青岛市秸秆资源潜力及利用现状

Potential and utilization of straw resources in Qingdao

通过年鉴对青岛市近5年来小麦、玉米、棉花和花生等作物的产量统计数据分析,结合不同作物草谷比的计算方法,得出对应秸秆总量,从中发现青岛市近年来秸秆总产量发展平稳,能源回收利用潜力巨大。采用秸秆直接燃烧或者气化的方法进行热电联产,不仅能够达到节能减排的目的,还能实现可观的经济效益。十三五期间,应结合秸秆热值采取不同技术手段,加强对生物质资源开发与利用。

The statistical data in recent five years in Qingdao city of wheat, corn and cotton and peanut and other crops were analyzed and the corresponding total amount of straw was obtained in the way of combining with the calculation method of different crops of grass valley ratio. And as a result, it was found that in recent years, the total output of straw in Qingdao was stable, and the potential of energy recovery and utilization was huge. It can not only achieve the purpose of energy saving and emission reduction, but also achieve considerable economic benefits by using the method of direct combustion or gasification of straw. During the 13th Five-Year period, using different means combined with the calorific value of straw can strenathen the development and utilization of biomass resources.
