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.

1337008Axebaum生物质作为燃料具有巨大的潜力，因为它解决了两个重要问题？全球气候变化和对可再生燃料的需求。生物质通常水分含量高，通常在利用前干燥。尽管如此，还是有很多应用场合？湿的？生物质能是有用的。例如，当生物质在发电厂中与氧气一起燃烧时，产生的二氧化碳被储存在地下，这个过程会导致碳负电力生产。本课程致力于获得与高水分燃料燃烧相关的物理化学过程的知识。将研究三种类型的生物质/水混合物：酒精/水溶液、藻类悬浮液和溶解在水中的生物质。汽化和燃烧特性将在单液滴实验和喷雾燃烧室中进行研究。将使用双组分液滴蒸发和燃烧的分析模型来理解和解释结果。这项工作将提供支持碳捕获和储存发电的可持续方法所需的基本数据。这项研究将是一个重要的教育工具，让我们的年轻人接触到可再生、可持续技术的新方法。此外，还将开发一门创新的、跨学科的能源与环境体验课程。
