    摘要:

    選取我國糧食主產(chǎn)區(qū)的玉米秸稈及華北地區(qū)的7種農(nóng)作物秸稈為研究對象,采用生物質(zhì)原料測試方法、標(biāo)準(zhǔn)試驗研究了用于生產(chǎn)生物質(zhì)壓塊燃料的切碎物料(粒度為5~30mm)的理化特性。試驗結(jié)果表明,不同地區(qū)的玉米秸稈理化特性差異較大,東北地區(qū)的靜態(tài)堆積角最大,堆積密度最小,比其他地區(qū)平均低1725%,灰分含量最低;同一地區(qū)的不同農(nóng)作物秸稈的理化特性存在顯著差異,玉米秸稈和棉稈的動態(tài)外摩擦角顯著差異高于其他秸稈,豆秸、棉稈、花生殼的堆積密度最高。

    Abstract:

    The physical and chemical characterization of biomass crushed straw (practical size from 5mm to 30mm) which from major grain producing areas was studied and analyzed according to the biomass standards and methods introduced here. The results showed physical and chemical characterization of corn straw from different areas has significant difference. For northeast area, the static angle of repose was maximum, the ash was minimum and bulk density was 17.25%, lower than that of other area. The physical and chemical characterization of different straw from the same area has significant difference, too. The dynamic external friction angle of corn and cotton straw was much higher than that of other crop straw, for bulk density, the soybean, cotton and peanut straw was maximum. The model of net calorific value and proximate analysis was developed. The verification results showed that the largest regression coefficient P value was less than 0.05.
