Abstract

Spontaneous combustion can be a significant problem in the coal industry, not only due to the obvious

safety hazard and the potential loss of valuable assets, but also with respect to the release of gaseous

pollutants, especially CO2, from uncontrolled coal fires. This report reviews methodologies for

measuring emissions from spontaneous combustion and discusses methods for quantifying, estimating

Abstract

There are various possibilities for incorporating biomass into coal-fuelled processes and a number of

these are already being deployed commercially. Others are the focus of ongoing research and

development. Biomass materials can vary widely, although the present report concentrates mainly on

the use of woody biomass in the form of forest residues. Potentially, large amounts are available in

Abstract

IGCC has today reached a status where experience is available from first and second generation

plants, built in the 1970s/1980s and in the 1990s respectively, as commercial-scale demonstration

plants for coal-based applications. These plants feature variations on gasification technology and

subsequent environmental controls and in operating them a number of technical and commercial

Abstract

Improving the efficiencies of the large number of older coal-fired power plants operating around the

world would give major savings in CO2 emissions together with significant other benefits. This report

begins with a summary of the ways efficiency can become degraded and of the means available to

combat the decrease in performance. These include improvements to operating and maintenance

Abstract

Global consumption of commercial energy totalled 18 Gt of coal equivalent in 2010. With a 28%

share, coal ranked second after oil as one of the major sources of primary energy and natural gas (at

21%) ranked third. Gross power generation with coal was approximately 41% and gas 22%. Natural

gas as a global commodity is growing rapidly with the advent of unconventional sources such as shale

Abstract

While pulverised coal combustion (PCC) remains the dominant technology in the power generation

sector, a significant minority of plant commissioned is based on circulating fluidised bed combustion

(CFBC). CFBC offers specific advantages over PCC, particularly in the utilisation of low quality

coals, and mixtures of coal with other fuels, including wastes. Since its initial deployment, CFBC has

Abstract

Electrostatic precipitators (ESP) are the dominant type of particulate control in pulverised coal

combustion (PCC) plant; fabric filters (FF) play a smaller role. Environmental pressures and

subsequent tighter regulations have lowered emission limit values (ELV) for particulate matter from

PCC plant, and they are now extending to specific toxic metals, such as mercury. Lower ELV are

Abstract

This report examines the current energy outlook for the Philippines in regard not only to coal but also

other energy resources. The history of the power sector, current state of play and future plans to meet

the increasing energy demand from a growing population are discussed. There is also analysis of the

trends for coal demand and production, imports and exports of coal and the types of coal-fired power

Abstract

Coal mine sites can have significant effects on local environments. In addition to the physical

disruption of land forms and ecosystems, mining can also leave behind a legacy of secondary

detrimental effects due to leaching of acid and trace elements from discarded materials. This report

looks at the remediation of both deep mine and opencast mine sites, covering reclamation methods,

Abstract

Mongolia is a very large, landlocked country, with a small population, located between Russia and

China. In the last two decades, it has begun reforms to move from a centrally-planned economy

towards one with market characteristics. At the same time, geological surveys have shown it is rich in

natural resources, especially coal, copper and gold, as well as silver, uranium, molybdenum, iron, tin,
