The motivation in studying the physico-chemical characteristics and transient behavior of particulate matter emitted during combustion of fossil lies in the growing interest with regards to their human health and atmospheric impacts.
The behavior, physical, and chemical properties of particulate emissions produced from combustion aerosol standards (CAST) using propane and diesel fuel (DF) with or without additives and ship diesel engine using heavy fuel oil (HFO) and DF were studied by using aerosol online instrumentation techniques.
Particulate evolution and characteristics depended primarily on engine load and fuel-to-air-equivalence ratio in a ship diesel engine and diffusion flames, respectively.
Metal additives in a DF flame burner resulted to an increase in mixing of organic functional groups in the emitted particles.
Based from the results in this study, the formation of particulates from fossil fuel combustion was simplified based on the combustor, combustion conditions, and fuel components.
