Emission Inventory for Criteria Pollutants of a Thermal Power Plant

Abstract

Anand Kumar Varma S

The emissions inventory is the basic requirement for modeling of air quality, environmental monitoring and impact assessment. For any air pollution control program emission inventory is a key component. Emission inventory should be developed for acquiring emission data of significant amount. Fulfillment of air emissions inventory for a power plant identifies the source of air pollution. The air pollutants released from the entire source are measured to estimate the emission rates and emission concentrations. In the present study, we made an emission inventory for criteria pollutants of Suspended Particulate Materials (SPM), sulfur oxides (SOx), nitrogen oxides (NOx) and carbon monoxide (CO) from stationary sources of a thermal power plant. Fuel consumption and emission database was developed for Rayalaseema thermal power project (1050 MW). Emission factors are calculated for the pollutants. The project lies on latitude of 14°42’52”N and longitude of 78°27’29”E located at VV Reddy Nagar, Kadapa, Andhra Pradesh, India. The methods used for inventory presentation are Manufacturers’ design specifications and direct measurement. Results are compared from two methods.
