介绍了一种用于清洁电炉灶燃烧界面的热声发动机的设计。SCORE项目进行的社会调查表明，在清洁炉灶上增加发电量应大大超过目前的8%水平（中国以外），因为电力被认为是高价值的，因此社区需要。这项工作讨论了开发过程中，使用BS 7000的正式设计方法的元素来设计一个大规模生产，易于制造，低成本的烹饪炉灶，使用热声发动机产生电力，同时烹饪。迭代的设计过程中进行了讨论，在每次迭代的预测成本和性能的分析，并与社会调查的目标集进行比较。根据目前可用的技术以及对模具和生产设施的适当投资，估计生产成本为100英镑。一家大型国际蓝筹公司的工程师和成本估算师进行的独立审计预测为150英镑。在设计的这个阶段，这被认为是相当好的相关性。有人建议将这项费用降低到60英镑。为了降低成本，需要进行更多的研究。SCORE市场评估表明，在60英镑（2007年价格）的上限成本目标下，6000万人将买得起炉子。基于所提出的平面热声发动机设计，烧木材的Score-Stove™2原型成功地开发了22.7 W的电力，这表明新的Score-Stove™2设计在批量生产时可能具有满足发展中国家农村人口的社会和烹饪需求的潜力。
A design of the thermo-acoustic engine to combustion interface of an electrically generating clean cookstove is presented. Social surveys carried out by the SCORE project have indicated that adding electrical generation to a clean cookstove should increase their uptake considerably above the current 8% level (outside China) as electricity is perceived as high value and so wanted by the communities. This work discusses the development process, using elements of the formal design methodology BS 7000 to design a mass-producible, easy-to-manufacture, low-cost cooking stove that uses a thermo-acoustic engine to produce electricity whilst cooking. The iterative design process is discussed with analyses made of predicted cost and performance at each iteration and compared with the targets set from social surveys. With currently available technology and suitable investment in tooling and production facilities, estimated production costs are £100. An independent audit by engineers and cost estimators from a large international blue chip company made a prediction of £150. At this stage of the design, this is considered a quite good correlation. Proposals for bringing this cost down to £60 are made. To obtain lower costs would require more research. SCORE market evaluations indicate that at the upper-cost target of £60 (2007 prices), 60 million people would afford the stove. A wood-burning Score-Stove™2 prototype successfully developed 22.7 W of electricity based on the presented planar thermo-acoustic engine design, indicating that the new Score-Stove™2 design may have the potential, when manufactured in volume, to meet the social and cooking requirements of rural people in developing countries.
