Factors affecting methyl chloride emissions from forest biomass combustion

Article Abstract:

Vegetative biomass burning produces the trace gas chloromethane. The factors which influence methyl chloride emissions from biomass combustion were investigated using regression analysis. The results showed that CH3-Cl emission factors are dependent on combustion efficiency, rate of heat release and fuel chloride level. Combustion conditions also had an effect on the amount of chlorine in fine particle emissions.

Measurement and modeling of air toxins from smoldering combustion of biomass

Article Abstract:

The presence of oxygenated organic compounds in condensed smoke of different types of biomass under smoldering, self-sustained smoldering and flaming conditions were analyzed using gas chromatography/mass spectrometry and gas chromatography/flame ionization detection. The results showed that 2-furaldehyde, vinyl acetate, acetol and methanol were the major condensible emissions.

Growth and structural change of combustion aerosols at high relative humidity

Article Abstract:

A tandem differential mobility analyzer was employed to measure the hygroscopicity of combustion aerosol particles. Sodium chloride particles exhibited a rapid increase in growth factor upon exposure to high relative humidity, while carbon particles shrank. On the other hand, particles emitted from a four-stroke spark ignition engine showed the reverse results.
