Electrostatic Precipitator (ESP) Explained
The electrostatic precipitator functions by charging particulates within a gas stream as the gas flows through the ESP. These negatively charged particulates are attracted to positively charge large flat plates within the ESP, where they gradually accumulate upon the surfaces of the plates. Once a significant number of particulates have accumulated on the plates, …

Coal Pulverizers
Coal mills or pulverizers play a very essential part in the coal-fired power production system. Coal mills grind the coal into fine powder, and the primary air entering the mill dries and drives the coal into the power plant furnace for combustion.
