Combustion Characteristics of Diesel Blended with HTL in a Constant Volume Chamber 2019-01-0578

An estimated 20 million dry tons of volatile organic compounds, or biowaste, is annually deposited in US municipal wastewaters. Most of this biowaste energy content is not recovered and, as a result, the biowaste could be a massive potential source of renewable energy. Biocrude diesel is converted from wet biowaste via hydrothermal liquefaction (HTL). Three types of feedstocks (algae, swine manure, and food processing waste) were converted into biocrude oil via HTL. From the previous experiments done in an AVL 5402 single-cylinder diesel engine, it was observed that the presence of 10 to 20% of HTL in the blend perform similarly during combustion as pure diesel. By studying these mixtures in a constant volume chamber, these observations can be compared to the results in the diesel engine. Additionally, the constant volume chamber would give more insights as how the HTL actually affects the combustion characteristics. The experiments are conducted at different temperatures and atmospheric conditions.
