Increased material efficiency in cookstove designs aids in reduction of specific fuel consumption, emissions and increased energy efficiency. In this work, three (3) improved biomass cookstoves with different combustion chamber materials (aluminium, ceramic clay and mild steel) were designed, developed and tested under the Water Boiling Test (WBT) protocol. The stoves design specifications were carefully altered to prevent significant variations in performance. The energy efficiency, specific fuel consumption and emission performance parameters of the three stoves indicated the ceramic clay combustion chamber as the material of choice in achieving the set target of Tier 2 of the International Organization for Standardization (ISO)/Technical Report (TR) 19867–3:18 voluntary performance targets.

炉灶设计中提高的材料效率有助于减少单位燃料消耗，排放并提高能源效率。在这项工作中，根据水沸腾测试（WBT）协议设计，开发和测试了三（3）种具有不同燃烧室材料（铝，陶瓷粘土和低碳钢）的改进型生物质炊具。炉子的设计规格经过仔细修改，以防止性能出现重大变化。这三个炉灶的能效，特定燃料消耗和排放性能参数表明，陶土燃烧室是实现国际标准化组织（ISO）/技术报告（TR）19867第2层设定目标的首选材料–3：18自愿绩效指标。
