项目摘要

Experimental and numerical investigation of biomass combustion Decarbonisation of energy is, currently, a massive task before engineers and scientists. A large number of low carbon and zero carbon energy production methods are being investigated worldwide. Amongst these, bio-energy is one of the most promising ones. Living marine and land plants absorb solar energy and CO2 from the atmosphere/hydrosphere and turn them into energy containing materials, such as wood or agricultural waste, which are collectively called biomass. Unlike combustion of fossil fuels, burning of biomass does not result in increasing the carbon content of the atmosphere. Further, if combined with carbon capture technologies, it can lead to negative carbon emission. This aspect of combustion of biomass along with its widespread availability has made it an attractive energy resource for future. However, there exist significant technical difficulties in the deployment of biomass combustion at an industrial scale. Biomass has a complex and varying composition and the fundamentals of biomass combustion, compared to those of fossil fuels, are not well understood. This lack of understanding, currently, poses significant challenges to the design and operation of biomass burners. This doctoral research aims to obtain further understating of the fundamental physical and chemical processes involved in the combustion of biomass. These include heat and mass transfer, fluid dynamics, thermodynamics and chemical kinetics. The research will involve extensive numerical and theoretical studies as well as laboratory tests for validation purposes.

目前，生物质燃烧脱碳的实验和数值研究是摆在工程师和科学家面前的一项艰巨的任务。世界范围内正在研究大量的低碳和零碳能源生产方法。其中，生物能源是最有前景的能源之一。活的海洋和陆地植物从大气/水圈中吸收太阳能和二氧化碳，并将它们转化为含有木材或农业废物等材料的能量，这些材料统称为生物质。与燃烧化石燃料不同，燃烧生物质不会增加大气中的碳含量。此外，如果与碳捕获技术相结合，可能会导致负碳排放。生物质燃烧的这一方面及其广泛的可获得性使其成为一种有吸引力的未来能源。然而，在工业规模上部署生物质燃烧存在着重大的技术困难。生物质的组成复杂多样，与化石燃料相比，生物质燃烧的基本原理还没有得到很好的理解。目前，这种认识的缺乏给生物质燃烧器的设计和操作带来了巨大的挑战。这项博士研究的目的是进一步低估生物质燃烧所涉及的基本物理和化学过程。其中包括传热学、传质学、流体力学、热力学和化学动力学。这项研究将涉及广泛的数值和理论研究以及为验证目的而进行的实验室测试。
