厨房煤气燃烧对室内空气中氮氧化物浓度的影响

The Influence of Gas Combustion in Kitchen on Concentration of Nitrogen Oxides in Indoor Air

摘要: 为进一步了解燃气排放污染物造成的室内氮氧化物污染状况,对北京东郊使用管道煤气为炊用燃料的居民住宅室内空气中的氮氧化物进行了监测,分析了由于炊用煤气燃烧造成的氮氧化物的污染状况和影响因素.同时,对室内换气率、机械抽排作用等因素进行了研究,并讨论了单室模型描述燃气燃烧造成厨房空气污染的适用性.

Abstract: To comprehend the situation of indoor NO_x pollution caused by combustion of gas in kitchen, the indoor NO_x is monitored in residences east suburb of Beijing. Polluting situation and the main factors which exerted influence on it, such as air exchange rate and mechanical ventilation are discussed. The usability of the single compartment model is studied to discribe the NO_x pollution of combustion source in kitchen.
