项目摘要

The broader impact/commercial potential of this I-Corps project is the development of an energy recovery system capable of converting waste heat energy in the form of excess vapor or exhaust gas into usable electricity using the physics of acoustic waves. Documented efficiencies of these systems are approximately 20%. The target end user of would be a large-scale industrial facility in the food and beverage, automotive, heavy metal, or oil and natural gas industries or a rural government entity struggling with waste heat management and/or committed to providing power to off-grid areas. The proposed technology is driven by low grade waste heat in the form of vapor or exhaust from various processes. For example, there has been a recent increase in the number of manufacturing sites utilizing combined heat and power (CHP) units that output low grade steam at a high mass flow rate. This technology would act as a complementary system to CHP, providing further cost-savings by supplying electric power from harnessed low-grade steam energy. By integrating the proposed technology into a manufacturing facility, thermal pollution caused by high temperature vapor output will be mitigated by cooling the vapor before releasing it into the environment.This I-Corps project is based on the development of an energy recovery system comprised of two independent subsystems: (1) a thermal module to harness the waste heat from a vapor stack or exhaust gas tubing; and (2) a thermoacoustic electric generator to convert the waste heat into electric power. Each thermal module may be custom-made for any industry partner depending on the size and thermal capacity of the vapor stack available. The heat energy harnessed in the thermal module will be transferred via a heat transfer fluid into the thermoacoustic electric generator. The thermoacoustic electric generator will remain consistent across all systems allowing for more streamlined manufacturing. The proposed innovation may be scaled similarly to the size of a small backup generator seen in private homes or scaled to the size of a natural gas generator used in heavy industry. Industrial sponsors have aided the advance of the technology using multiple types of working fluids and energy extraction methods. In addition, there has been substantial advancement in computational modeling used to predict the physics of the fluid phenomenon that is responsible for the heat energy conversion, focusing specifically on traveling waves.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
I-Corps项目的更广泛影响/商业潜力是开发一种能量回收系统,能够利用声波物理学将多余蒸汽或废气形式的废热能转化为可用电力。这些系统的记录效率约为20%。的目标最终用户将是食品和饮料,汽车,重金属或石油和天然气行业的大型工业设施,或努力进行废热管理和/或致力于为离网地区提供电力的农村政府实体。所提出的技术由来自各种过程的蒸汽或废气形式的低级废热驱动。例如,近来利用以高质量流率输出低等级蒸汽的热电联产(CHP)单元的制造场所的数量有所增加。这项技术将作为热电联产的补充系统,通过利用低品位蒸汽能源提供电力来进一步节省成本。通过将所提出的技术集成到制造设施中,将通过在将蒸汽释放到环境中之前冷却蒸汽来减轻高温蒸汽输出所引起的热污染。I-Corps项目基于开发由两个独立子系统组成的能量回收系统:(1)热模块,用于利用来自蒸汽烟囱或废气管道的废热;以及(2)将废热转换成电能的热声发电机。每个热模块可以根据可用蒸汽堆的尺寸和热容量为任何行业合作伙伴定制。在热模块中利用的热能将经由传热流体传递到热声发电机中。热声发电机将在所有系统中保持一致,从而实现更精简的制造。所提出的创新可以类似于私人家庭中看到的小型备用发电机的大小或缩放到重工业中使用的天然气发电机的大小。工业赞助商使用多种类型的工作流体和能量提取方法来帮助技术的进步。此外,在预测热能转换的流体物理现象的计算建模方面也取得了实质性进展,特别是在行波方面。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
