测量了使用各种固体燃料的烹饪和空间加热过程中向室外空气排放的污染物，并根据厨房性能测试估计了每日家庭排放量。蜂窝煤燃烧的排放因子最低，而木材的使用产生的污染物最高。空间加热的每日排放量明显高于烹饪，与木材烹饪和泥炭空间加热相比，使用蜂窝煤烹饪和原煤加热可减少28%，24%和25%的CO，PM10和PM2.5。在燃烧初期，由于空气供应不足和燃烧温度较低，导致燃烧初期的排放量比稳定期高得多。然而，在高温稳定燃烧阶段后期形成的细颗粒物的质量百分比较高，可能会增加潜在的吸入暴露风险。(C)2015爱思唯尔有限公司版权所有。
Pollutant emissions into outdoor air from cooking and space heating processes with various solid fuels were measured, and daily household emissions were estimated from the kitchen performance tests. The burning of honeycomb briquette had the lowest emission factors, while the use of wood produced the highest pollutants. Daily emissions from space heating were significantly higher than those from cooking, and the use of honeycomb briquette for cooking and raw coal chunk for space heating reduces 28%, 24% and 25% for CO, PM10 and PM2.5, compared to wood for cooking and peat for space heating. Much higher emissions were observed during the initial phase than the stable phase due to insufficient air supply and lower combustion temperature at the beginning of burning processes. However, more mass percent of fine particles formed in the later high temperature stable burning phase may increase potential inhalation exposure risks. (C) 2015 Elsevier Ltd. All rights reserved.
