Heating and electricity production via domestic-scale pyrolysis of wastes to drive micro-gas turbines

“独特的家庭能源回收装置（HERU, www.myheru.com）于2021年6月在我们大学交付并投入使用。HERU允许家庭和企业从自己的废物中回收能源，将这些资源分解成可在热水锅炉中燃烧的可燃气体，从而节省资金并保护环境。同时，微型燃气轮机技术非常适合燃烧不同来源的燃气，并提供了将部分回收能源升级为更有价值的电力的机会，使这两种技术能够很好地匹配并产生协同效益。博士项目将包括三个主要领域：1。原料热解及热解产物分析。热解气体将由一系列具有代表性的原料产生，包括典型的家庭食物垃圾（面包、水果和蔬菜垃圾）、与这些食物相关的典型包装，以及来自餐饮和实验室的典型大学垃圾，包括咖啡杯和个人防护装备。热解气体的组成将根据原料和碳氢化合物、CO、CO2和H2的生产进行经验建模。该任务的交付成果将是一系列原料的气体生产和燃烧数据，并在一篇科学论文中提出，该论文还将HERU创新置于更广泛的能源背景下，并为这些原料和这种背景下的低温热解提供新的知识。MGT燃烧的气体成分包线在本任务中，将评估合成气含量对原料变化的敏感性，以了解涡轮机的运行包线。如果气体组分的可变性在一个狭窄的范围内，这将允许设计和使用一个紧密优化的燃烧系统；如果不能，则需要一个能容忍更大范围成分的系统。这项任务的成果将是一个适合燃烧HERU气体的MGT设计，并在一篇科学论文中提出，该论文还描述了集成系统。本任务将整合上述任务，以保持整个项目的一致性和完整性，并确保其实施是通过对各组成部分之间的相互作用和协同作用的清晰理解来实现的。这项任务的可交付成果将是一份提交给大学的报告，建议是否以及如何以支持教学和研究的方式将更大规模的单元整合到大学的能源系统中，以及一份详细评估的科学论文。”

"The unique Home Energy Recovery Unit (HERU, www.myheru.com) was delivered and commissioned at our university in June 2021. The HERU allows households and businesses to recover energy from their own wastes by pyrolysing these resources into combustible gases that can be burned in hot water boilers, saving money and saving the environment. Meanwhile, micro-gas turbine technology is well suited to burning gas of variable provenance and offers the opportunity to upgrade some of the recovered energy to more valuable electricity, making these two technologies well matched for synergistic benefits.The PhD project will encompass three main areas:1. Pyrolysis of feedstocks and analysis of pyrolysis products.Pyrolysis gases will be generated from a range of representative feedstocks including typical domestic food wastes (bread, fruit and vegetable wastes), typical packaging associated with these foods, and typical university wastes from catering and laboratories, including coffee cups and PPE.The constituent makeup of the pyrolysis gas will be modelled empirically in relation to feedstocks and production of hydrocarbons, CO, CO2 and H2. The deliverables from this task will be data on gas production and combustion from a range of feedstocks, presented in a scientific paper that also places the HERU innovation in the wider energy context, and contributing new knowledge about low temperature pyrolysis from these feedstocks and this context.2. Gas composition envelope for MGT combustionIn this task the sensitivity of the syngas content to feedstock variation will be evaluated, to understand the operating envelope of the turbine. If the variability of the gas components is within a narrow band, this will allow design and use of a tightly optimised combustion system; if not, a system tolerant to a wider range of constituents will be required. The deliverable from this task will be an MGT design suitable for combusting HERU gases, presented in a scientific paper that also describes the integrated system.3. LCA and techno-economic analyses within the university contextThis task will integrate the above tasks to maintain a coherence and integrity to the overall project and to ensure its implementation is informed by a clear understanding of the interactions and synergies between the components. The deliverables from this task will be a report to the university recommending whether and how to integrate larger-scale units into the university's energy systems in ways that also support teaching and research, and a scientific paper detailing the assessments."
