Experimental and numerical investigation of biomass combustion Decarbonisation of energy.

生物质燃烧的实验和数值研究目前，能源脱碳是工程师和科学家面临的一项艰巨任务。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，生物能源是最有前途的能源之一。活的海洋和陆地植物从大气/水圈吸收太阳能和二氧化碳，并将它们转化为含能量的材料，如木材或农业废物，统称为生物质。与化石燃料的燃烧不同，生物质的燃烧不会导致大气中碳含量的增加。此外，如果与碳捕获技术相结合，它可以导致负碳排放。生物质燃烧的这一方面沿着其广泛可用性使其成为未来有吸引力的能源。然而，在工业规模上部署生物质燃烧存在显著的技术困难。生物质具有复杂和变化的组成，与化石燃料相比，生物质燃烧的基本原理尚未得到很好的理解。目前，这种缺乏了解对生物质燃烧器的设计和操作构成了重大挑战。这项博士研究旨在进一步了解生物质燃烧所涉及的基本物理和化学过程。这些包括传热和传质、流体动力学、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，以及验证目的的实验室测试。

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.
