Globally, 3 billion people have no access to clean cooking, relying instead on dirty-burning charcoal as primary cooking and water heating fuel. The release of CO and PM (linked to \>4M deaths/year) led the WHO to declare pollution caused by unclean cooking as "the world's largest single environmental health risk". As its alternative, the use of firewood substantially influences deforestation, due to unregulated foraging for firewood, while negatively impacting wildlife.Quality of life in Sub-Saharan Africa is also severely impacted by lack of (domestic and institutional) access to electricity. According to the WDI, 72% of Zambia's population has no access to electricity.The SPITFIRE-stove will address both the major unmet need for clean cooking solutions and the lack of access to electricity. This will be achieved by developing an affordable, low-emission, biomass-pellet-burning clean-cookstove that generates a no-added-fuel electricity surplus. The institutional SPITFIRE-stove will use temperature-controlled airflow regulation to ensure complete combustion to eliminate \>80% of CO and particulate-matter emissions compared to traditional combustion. Airflow regulation will be via an electric fan, powered by a thermoelectric generator (TEG), which will both power the electric fan and provide an electricity surplus for storage in a low-voltage battery with charge-out ports for charging/powering small electronic devices. Furthermore, cooling of the TEG by an integrated water-cooling system will deliver a free supply of heated water.SPITFIRE will develop:-Novel high-temperature thermoelectric materials and production processes for the TEGs,-15kW burner technology that allows intelligent, temperature-controlled airflow regulation;-Institutional-scale, sustainable biomass-pellet-burning stove.Integration of the scaled-up stove and burner design with the novel high-temperature TEG module via hot- and cold-side heat receptors/exchangers will require close collaboration between the partners and multiple iterations of system level modelling and simulation. The SPITFIRE project ultimately aims to deliver a final stove design, assemble 30 demonstrator products, and validate stove performance in field trials within institutional kitchens in public services and local enterprises such as restaurants, schools, and orphanages, in our primary target market, Zambia.The SPITFIRE-stove will therefore address the clean cooking and energy dilemma by;-Delivering clean, sustainable biomass-burning cooking stoves with low emissions,-Delivering cooking stoves that will utilise reduced-cost biomass pellet fuels that are approximately one-third of the price of LPG and half of the price of charcoal, Ensuring reliability of energy supply for Zambia and beyond by utilising locally-sourced sustainable forestry for the biomass pellets.

全球有 30 亿人无法获得清洁烹饪，而是依靠燃烧肮脏的木炭作为主要烹饪和热水燃料。 CO 和 PM 的释放（与每年超过 400 万人的死亡有关）导致世界卫生组织宣布不清洁烹饪造成的污染是“世界上最大的单一环境健康风险”。作为替代方案，由于对木柴的采集不受管制，使用木柴会严重影响森林砍伐，同时对野生动物产生负面影响。撒哈拉以南非洲地区的生活质量也因缺乏（国内和机构）电力供应而受到严重影响。根据 WDI 的数据，赞比亚 72% 的人口无法用上电。SPITFIRE 炉灶将解决清洁烹饪解决方案未满足的主要需求和缺乏电力的问题。这将通过开发一种经济实惠、低排放、生物质颗粒燃烧的清洁炉灶来实现，该炉灶可产生不添加燃料的电力盈余。机构级喷火炉将采用温控气流调节来确保完全燃烧，与传统燃烧相比，可减少 80% 以上的二氧化碳和颗粒物排放。气流调节将通过由热电发电机 (TEG) 供电的电风扇进行，TEG 既可以为电风扇提供动力，又可以提供剩余电力以存储在带有充电端口的低压电池中，以便为小型电子设备充电/供电。此外，通过集成水冷系统对 TEG 进行冷却将免费供应热水。SPITFIRE 将开发：-用于 TEG 的新型高温热电材料和生产工艺，-15kW 燃烧器技术，可实现智能、温度-受控气流调节；-机构规模、可持续生物质颗粒燃烧炉。通过热侧和冷侧加热，将放大炉和燃烧器设计与新型高温 TEG 模块相集成受体/交换器将需要合作伙伴之间的密切合作以及系统级建模和仿真的多次迭代。 SPITFIRE 项目的最终目标是在我们的主要目标市场赞比亚，提供最终的炉灶设计，组装 30 个演示产品，并在公共服务机构和当地企业（如餐馆、学校和孤儿院）的机构厨房的现场试验中验证炉灶性能。因此，喷火炉将通过以下方式解决清洁烹饪和能源困境：-提供清洁、可持续、低排放的生物质燃烧炉灶，-提供采用低成本的炉灶生物质颗粒燃料的价格约为液化石油气价格的三分之一，木炭价格的一半，通过利用当地来源的可持续林业生产生物质颗粒，确保赞比亚及其他地区能源供应的可靠性。
