竹粉贮存期对竹质机制炭性能的影响
Effect of Storage Period of Bamboo Powder on the Properties of Bamboo-based Charcoal
摘要
Abstract
Using bamboo powder as the raw material,samples were naturally piled up for 1,30 and 60 days,designated as D1,D30 and D60,respectively.After being extruded and formed,bamboo mechanical rods D1-B,D30-B and D60-B were obtained.Further carbonization was carried out to obtain bamboo mechanical charcoal D1-JT,D30-JT and D60-JT.The physical and chemical properties of the bamboo powder samples with different storage periods were analyzed,and the effects of storage period on the physicochemical properties,mechanical properties and combustion characteristics of the bamboo mechanical charcoal were investigated.The results showed that after the bamboo powder was naturally piled for 1 day(D1),30 days(D30),and 60 days(D60),the contents of cellulose,hemicellulose and lignin changed as well.The content of cellulose in D30(38.14％)increased,the crystallinity(58.12％)improved,and the lignin(total acid-soluble lignin and acid-insoluble lignin,31.93％)changed slightly,which was conducive to form a compact structure during the molding process.The bamboo-based mechanical charcoal D30-JT obtained from D30-B had the best resistance to crushing(97.70％),and the indicators such as fixed carbon(90.23％),volatile matter(6.01％)met the relevant standards requirements,and it also had excellent calorific value(low calorific value of 31 665 J/g).The peak value of heat release rate during the combustion process of D30-JT was 43.57 kW/m2,the total heat release amount was 61.82 MJ/m2,the average effective combustion heat was 35.23 MJ/kg,the combustion efficiency was high,the smoke production was low,and the combustion process was stable.Therefore,when the storage period of bamboo powder was 30 days,the quality and performance of the obtained bamboo-based mechanical charcoal were relatively high.关键词
