Optimising biomass milling, classification and conveying for enhanced power generation

该项目将探索生物质碾磨、分类和输送之间的基本联系，以优化生物质加工。该项目将探索碾磨断裂力学的基础科学，以开发通过压缩生物质颗粒粉碎的临界粒径测试。该测试将根据行业标准粘合工作指数铣削测试和实验室规模的立式主轴铣削进行基准测试。分类背后的基础科学将被调查，以确定生物量颗粒大小和形状对分类的影响，并与铣削断裂力学联系起来。将建立一个基于磨床磨出的产品来预测分级是否成功的模型。现有的检查管道中生物质输送的钻机将进一步开发，以分析广泛的生物质颗粒流动条件。一种新型的生物质颗粒绳系装置将被建立，以研究绳系及其与生物质颗粒大小和形状的联系。将制定绳索缓解策略，然后在实验室立式主轴磨机上进行气动分级验证。这将是一个为期四年的项目，总部设在诺丁汉大学的新弹性脱碳燃料能源系统CDT，并与净零研究合作伙伴合作。

This project will explore the fundamental link between biomass milling, classification and conveying to optimise biomass processing. The project will explore the fundamental science of milling fracture mechanics to develop a test for the critical particle size for comminution through compression for biomass particles. This test will be bench marked against the industry standard bond work index milling test and milling in a lab scale vertical spindle mill.The fundamental science behind classification will be investigated to ascertain the impact of biomass particle size and shape on classification and linked back to milling fracture mechanics. A model will be developed which can predict if classification will be successful based on the milled product from the grinding bed. An existing rig which examines biomass conveying in pipes will be further developed to analyse a wide range of biomass particle flow conditions.A novel biomass particle roping rig will be built to investigate roping and its link to biomass particle size and shape. Roping mitigation strategies will be developed, which will then be verified on a laboratory vertical spindle mill with pneumatic classification.This would be a four-year project based in the new Resilient Decarbonised Fuel Energy Systems CDT based at The University of Nottingham and working alongside Net Zero Research partners.
