Abstract
Mercury is an element of growing global concern. The United Nations Environment Programme plans
to finalise a new global legally binding instrument on mercury by 2013, to coordinate actions to
reduce emissions of mercury.
It has been well established that Asia represents not only the region contributing to greatest current

Abstract
The present report reviews activities taking place focused on the eventual large-scale deployment of
carbon capture systems on coal-fired power plants. With this aim in mind, there are three main CO2
capture technology streams currently being developed and tested; these comprise pre-combustion
capture, post-combustion capture, and systems based on oxyfuel technology. Although numerous
other capture systems have been proposed, these three are currently the focus of most RD&D efforts

Abstract
Pulverised coal firing has been the dominant technology for generating power in utility boilers for
almost a century. During this period, boiler designs have evolved through an accumulating collection
of knowledge that has led to many empirical relationships that still guide current and future design
directions to some degree. In the late 1940s the developed nations began to undertake coal research

Abstract
In most discussions of systems for capturing CO2 from coal-fired power plants, three options are
described. These are:
* post-combustion capture;
* oxyfuel combustion;
* pre-combustion capture.
Recently, some researchers have realised that it may be possible to pick and choose among the

Abstract
Trace elements are emitted during coal combustion. The quantity, in general, depends on the physical
and chemical properties of the element itself, the concentration of the element in the coal, the
combustion conditions and the type of particulate control device used, and its collection efficiency as
a function of particle size. Some trace elements become concentrated in certain particle streams

Abstract
In recent years, there has been a convergence of international trade with traditional domestic markets.
As imports continue to increase in many coal producing regions, the influence of trade on domestic
markets has been twofold. Firstly, imported coal displaces domestic production and, secondly,
international price trends may drive prices of what remains of the indigenous market for coal.

Abstract
Low rank coals have gained increasing importance in recent years and the long-term future of
coal-derived energy supplies will have to include the greater use of low rank coal. However, the
relatively low economic value due to the high moisture content and low calorific value, and other
undesirable properties of lignite coals limited their use mainly to power generation at, or, close to, the

Abstract
The efficiency of a fossil-fired plant has a direct effect on its CO2 emissions. Efficiencies of coal-fired
power plants vary considerably around the world, and there is a potential for major CO2 emissions
savings by upgrading or replacements. This report provides estimates of the potential emissions
savings through efficiency improvements and plant replacements using modern systems (clean coal

Abstract
This report provides a review of the various options being pursued to reduce carbon intensities in five
developing countries, namely Brazil, China, India, Indonesia and South Africa. These are major
emerging economies, all of which are vulnerable to adverse effects from climate change, with their
governments having to balance economic, environmental and social priorities. All have large carbon
