Low grade heat utilisation obtain

项目摘要

Technical background: The PhD studentship will investigate possible utilisation of low-grade heat sources, for example surplus low grade heat from the new automotive paint shop of NISSAN UK being designed by GEICO TAIKISHA and which will be opened in March 2017. The objective of the research is to introduce a framework to ease the environmental characterization and improvement in end use energy demand. Energy efficiency has quickly become a top priority because of the high energy use in industrial operations, which are responsible for significant CO2 emissions and thus, climatic changes. An automotive manufacturing plant has very large energy use and the painting shop example is particularly major responsible for this. The application of the framework will identify opportunities for improving energy use in order to achieve a reduction in operating costs and greenhouse gas emissions. In industry, a significant amount of energy is commonly used by equipment such as pumps, compressors, boilers, prime movers, ovens, chillers, dryers, process heaters, process coolers, ventilation equipment, etc. Thermal energy loss in each operation cannot be avoided and therefore manufacturing industry, characterised by a large number of operation units, has an inevitable large source of thermal energy loss. Hence, with higher energy cost and the increased importance of rationalising energy use, thermal energy management is likely to become an increasingly fundamental issue in the future. Decreasing the amount of end-use energy demand would help NISSAN to achieve sustainable processes with subsequent important results in terms of cost competitiveness and making progress toward environmental goals. This can be achieved by recovering low-grade heat (T<260 C), which if not captured and used, is mostly released into the atmosphere, thus giving rise to energy and resource losses and missing an energy efficiency opportunity. Innovative technologies will be assessed for their ability to recovery this energy and the scope of their utilisation. Project summary: In order to identify and estimate all the possible low-grade heat sources and to utilise them, it is firstly required to evaluate how much heat can be theoretically recovered from the industrial processes. This evaluation will be done through a pinch and exergy analysis. Pinch analysis is a methodology for minimising the energy consumption of processes by calculating thermodynamically feasible energy targets and achieving them by optimising heat recovery systems, energy supply methods and process operating conditions. At the same time, exergy analysis results to aid in determining the potential usefulness of a given low-grade heat source and determine the maximum amount of mechanical work which can be obtained. After the characterisation of available low grade heat sources, the most appropriate innovative technical solution for recovery and utilisation will be evaluated in order to assess the potential end use energy reduction obtained. An economic analysis of the solutions will be conducted to explore the impact on capital and operational costs to determine payback periods and commercial viability. Project outcomes: Detail techno-economic reports analysing innovative solutions to utilise low grade heat sources to reduce manufacturing energy demand. It is expected that at least 4 high impact publications in leading journals such as Applied Energy and Applied Thermal Engineering. In addition, 3 presentations at world leading conferences such as Sustainable Energy Technology, and Heat Powered Cycles.

技术背？由于工业运营中的高能源使用，能源效率已迅速成为重中之重，这些二氧化碳的排放量很大，因此导致了气候变化。汽车制造工厂的能源使用非常大，绘画店的例子特别是主要负责。该框架的应用将确定改善能源使用的机会，以减少运营成本和温室气体排放。在行业中，大量能源通常由泵，压缩机，锅炉，原动搬运工，烤箱，冷水机，干衣机，工艺加热器，工艺冷却器，通风设备等设备进行。每个操作中的热能损失均无法避免，因此无法避免制造业，因此以大量的操作单元来表征，具有大量的热能损失。因此，随着能源使用较高的能源使用的重要性，热能管理可能会成为将来越来越基本的问题。减少最终用途能源需求的数量将有助于日产在成本竞争力和朝着环境目标取得进步方面的重要成果，实现可持续过程。这可以通过恢复低级热量（t <260 c）（如果未捕获和使用）来实现，从而大多将其释放到大气中，从而导致能源和资源损失并缺少能源效率的机会。将评估创新技术的能力，以恢复这种能量及其利用范围。项目摘要：为了识别和估计所有可能的低级热源并利用它们，首先需要评估从工业过程中可以从理论上回收多少热量。该评估将通过捏和热分析进行。捏合分析是一种通过计算热力学可行的能量目标来最大程度地降低过程能源消耗的方法，并通过优化热恢复系统，能源供应方法和过程工作条件来实现它们。同时，释放分析结果有助于确定给定低度热源的潜在有用性，并确定可以获得的最大机械工作量。在表征可用的低级热源后，将评估最合适的恢复和利用创新技术解决方案，以评估所获得的潜在终端用途减少能量。将对解决方案进行经济分析，以探索对资本和运营成本的影响，以确定投资回报期和商业可行性。项目成果：细节技术经济报告分析创新解决方案以利用低级热源来减少制造能源需求。预计在领先的期刊（例如应用能源和应用热工程）中，至少有4个高影响力出版物。此外，在世界领先的会议上的3个演讲，例如可持续能源技术和热量循环。
