中文摘要:

      农业园区内生物质的集中处置具有便利性、经济性、规模灵活性等优势，生物质发电是农业园区能源系统的核心，但电力产能过剩或季节变化易导致资源浪费，引入生物质制炭产业可与生物质发电形成高效协同的产业模式。通过分析生物质热解制炭的研究进展及副产物处理的不足之处，提出将生物质燃烧发电、燃烧供热、生物质热解制炭耦合农业和能源系统，形成生物质能源的热电炭联产系统，实现园区内生物质燃烧发电供应电网、农业设施和用户，燃烧供热保证冬季低温时农业设施、温室大棚的取暖需求，热解制炭保证园区生物质生长及环境治理的需求，该系统有利于完善农业园区能源互联网的构建和实现“碳中和”的目标。

英文摘要:

      The centralized disposal of biomass in agricultural parks has advantages such as convenience, economy and flexibility of scale. Biomass power generation is the core of the energy systemin agricultural park, but excess power capacity or seasonal changes will lead to wasted resources. Based on the analysis of the research on biomass pyrolysis for biochar and the shortcomings of by-product treatment, it is proposed that biomass combustion for power generation, combustion for heat supply and biomass pyrolysis for biochar should be coupled with agriculture and energy system to form a biomass energy co-generation system. The biomass combustion for power generation can supply power for power grid, agricultural facilities and users. The biomass combustion for heat supply can ensure the heating demand of agricultural facilities and temperature greenhouses in winter. The biomass pyrolysis for biochar can ensure demands of the biomass growth and environmental governance in the agricultural parks. This system is conducive to improve the construction of energy Internet in agricultural parks and realize the aim of“carbon neutral”.
