Formulation, application and evaluation of a stack emission model for coal-based power stations
Walvekar, P. P. & Gurjar, B. R.
Abstract
Estimation of coal power plant emissions is a
vital step to visualise emission trends with respect to spe-
cific policy implementations and technological interven-
tions so that their effectiveness in terms of emission
reductions and ambient air quality improvement can be
quantitatively assessed. However, research work concern-
ing stack emission estimations specifically for coal power
plants in India is limited. To bridge the present gap, we
present a plant-specific multi-year and multi-parameter
Coal Power Stack Emission Model. This model has been
developed to explore current and historical annual stack
emissions from a coal-based thermal power plant taking
into account essential variables such as coal characteristics,
process attributes and control equipment aspects, which
can significantly influence the stack emissions. This study
concentrates on development of Coal Power Stack Emis-
sion model and its application for the estimation of plant
and year-specific emission factors and stack emissions for a
coal-based power plant at Badarpur, New Delhi, for the
period of 2000-2008. The validation of Coal Power Stack
Emission model has also been successfully carried out by
comparing the trends of percentage change in annual
emission estimates and observed ambient air concentra-
tions of total suspended particles, PM
10
and sulphur diox-
ide at two nearby air quality monitoring stations, namely
Siri Fort and Nizamuddin.
