Abstract
Emissions standards are becoming more stringer, as a result new technique are being applied in the existing Tuticorin Thermal Power Plant (TTPS) by using Imported and Indian Coal. Electrostatic Precipitators (ESP) are used to control fly ash. The Indian coal burned in TTPS is having low calorific value 3300 Kcal/kg., and high ash content 42.5%. Thus compared to Imported coal, Indian coal generates about 8 to 10 times more ash for collection for similar electricity generation. Thus ESPs in India is having lower collection efficiencies than the ESPs in other Developed Countries In this paper we discuss Ammonia Injection method which are being applied in different power plants in India to improve the collection efficiencies of ESP. Blending of coal is done and Ammonia is injected in different concentration there by reducing the SPM ranges from 900 to 120 mg/Nm3. The paper describes the experiments and analysis. The results obtained by SPM range is brought below 150 mg/Nm3 as prescribed by Pollution Control Board and in turn reduces pollution.
