Multi-pollutant control technologies will become more important in the future. This new membrane wet electrostatic precipitator (WESP) system is ideally suited to, and very cost effective for, removing PM2.5, SO3 and Hg after limestone wet flue gas desulphurization (WFGD) scrubbers in the utility industry. Several coal-fired utilities have been experiencing increased SO3 emissions from their ex...

The paper presents a theoretical analysis on the dynamic characteristics of the current-voltage characteristics of plate-type electrostatic precipitators (with three fields) from an electric power station. Measures were made with signal conditioning, data acquisition card, and PC. It was found that these characteristics can not be mathematically model, due to their permanent modification (have ...

Experimental data collected from different plate-type electrostatic precipitators used in a thermoelectric power plant has been analyzed. The following parameters were considered: the collection efficiency, average migration velocity of dust particles, velocity distribution of the gas in the input and output channels of precipitators. The average migration velocity of dust particles can be esti...

furnace division is one of the most polluted divisions ever known in the steel industry associated with several environmental pollutions. this study attempted to choose optimally, a pollution control system for dust emission from steel furnaces with the green and environmentally friendly approach. three electric smelting furnaces with 3, 6 and 12-ton output capacity were selected. the level of ...

Gaseous exhausts from various industries pollute the environment with fly-ash generally filtered by electrostatic precipitators (ESPs) before being released to atmosphere. This paper presents development of a controller for ESP power supply. The maintains voltage applied at its maximum average value duty cycle control that results in an improvement dust collection-efficiency. limiting factor ou...
