Abstract

A series of source tests were conducted to characterize emissions of nitrogen oxide(NOx, NO, $NO_2$), carbon mon oxide(CO), carbon dioxide$(CO_2)$ and total VOCs from portable combustion devices in steady-state using well-mixed chamber. Since use of portable gas range is widespread in houses and restaurants in Korea, it is important to characterize the emission of air pollutants and suggest optimum ventilation rate. Ranges of emission rates of air pollutants from portable gas ranges were $NO \;0.551\sim0.939mg/hr,\;NO_2\;0.354\sim1.080mg/hr,\;NO_x\;1.207\sim1.631mg/hr,\;CO\;1.389\sim4.21mg/hr,\;CO_2\;2426.823\sim2973.495mg/hr$, and VOCs $0\sim0.119mg/h$. Mean of personal exposure and indoor environment level of $NO_2$ by combustion of portable gas range were 74.7 ppb and 65.4 ppb, respectively, suggesting persons using portable gas range in houses and restaurants might be highly exposed. Required ventilation rate to control the air pollutants emitted from portable gas range was maximumly $3.131m^3/hr$ on the basis of $NO_2$ indoor air quality standard.
