It is noteworthy that the percentage of young generation is even higher. The number of restaurants has increased dramatically in recent years. One of the most growing restaurants is charcoal barbecue restaurant and it has often become chainstore. The air pollution emitted from barbecue not only results in the deterioration of indoor air quality but also strongly impact outdoor air quality. Many studies have found that charcoal barbecue is one of major sources of air pollution. The purpose of this project is to investigate the air pollutants emitted from charcoal barbecue and then determine their emission factors including CO, CO2, Total Hydrocarbons, NOx, PM10 and PM2.5. Combustion experiments on three common charcoals will be performed under conditions including combustion temperature, flow rate, combustion stage ( flaming and smoldering stage). The effect of oil drop from barbecue foods will also be evaluated. The flue gas from combustion will be collected and analyzed for particulate PM2.5 and gaseous air pollutants including CO, CO2, NOx, Total Hydrocarbons. Basic characteristic experiments of charcoals will also be undertaken including heating value, water content, volatile component, fixed carbon, ash content, and elemental analysis. The sampling and analysis of particulate PM2.5 will include both optical principle and gravitation analysis of filter to obtain more accurate PM2.5 concentration. Furthermore, emission factors of air pollutants will be determined for common barbecue charcoals used in barbecue restaurants in Taiwan under conditions of combustion temperature and stages. The results of this project will help Environmental Protection Agency to establish the emission factors of air pollutants from charcoal barbecue restaurants .
