农村贫困地区改良炉灶降低室内空气污染的效果评价

Assessment on Improved Stoves to Reduce Indoor Air Pollution in Poor Rural Areas

目的研究中国农村贫困地区采用改良炉灶措施在降低室内空气污染方面所达到的效果。方法选择污染物排放指标PM10、502、CO和热工性能指标燃料消耗量、炊事热效率，综合评价改良炉灶的性能，确定改良炉灶的效果。结果与传统炉灶相比，改良炉灶PM10、CO、SO2排放浓度分别平均降低了93％、79％和68％，燃料消耗量降低30％-50％，炊事热效率平均提高38％。结论改良炉灶是中国农村贫困地区降低室内空气污染的有效干预手段之一。

Objective To study the effect of improved stoves to reduce indoor air pollution in poor rural areas in China. Methods The emission rates of PM10 , SO2, CO and fuel consumption, heat efficentcy in cooking of stoves were selected to assess the intervention effect. Results Compared with traditional stoves, the concentration of PM10, CO and SO2 from improved stoves decreased by 93%, 79% and 68% respectively, the fuel consumption also decreased by 30% -50%, the heat efficiency in cooking averagely increased by 38 %. Conclusion Improving stoves is one of the effective intervention methods.
