Assessment of the aerodynamic behaviour of fibrous particles under well-defined conditions of relevance to bio-fuel combustion

生物质是植物源燃料，具有温室中性的优势。在对现有燃烧技术稍加修改后，生物质可以潜在地用于专门设计的燃烧器。它通常作为碎颗粒（例如木材、稻草或甘蔗渣）与空气一起被送入炉子或锅炉，可以单独使用，也可以部分替代煤粉。然而，这些颗粒是纤维状的，与圆形颗粒不同，它们在这种系统中的空气动力学行为尚不清楚。该项目将提供新的理解、数据和模型，以最大限度地提高这些燃料的使用效率和减少排放。

Biomass is plant-derived fuel, which has the advantage of being greenhouse neutral. Biomass can potentially be utilised both in existing combustion technologies, after minor modifications, and in purpose-designed combustors. It is typically fed into a furnace or boiler as shredded particles, (e.g. of wood, straw or bagasse), with jet(s) of air, either alone or as partial replacement of pulverised coal. However these particles are fibrous and, unlike round particles, their aerodynamic behaviour in such systems is poorly understood. The project will provide new understanding, data and models necessary to maximise efficiency and minimise emissions from the utilisation of these fuels.
