摘要
AnnotationPurpose。在以能源为目的的收获玉米和向日葵副产品的技术过程中,将能源成本系统化。在数理统计基本规定的基础上处理分析和实验数据,利用计算机和数学仿真软件环境MathCad, statistics, Microsoft Office.Results。给出了玉米和向日葵能源利用效率指标的计算方法。得出了不同湿度条件下玉米和向日葵压榨碎体收获工艺过程的能量效率与作物非籽粒部分产量的关系。结果表明,补偿作物非谷物部分不同成分所去除元素的能量成本值差异显著:玉米- 0.36-2.15 MJ/kg;向日葵- 0.7-1.63 MJ/kg。考虑到养分去除,所开发的以能源为目的的玉米收获过程的能源效率系数为10.5-11.5,向日葵为8.7-9.0,湿度为20%。关键词:玉米、向日葵非粒部分收获,非粒部分收获,能效。
Research on energy efficiency of the process of harvesting by-products of corn and sunflower
Annotation
Purpose. Systematize energy costs in the implementation of technological processes for harvesting by-products of corn and sunflower for energy purposes.
Methods. Processing of analytical and experimental data based on the basic provisions of mathematical statistics, simulation using a computer and software mathematical environments MathCad, Statistics, Microsoft Office.
Results. The calculations of energy efficiency indicators of the use of corn and sunflower for energy purposes are given. The dependences of the energy efficiency of the technological process of harvesting the crushed mass of corn and sunflower in pressed form on the yield at different levels of humidity of the non-grain part of the crop are obtained.
Conclusions. It is established that the value of energy costs to compensate for the removal of elements by different components of the non-grain part of the crop varies significantly: corn – 0.36–2.15 MJ/kg; sunflower – 0.7–1.63 MJ/kg.
The coefficient of energy efficiency of the developed process of harvesting corn for energy purposes, taking into account the removal of nutrients is 10.5–11.5, sunflower – 8.7–9.0, with a humidity of 20%.
Keywords: non-grain part of corn and sunflower harvest, harvesting of non-grain part, energy efficiency.
