民用燃气灶污染物排放特性研究

The emission of pollutants from gas appliances for domestic cooking

作者调查了北京地区使用 TZ 2—A,JZ 2—A,YZ 2—A型家用燃气灶分别燃用天然气、焦炉煤气和液化石油气,在正常燃烧条件下的 CO、NO_x、SO_2和颗粒物的排放特性,在此基础上探讨了厨房在不同的通风换气条件下,对室内空气污染的改进效果。此外,还提出了采集炉灶大烟尘量的专门采样方法。

A survey was carried out in Beijing to determine the emissions of CO,NO_x,SO_2 and particles produced by the TZ 2-A,JZ 2-A and YZ 2-A type domestic cooking appliances using natural gas, coke gas and liquid petroleum gas as fuel,and the improvement of indoor air pollution under dif- ferent ventilation in kitchen room was investigated.In addition,a special sampling method for col- lecting large mass of particles from cooking appliance was introduced.
