Fly Ash Resistivity of Indian Coals Generated in Indian Power Plants

Abstract
The properties of the coal used in different thermal power plants cross India vary widely, but posses less sulfur contents. As a result the ash resistivity of the fly ash is very high and it leads to develop back corona at the collecting electrodes even at comparatively low current densities, which affects the Collection efficiency of ESP. Knowledge of electrical resistivity is essential for sizing of ESP and to determine a strategy to improve its performance. A series of experiments have been conducted on the fly ash samples obtained from different power plants in India. Modified Empirical relations developed , which are based on chemical composition of fly ash for calculating the electrical resistivity, are used to calculate as theoretical value for given experimental conditions.
