The document describes an electrostatic precipitator (ESP) used to clean dust particles from flue gases produced by a boiler in a steam power plant. It works by ionizing dust particles and using electric fields to attract the particles to collecting plates. Key components of the ESP include gas distribution screens, collecting and emitting electrodes, transformers, and rapping mechanisms to remove deposited dust from the plates. The document provides specifications for the ESP and bag filter house used at the SWPL plant, including dimensions, treated gas volumes, temperatures, voltages, and numbers of components. Factors that can affect ESP performance such as gas speed, temperature, rapping frequency, and voltage levels are also summarized.
