| Zusammenfassung |
| This paper, which focuses on emissions from China's coal-fired power plants
during 1990–2010, is the second in a series of papers that aims to develop a
high-resolution emission inventory for China. This is the first time that
emissions from China's coal-fired power plants were estimated at unit level
for a 20-year period. This inventory is constructed from a unit-based database
compiled in this study, named the China coal-fired Power plant Emissions
Database (CPED), which includes detailed information on the technologies,
activity data, operation situation, emission factors, and locations of
individual units and supplements with aggregated data where unit-based
information is not available. Between 1990 and 2010, compared to a 479 %
growth in coal consumption, emissions from China's coal-fired power plants
increased by 56, 335, and 442 % for SO2, NOx, and
CO2, respectively, and decreased by 23 and 27 % for PM2.5
and PM10 respectively. Driven by the accelerated economic growth, large
power plants were constructed throughout the country after 2000, resulting
in a dramatic growth in emissions. The growth trend of emissions has been
effectively curbed since 2005 due to strengthened emission control measures
including the installation of flue gas desulfurization (FGD) systems and the
optimization of the generation fleet mix by promoting large units and
decommissioning small ones. Compared to previous emission inventories, CPED
significantly improved the spatial resolution and temporal profile of the power
plant emission inventory in China by extensive use of underlying data at
unit level. The new inventory developed in this study will enable a close
examination of temporal and spatial variations of power plant emissions in
China and will help to improve the performances of chemical transport models
by providing more accurate emission data. |
