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

2021年6月，独特的家庭能源回收装置(Heru，www.myheru.com)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，方法是将这些资源热解成可在热水锅炉中燃烧的可燃气体，从而节省资金和保护环境。同时，微型燃气轮机技术非常适合于燃烧来源不同的气体，并提供了机会将一些回收的能源升级为更有价值的电力，使这两种技术在协同效益方面非常匹配。PHD项目将包括三个主要领域：1.原料的热解和热解产品的分析。热解气体将从一系列具有代表性的原料中产生，包括典型的家庭食品垃圾(面包、水果和蔬菜垃圾)、与这些食品相关的典型包装、以及来自餐饮和实验室的典型大学垃圾，包括咖啡杯和PPE。热解气体的组成将根据原料和碳氢化合物、CO、PPE的生产进行经验模拟二氧化碳和氢气。这项任务的成果将是一系列原料的天然气生产和燃烧的数据，这些数据将在一篇科学论文中提出，该论文还将Heru的创新置于更广泛的能源背景下，并贡献了关于这些原料和本上下文的低温热解的新知识。MGT燃烧的气体组成包络在本任务中，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络。如果气体成分的变化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；如果不是，将需要一个能容忍更广泛成分的系统。这项任务的成果将是一种适用于燃烧Heru气体的MGT设计，该设计在一篇科学论文中提出，该论文也描述了集成系统。LCA和大学范围内的技术经济分析这项任务将整合上述任务，以保持整个项目的一致性和完整性，并确保通过清楚地了解各组成部分之间的相互作用和协同作用来实施项目。这项任务的成果将是向大学提交一份报告，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机组整合到大学的能源系统中，以及一份详细介绍评估的科学论文。

"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."
