项目摘要

World-wide, energy conversion is currently dominated by the combustion of fossil fuels. Electricity generation and transport are key energy consumers and contribute significantly to atmospheric CO2, NOx, and particulate emission. There is an increasing awareness in the public eye of the potential impact of particulates on health. This includes a higher risk of cancer, asthma and a potential contribution to neurodegenerative disorders (e.g., Alzheimer's disease). In the UK, particulate matter (PM) from combustion processes is a significant contributor to poor air quality in urban areas; it has been reported that more than 25,000 deaths per year could be attributed to long-term exposure to anthropogenic particulate air pollution. As reported by DEFRA, poor air quality is the largest environmental risk to public health in the UK, contributing to an estimated £2.7 billion per year in lost productivity. Air pollution also results in damage to the natural environment, contributing to the acidification of soil and watercourses. An obvious solution might be to move towards the replacement of vehicles with electric, however, this technology is limited by range, recharge times and the cost of the battery - for which there is currently not the sufficient global infrastructure to directly replace vehicles powered by internal combustion engine powered. Another complementary solution is to find alternative fuels that are tailored to reduce destructive emissions such as NOx and particulates. This has the advantage that it could be rapidly deployed due to the overlap with existing fuel station infrastructure.The main aim of the proposed research is to provide a fundamental understanding of the combustion performance and emissions characteristics of key biofuels. This is vital knowledge to aid the development of next-generation low carbon technologies. The key objectives are: (1) to provide high-quality experimental data from a study of spray flame behaviour and emissions using advanced optical diagnostic techniques such as laser-induced breakdown spectroscopy and laser-induced fluorescence, (2) to develop new combustion chemical kinetic models, based on COSILAB (Combustion Simulation Laboratory software), predicting soot and NOx emissions and (3) to establish collaborations with industrial and academic partners to investigate power generation and transport applications for next-generation biofuels. In the proposed research, the targeted biofuels are: (1) ethanol, (2) iso-pentanol, (3) dimethyl ether (DME) and (4) combined fuels - ethanol, iso-pentanol, DME and biomethane. These key fuels are potentially next-generation biofuels. The production paths of these fuels are either well established or achievable. Ethanol and DME have already shown evidence of reduced emissions from engine tests. The understanding of combustion chemistry is essential to enable the delivery of a low NOx and soot emission combustion system. How the local chemistry is influenced by various turbulent flow conditions will be examined in detail.

全球范围内的能源转化目前由化石燃料的组合主导。发电和运输是关键的能源消费者，并为大气中的二氧化碳，NOX和特定的排放做出了重大贡献。公众对特殊性对健康的潜在影响的认识越来越高。这包括癌症，哮喘的较高风险以及对神经退行性疾病（例如阿尔茨海默氏病）的潜在贡献。在英国，组合过程中的颗粒物（PM）是城市地区空气质量差的重要贡献。据报道，每年超过25,000人死亡可能归因于人为特定空气污染的长期暴露。正如Defra报道的那样，较差的空气质量是英国公共卫生最大的环境风险，估计每年的生产力损失损失27亿英镑。空气污染还会导致自然环境损害，导致土壤和水道的酸化。一个明显的解决方案可能是朝着用电动替换车辆的车辆迈进，但是，该技术受范围，充电时间和电池成本的限制 - 目前，目前没有足够的全球基础设施直接替换由内部组合发动机供电的车辆。另一个完整的解决方案是找到量身定制的替代燃料，以减少NOX和组件等破坏性排放。由于与现有的加油站基础设施重叠，因此可以快速部署它的优势。拟议研究的主要目的是提供对关键生物燃料的组合性能和排放特征的基本理解。这是有助于发展下一代低碳技术的重要知识。关键对象是：（1）使用先进的光学诊断技术提供高质量的实验数据，并使用先进的光学诊断技术（例如激光引起的分解光谱镜头和激光诱导的荧光）（2）开发新组合化学动力学模型，基于cosilab（燃烧工业）和（EMISSIONS），EMISSORS和NOTISS（EMSISS），EMSISS和NOTISS（2）学术合作伙伴调查下一代生物燃料的发电和运输应用程序。在拟议的研究中，靶向的生物燃料为：（1）乙醇，（2）异戊醇，（3）二甲基醚（DME）和（4）组合燃料 - 乙醇，异戊醇，DME，DME和生物甲烷。这些关键燃料可能是下一代生物燃料。这些燃料的生产路径要么已经建立或实现。乙醇和DME已经显示出发动机测试排放减少的证据。对组合化学的理解对于能够提供低NOx和烟灰发射组合系统至关重要。将如何详细研究局部化学如何受到各种湍流条件的影响。
