陕西省秸秆资源能源化潜力评价

农作物秸秆是一种重要的生物质能源。由于滞后的思维方式、传统的观念以及技术落后等问题而造成大量的农作物秸秆仍无法取得高效的利用,陕西省的农作物秸秆资源利用率仅不到30%,剩下的70%多仍为废弃、焚烧等方式粗犷利用,导致环境污染严重、能源大量流失。通过对陕西省2011年的农作物秸秆产量进行分析,利用统计数据,计算出可利用的秸秆资源量,并将可利用秸秆资源量转化成标准煤量,为陕西省秸秆资源利用提供基础数据及决策参考,得出假设:将所有的可收集利用秸秆资源完全用作能源使用,计算得2011年陕西省农作物秸秆可收集利用资源量1 196.82万t,折合标准煤663.56万t,约占当年陕西省总能源消耗的6.55%。

Energy Potentiality of Crop Straw Resources in Shaanxi Province

Crop straw is an important biomass energy.Because of the lagged mode of thinking,traditional view and lag in technology,ect.,a mass of crop straw still cannot get efficient use,the use ratio of crop straw in Shaanxi Province was merely 30%,the 70% left was still abandon,burn or other inefficiency way to use,which resulted in the serious environmental pollution,and large abundant energy wast.This article analyzed the yield of crop straw in Shaanxi Province in 2011,used the statistical data,figured out the amount of available crop straw,and transformed the available crop straw into standard coal,and provided the basic data and decision reference for the use of crop straw in Shaanxi Province.Obtain was that if all of the collectable crop straws would be use of energy,calculated that the amount of collectable and available crop straw in Shaanxi Province in 2011 was 1 196.82 ×104 Ton,converted into 663.56×104Ton standard coal,about 6.55 % of the whole energy cost in Shaanxi Province in the year.
