Characterization of organic aerosol produced during pulverized coal combustion in a drop tube furnace

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 thos...

Sulfur 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 ...

Organic 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...
