Thermal energy of pellets from biomass supplemented with microalgae

生物质等替代能源已被推荐作为化石燃料的替代品，以帮助 环境和经济。迈拉集团一直致力于开发一种综合生物质 为加拿大北部地区提供可持续供热和电力供应的微型蒸汽轮机球团炉灶。 该项目建立在这样一个综合系统的已完成可行性研究(NSERC Engage项目)的基础上。 生物质的造粒改善了生物质的操纵性和能量特性，使其 一种更可行的能源。然而，从秸秆或燕麦壳等农业残渣中提取的颗粒含量较低。 它具有很高的热值，很容易分解，在搬运和运输过程中会产生粉尘和问题。至 有效造粒这些材料，增加生物质热能，添加高脂 提出了以海藻(栅藻)为粘结剂的生物质粘结剂。生物质来源 稻草和燕麦壳等材料将被研磨，并将选择三种颗粒大小来生产 紧凑型的。不同颗粒大小和不同粘结量的来源材料的不同比例 将对Myera Group生产的藻类生物质等制剂进行调查。混合物将被压实成 各种级别的颗粒密度从800公斤/立方米到1200公斤/立方米不等。从能源角度优化球团矿生物质组成 并将确定耐久性的观点。在未来的计划中，该公司将进行试验 本项目以球团热电联产系统为特色。

Alternative energy sources, such as biomass, have been recommended as substitutes for fossil fuels to help the environment and the economy. Myera Group has been working on developing an integrated biomass pellet-stove with a micro steam-turbine for a sustainable heat and power supply in northern Canadian regions. This project builds on the completed feasibility study (NSERC Engage project) of such an integrated system. Pelletization of biomass improves the handling properties and energy characteristics of raw biomass, making it a more viable energy source. However, pellets from agricultural residues such as straw or oat hulls have lower calorific value and can easily disintegrate causing dust and problems during handling and transportation. To effectively pelletize these materials and to increase the biomass thermal energy, an addition of high lipid content algae (Scenedesmus quadricaude) to raw biomass as the binding agent is proposed. The biomass source material such as straw and oat hulls will be ground and three particle sizes will be selected to produce compacts. Different ratios of source material of a different particle size and various quantities of the binding agent such as algae biomass produced by Myera Group will be investigated. The mixture will be compacted to various levels of pellet density from 800 to 1200 kg/m3. Optimal pellet's biomass composition from the energy and durability point of view will be determined. In the future plans, the company will conduct experiment with the combined heat and power system using pellets characterized in this project.
