1337008AxebaumBiomass holds great potential as a fuel as it addresses two important issues ? global climate change and the demand for renewable fuels. Biomass generally has high moisture content and is usually dried before being utilized. Nonetheless, there are a number of applications where ?wet? biomass can be useful. For example, when biomass is burned with oxygen in a power plant and the resulting carbon dioxide is stored underground, the process leads to carbon negative power production. This program seeks to gain knowledge of the physico-chemical processes associated with combustion of high-moisture content fuels. Three types of biomass/water mixtures will be studied: alcohol/water solutions, algal suspensions, and biomass solubilized in water. The vaporization and combustion characteristics will be studied in single droplet experiments and in a spray combustor. Analytical models of two-component droplet vaporization and combustion will be used to understand and interpret results.This work will provide fundamental data needed to support technologies for a sustainable approach to power generation with carbon capture and storage. The research will be an important educational tool, exposing our youth to novel approaches to renewable, sustainable technologies. In addition, an innovative, interdisciplinary experiential course on Energy and Environment will be developed.

1337008axebaumbiomass在解决两个重要问题时具有巨大的燃料潜力？全球气候变化和对可再生燃料的需求。 生物质通常具有高水分含量，通常在使用之前干燥。 但是，有许多应用吗？生物质可能有用。 例如，当生物量在发电厂中用氧气燃烧并将二氧化碳储存在地下时，该过程会导致碳负发电。该计划旨在了解与燃烧高动物含量燃料相关的物理化学过程。 将研究三种类型的生物质/水混合物：酒精/水溶液，藻类悬浮液和在水中溶于水中的生物量。将在单滴实验和喷雾燃烧器中研究蒸发和燃烧特性。两组分液滴汽化和燃烧的分析模型将用于理解和解释结果。这项工作将为支持技术提供基本数据，以通过碳捕获和存储来支持可持续的发电方法。这项研究将是一种重要的教育工具，使我们的青年采取新颖的可再生能源技术方法。此外，还将开发有关能源和环境的创新，跨学科的体验课程。
