Modernization of the UG2-3-26 Electrostatic Precipitator to Increase its Operating Efficiency

Abstract

A large amount of combustion products, including ash, is released into the atmosphere during combustion of solid fuels in boilers. A major task is to reduce the emissions of ash in the atmosphere as much as possible. This article describes a reconstruction of an electrostatic precipitator for medium power boilers in which the ash collectors can be modernized to increase their operating efficiency. This redesign, with initial charging of ash particles, differs from similar systems in its simplicity and cheapness. Recommendations are given for operation of electrostatic precipitators and the results of a reconstruction of an ash collector system are described. This reconstruction method can be used in solid fuel-fired boilers equipped with electrostatic precipitators.
