An investigation into the use of electrode mass measurement to optimise an electrostatic precipitator unit

Electrostatic precipitators (ESP’s) can be simply described as particle collection devices and service a wide variety of industries. This particle collection can either be classed as a cleansing or product recovery (or both) process. They can be found in fossil fueled power generation plant (municipal incinerators, iron and steel industries (sinter plants, coke ovens), non ferrous industries, rock products (cement, lime), chemical and petrochemical (detarrers, de-oilers) They have been around for approximately 70 years and their fundamental principle of operation has not changed much during this time. What has changed is the demand on their operating efficiency. Environmental pressure as well as the loss of product has forced ESP’s to perform even better than before. This performance enhancement is two-fold : an increase in collection efficiency and a reduction in maintenance and wear costs. This project researches the use of mass measurement techniques to optimise the operation of ESP’s from both the above mentioned perspectives
