Investigation of burning rate on particullate matter emission factor of rice straw burning (case studi in lombok island, indonesia)

Abstract

This study investigates the emission factor arising from the agriculture waste burning especially rice straw burning. This research is a preliminary study to look further about the health impacts that occur due to the biomass burning that often occurs in Lombok island. The Laboratory study has been conducted to quantify the emission factor that looks into different burning rate related to the real condition in the field to estimate the health impact. The burning rates were varied into three different burning conditions, namely fast burning (13 m/s), medium burning (9 m/s) and slow burning ( 4 m/s). The concentration of the particle emissions (PM10 and PM2.5) were measured using a Handheld Air Tester (Hinaway, model CW-HAT200S) and a Digital Dust Monitor (Kanomax, model 3443). The emission factor is quantified by the total particle concentration divided by the burned fuel. The result shows that the burning rate determines the particle emission factor. The fast burning produces the particles the lowest PM10 and highest PM2.5 emission factor otherwise the slow burning results in the particle particles the highest PM10 and lowest PM2.5 emission factor.
