Abstract

The characteristics of combustion processes are examined to gain insights into what factors influence the generation of polar vs nonpolar organics during combustion. The fuel type as well as the temperature and efficiency of the combustion process are influential. For highly-efficient combustion processes, thermal processing tends to convert the organics initially released via devolatilization to more nonpolar products. Under less efficient combustion conditions, the organic emissions tend to retain more of the compositional characteristics of the fuel being burned. 1 Introduction Aerosols containing highly-polar organics are of particular interest from an atmospheric standpoint. The light-scattering properti
