Sauce (“Wot”) preparation and Injera baking using an open-fire stove are recurrent cooking activities in rural households in Ethiopia. The low thermal efficiency open-fire stove utilized huge quantities of fuel and caused high particulate matter exposure for cookers. A rocket stove is proposed and fabricated that burns commonly used biomass fuel. The Aprovecho Research Center design guiding principles were followed to develop the prototype. The overall performance of the model was tested using a water boiling test (WBT version 4.2.3) to confirm thermal efficiency improvement and air pollutant reduction compared to the conventional stove. Indoor air pollution (IAP) measuring apparatus was installed to record the carbon monoxide (CO) and fine particulate matter (PM_2.5) emission exposure of the cooker during the WBT test. The performance testing result of the model has shown an improved thermal efficiency of 32% compared to the three-stone stove (14%). The stove reduced CO concentration by 42% and PM_2.5 concentration by 99.5% over the three-stone stove. The average concentration exposure for an hour (3.1 μg/m³ CO) of the new stove satisfies the World Health Organization indoor air quality standard. Furthermore, the stove showed a 43% reduction in specific fuel consumption (roughly 625 kg fuel saving/year/device). The fuel-saving achieved from the model resulted in the reduction of CO₂ gas emissions by 1.3 tCO₂/year. Therefore, it is assumed that the rocket stove has a considerable improvement over the open-fire stove and its timely development may enhance environmental care. Therefore, shifting the cooking technology from the conventional traditional cooking stove to rocket stoves could mitigate indoor air pollutant emissions and deforestation.

使用明火炉准备酱料（“Wot”）和 Injera 烘焙是埃塞俄比亚农村家庭经常进行的烹饪活动。低热效率的明火炉使用了大量的燃料，并导致炊具的颗粒物暴露量很高。提出并制造了一种燃烧常用生物质燃料的火箭炉。遵循 Aprovecho 研究中心的设计指导原则来开发原型。使用水沸腾测试（WBT 版本 4.2.3）对模型的整体性能进行了测试，以确认与传统炉相比，热效率提高和空气污染物减少。安装室内空气污染 (IAP) 测量装置以记录一氧化碳 (CO) 和细颗粒物 (PM _2.5) WBT 测试期间炊具的辐射暴露。该模型的性能测试结果表明，与三石炉（14%）相比，热效率提高了32%。与三石炉相比，该炉子降低了 42% 的 CO 浓度和 99.5% 的 PM _2.5浓度。新炉子一小时的平均浓度暴露（3.1 μg/m ³ CO）符合世界卫生组织室内空气质量标准。此外，该炉子的燃料消耗量降低了 43%（每年/设备节省约 625 公斤燃料）。该模型实现的燃料节省导致 CO ₂气体排放量减少了 1.3 tCO ₂/年。因此，推测火箭炉比明火炉有相当大的改进，其适时发展可能会加强环保。因此，将烹饪技术从传统的传统炉灶转移到火箭炉可以减少室内空气污染物的排放和森林砍伐。
