Emission Characteristics of Particulate Matters and VOCs in Cow Dung Combustion

摘要

Emission Characteristics of Particulate Matters and VOCs in Cow Dung Combustion Biomass fuel has been greatly used for cooking especially in developing countries and several studies have concentrated on the toxicity level of the combustion emissions. This study focused on the characteristics of particulate matter(PM) and VOCs from cow dung combustion. Data collection and results from the combustion were taken from the usage of a dual cone calorimeter, in which it showed that the heatflux, 50kW/m2 has the highest CO2 yield having 1,407.7138.2 mg/kg. When the temperature is high, the combustion will also increase. The concentrations of PM and VOCs were determined using a dust spectrometer and gas chromatography/mass spectrometry, respectively. The outcome of the tests presented that PM10 concentration were highest at 15kW/m2 with a total of 1,660.0709.5 g/m3. On the other hand, VOCs like benzene and toluene were detected during lower combustion temperature. Higher heat rate may cause an ample amount of CO2 concentration release, however, it also causes some VOCs and ultrafine dusts undetected. The generation of ultrafine dusts and VOCs was particularly high when the combustion temperature was low.
