Air Pollution Control. Dipak K. Sarkar, in Thermal Power Plant, 14.2.23 Basic properties of the gas and dust particles. A precipitator is designed specifically for an ash produced by coal containing a certain amount of sulfur; if coal with different sulfur content is burned, the efficiency will vary. A coal with lower sulfur content may give satisfactory
electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues. The precipitator functions by applying energy only to the particulate matter being collected, without significantly impeding the flow of

Gas explosion, which is the main type of accidents reported in coal mines, comes with serious economic and safety consequences. The present work adopts the “glass heart” model for assessing the vulnerability of coal mines to gas explosions based on a constructed gas explosion vulnerability assessment index system.

Collection efficiency measurements of selected fly ash samples (from coal fired boilers) were carried out on a laboratory testing bench in a horizontal electrostatic precipitator model. View Show
A low efficiency (65%), high throughput cyclone is considered for precleaning flue gas and the ESP is designed for removal of the remaining 35% flyash from the flue gas. It is observed that with 100% dust load, the ESP requires six fields per pass, whereas with cyclone as a precleaner, it requires only five fields per pass.

A major source of emissions in a kraft mill is the boiler for generating auxiliary steam and power. The fuels are coal, oil, natural gas, or bark/wood waste. See Chapter 1, "External Combustion Sources", for emission factors for boilers. Table 10.21 presents emission factors for a conventional kraft mill. The most widely used
In a Coalfired Thermal Power Plant, multiple highpressure boilers are in parallel operation to fulfil the demand for steam and power for the process plant. An excessive amount of carbon monoxide (CO) is present in the flue gas, which may lead to creating an uncontrolled explosion in the ESP. which is a very dangerous phenomenon
recovery system. Coalhandling operations may account for about 10% of the particulate load. Coal charging, coke pushing, and quenching are major sources of dust emissions. Wastewater is generated at an average rate ranging from 0.3 to 4 cubic meters (m 3) per ton of coke processed. Major wastewater streams are generated from the cooling of the
