住宅固体燃料燃烧是许多污染物的主要来源，对空气质量和人类健康产生重大影响。目前正在使用改良的炉灶，特别是一些现代化的气化生物质炉灶，以减轻家庭和环境空气污染。在中国湖北省实地测量了改进的金属炉（n = 11）和现代气化炉（n = 8）燃烧木材的煤燃烧污染物排放。CO，TSP，OC，EC和多环芳烃的排放量从煤燃烧的改进铁炉一般低于以前报道的结果，在传统的炉灶。从木材燃烧的气化炉炉中的污染物，排放量低于文献报道的值，木材燃烧的传统炉灶，在改进的炉灶，但似乎高于在实验室测试中的气化炉炉的颗粒。数据稀少和方差较大的局限性导致统计意义不显著。与依赖煤炭的家庭相比，使用木材燃烧的家庭的目标污染物日排放量更高。气化炉炉有相对较高的热效率，但大多数空气污染物的排放量，每交付的能量没有显着不同的改进铁炉从煤燃烧。此外，OC，EC和多环芳烃的排放量较高，这表明在设计未来的清洁炉灶干预计划时需要谨慎和额外的测试。
Residential solid fuel combustion is a major source of many pollutants, resulting in significant impacts on air quality and human health. Improved stoves, especially some modern gasifier biomass models, are being deployed to alleviate household and ambient air pollution. Pollutant emissions from coal burning in improved metal stoves (n = 11) and wood combustion in modern gasifier stoves (n = 8) were measured in field in Hubei, China. The emissions of CO, TSP, OC, EC, and PAHs from coal burning in the improved iron stoves were generally lower than previously reported results for coal in traditional stoves. For pollutants from wood combustion in the gasifier stoves, the emissions were less than literature-reported values for wood burned in traditional stoves, comparable to those in improved stoves, but appeared to be higher than those for pellets in gasifier stoves in laboratory tests. The limitations of scarce data and large variances result in statistical insignificance. Daily emissions of targeted pollutants per household were found to be higher for wood burners, compared with households relying on coal. The gasifier stove had relatively high thermal efficiencies, but emissions of most air pollutants per delivered energy were not significantly different from those from the coal burning in improved iron stoves. Moreover, higher emissions of OC, EC, and PAHs were observed, indicating that caution and additional testing will be needed while designing future clean cookstove intervention programs.
