diesel exhaust particles are a complex mixture of thousands of gases and fine substances that contain more than 40 different environmental contaminants. being exposed to these exhaust particles (called soot) can cause lung damage and respiratory problems. diesel particulate filters are used in many countries for mobile sources as a legal obligation to decrease harmful effect of these fine parti...

In this paper a power electronic emulation of an electrostatic precipitator is presented. Precipitator power supplies can be tested under real power and operating conditions up to 200 kVA. Energy consumption of the system is very low, because the energy which is drawn by the emulation converter is fed back into the power grid. Therefore, just the power losses have to be provided by the grid. It...

The effective collection of fly ash in pulverized coal-fired plants which utilize electrostatic precipitators depends primarily on the effect of coal sulfur content, the gas temperature, and the carbonaceous content of the fly ash on the precipitator electrical power input. While the majority of precipitator installations are effective fly ash collectors, an abnormal change in any of the above ...

indicate a near-100% deposition efficiency of the aerosol entering the precipitator. The final objective is to have a precipitator, for which the particle deposition rate can be calculated as a function of particle size and operating conditions.

− Power quality measurement analysis of the electrostatic precipitator in thermal power plant under different working conditions is presented in the paper. Control of electrostatic precipitator is realized by digitally controlled antiparallel thyristors. In the first regime (continual) the constant firing angle of thyristor is set in dependence of the reference current. In other regime (intermi...

Homogeneity of the flue gas flow through chamber an electrostatic precipitator is one basic influencing parameter on dedusting efficiency. This paper presents results a multiobjective optimization study controlling devices 324 MWe lignite fired unit A4 Thermal Power Plant "Nikola Tesla" in Serbia. The aim was to achieve better homogeneity cross-section compared original design. Additional const...

Characteristics of biomass used as fuel and distinct ash flows in a thermal power plant with BFBC (bubbling fluidised bed combustion) technology were studied. An integrated approach involving chemical composition, microscopy analysis, mineralogy, and thermal behaviour were used to characterize the ash. The ashes have a low unburned content, typically below 3 wt.% (dry basis), with higher values...

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...
