Low resistive particulate matter (PM) generated from marine engines or diesel generators has been known to be difficult to collect by the conventional electrostatic precipitators (ESP). In the present study, the double-cylinder type ESP (DC ESP) was developed to remove low resistive diesel exhaust particles. Two ESPs, namely, the conventional singlecylinder type ESP (SC ESP ) and DC ESP were in...

The precipitation of particles in an electrostatic precipitator (ESP) results in striking dust patterns at the collecting electrodes, strongly depending on forces of the electrohydrodynamic (EHD) field in the duct. Due to precipitator geometry, electrical operation status, and process parameters, areas of high and low dust density are visible. Since latest results show a direct correlation of p...

Low-medium temperature application of selective catalytic reduction (SCR) denitration in cement flue gas was established and investigated this study. The 2000 h continuous operation shows the concentration NOx at outlet can be maintained 24 mg/Nm3 on average, while due to increase SO2 gas, increased 57.5 after long time operation. sulfur deposition is main reason for catalyst deactivation, stil...

With the Nation's coal-burning utilities facing the possibility of tighter controls on mercury pollutants, the U.S. Department of Energy is funding projects that could offer power plant operators better ways to reduce these emissions at much lower costs. Mercury is known to have toxic effects on the nervous system of humans and wildlife. Although it exists only in trace amounts in coal, mercury...

For the Polish power industry, basic fuel is hard coal and lignite, which contains significant amounts of mercury. Current emission standards in European Union (IED directive near future BAT conclusions) create conditions for investment flue gas cleaning installations coal-fired plants. During combustion coal, mainly metallic mercury (Hg 0 ) produced, difficult to remove from dedusting (electro...
