Environmentally Clean Technologies of Coal Combustion

Coal is one of the major fuels in Ukraine where its environmental impact is much higher than that of nuclear energy, provided that there are no accidents. Yet there is no alternative to coal, for natural gas can only cover the most urgent household and industrial needs, not to mention the country's indebtedness for its imports. The question of environment-friendly combustion of coal is therefore highly topical.

It is of special importance to the Lower Dnieper region where Pridneprovsk, Zaporizhia and Krivoi Rog steam power plants, Europe's biggest, are operated alongside with hundreds of smaller plants, cogeneration units and boilers. To abate pollution, one has to find its causes. With this in mind, a digest of recent materials found on the Internet is given in this issue. It has following sections:

• The environmental aspect of environmentally sound clean coal technologies
• Acceptability and abundance
• Environmental impacts of coal utilization
• Pollutant formation mechanisms
• Selection of processes to control pollutants
