Characterization of organic aerosol produced during pulverized coal combustion in a drop tube furnace
نویسندگان
چکیده
Controlled bench scale pulverized coal combustion studies were performed, demonstrating that inorganic particles play a critical role as carriers of organic species. Two commonly-used aerosol mass spectrometry techniques were applied to characterize fine particle formation during coal combustion. It was found that the organic species in coal combustion aerosols have mass spectra similar to those generated by biomass combustion. Ambient measurements in Shanghai, China confirm the presence of these species in approximately 29–38 % of the sampled particles. With the absence of major biomass sources in the Shanghai area, it is suggested that coal combustion may be the main source of these particles. This work indicates there is a significant potential for incorrect apportionment of coal combustion particles to biomass burning sources using widely adopted mass spectrometry techniques.

Comment 1: “This article presents some interesting conclusions regarding the chemical mixing state of particles produced from the combustion of pulverised coal. It would be useful, however, to expand the discussion to cover differences between the single particle mass spectra reported here and those obtained for power generation-related coal combustion and domestic coal combustion in other prev...
متن کاملOrganic emissions from coal pyrolysis: mutagenic effects.
Four different types of coal have been pyrolyzed in a laminar flow, drop tube furnace in order to establish a relationship between polycyclic aromatic compound (PAC) evolution and mutagenicity. Temperatures of 900K to 1700K and particle residence times up to 0.3 sec were chosen to best simulate conditions of rapid rate pyrolysis in pulverized (44-53 microns) coal combustion. The specific mutage...
متن کاملSulfur Species in Particulates Emitted from Reducing Coal Combustion and Pyrometallurgical Furnaces
The method of X-Ray Photo-electron Spectroscopy is used to determine the chemical state of the sulfur species present in fly-ash samples produced by burning a number of pulverized coal samples under reducing conditions in a continuous combustion furnace. The influence of submicron metallic constituents present in the flue-gases of the pyrometallurical systems on the state of the sulfur species ...
