几十年来，住宅燃煤在中国北方的国内能源供应中发挥了重要作用，并将在可预见的未来继续发挥作用，尽管它也是严重空气污染的重要因素。要以生态友好的方式满足农村居民的日常烹饪和取暖需求，就必须采用更清洁的民用燃煤技术。一些报告建议，适当大小的煤有利于优化家用燃煤炉的性能。煤的大小（2.5厘米）细颗粒物（PM2.5）和16个美国环境保护署（EPA）的优先多环芳烃（16-PAHs）的排放量从自然交叉通风炉，在不同阶段（点火，高功率加热，低功率加热，斜升和高功率烹饪）的影响进行了分析。结果表明，减小煤的粒度可以提高热效率，减少污染物排放。当煤的粒度从> 2.5cm减小到
Residential coal combustion has played an important role in the domestic energy supply of Northern China for many decades and will do so for the foreseeable future, although it is also an important contributor to severe air pollution. Meeting the daily cooking and spacing-heating demands of rural residents in an eco-friendly manner necessitates cleaner-burning technologies for residential coal combustion. Several reports have suggested that appropriately sized coal be beneficial for optimizing the performance of domestic coal-fired stoves. The effects of coal size (2.5 cm) on fine particulate matter (PM2.5) and sixteen U.S. Environmental Protection Agency (EPA) priority polycyclic aromatic hydrocarbons (16-PAHs) emissions from a natural cross-draft stove, operating in different phases (ignition, high power heating, low power heating, ramping up and high power cooking) were analyzed in this study. Results indicated that decreasing the coal size enhanced thermal efficiency and reduced pollutant emissions. When the coal size decreased from >2.5 cm to
