项目摘要

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.

替代能源，如生物质，已被推荐作为化石燃料的替代品，以帮助环境和经济。Myera集团一直致力于开发一种综合生物质在加拿大北方地区，为可持续的供热和供电提供微型蒸汽涡轮机的颗粒炉。该项目建立在这样一个综合系统的已完成的可行性研究（NSERC Engage项目）的基础上。生物质的造粒改善了原料生物质的处理性能和能量特性，使其更可行的能源然而，来自农业残留物如稻草或燕麦壳的颗粒具有较低的生物相容性。热值，并且在处理和运输过程中容易分解，引起灰尘和问题。到有效地造粒这些材料，并增加生物质热能，添加高脂提出了以粗生物质为结合剂的四尾栅藻（Scenedesmus quadricade）。生物质源材料，如稻草和燕麦壳将被研磨，并将选择三种颗粒尺寸来生产小型的。不同粒度的源材料的不同比例和各种结合量例如Myera集团生产的藻类生物质。混合物将被压实，球团密度从800到1200 kg/m3不等。从能量角度优化颗粒污泥的生物质组成和耐久性的观点将被确定。在未来的计划中，该公司将进行实验，本项目的特点是采用颗粒燃料的热电联产系统。
