The Effective Collection of Fly Ash At Pulverized Coal

At Pulverized Coal-Fired Plants The relationship between sulfur in coal, boiler exit gas temperature, and the carbon por­ tion of fly ash have a major effect on the electrical properties of fly ash. Whether effective collection of fly ash is obtained by the electrostatic precipitator installation alone or the

Basic Electrostatic Precipitator (ESP) Operation

An electrostatic precipitator (ESP) is an effective method of particulate collection in power generation applications. Its history dates back to the early 20th century. Of course, technology upgrades to enhance performance have continued for nearly as long. We have prepared a two-part article discussing ESP operation and some of the available upgrades and modifications now available for new
