellet fuels,proxi-mate analysis,calorific value measurement,and thermogravimetric-derivative thermogravimetric(TG-DTG)analysis were employed to investigate the moisture,ash,volatile matter,fixed carbon,calorific value,and combustion characteristics of single-component pellets(rice straw,corn straw,and pine wood waste)and their blends.The results indicate that the calorific values of the blended pellets ranged between those of pure pine wood and pure straws,exhibiting moderate and balanced energy density.Specifically,rice straw pellets demonstrated the highest ignitability,while pine wood waste pellets exhibited the best overall combustion performance.Blends with higher pine wood content yiel-ded superior comprehensive combustion characteristics,whereas those with higher rice straw content showed better ignitability.Considering cost,calorific value,and combustion behavior,the optimal blending ratio was determined to be pine wood waste∶corn straw∶rice straw=6∶1∶3 in quality,achie-ving a net calorific value at received basis of 15.42 MJ/kg,a combustibility index(C)of 47.91 × 10-5％·min-1·℃-2,and a comprehensive combustion characteristic index(S)of 181.16 × 1 0-7％2·min-2·℃-3.关键词
