Resumo:
In spite of the environmental impacts caused by the use of fossil fuels, the mineral coal
has its use predicted to extend for more than 200 years, because it presents the largest world
reservations, being responsible for about 40% of the electric power globally generated. This
reality, alied with other economic and environmental aspects, have been taking the effort of
many countries in the last decades in the sense of development of technologies in order to
achiev more efficient and cleaner use. The present work has the purpose to describe the main
technologies for combustion of the coal and their control of the main their generated
pollutants, which takes part of the denominated of Clean Coal Technology program (CCT)
developed and applied in the countries that uses coal as their main fuel. This research has its
fover in obtaining the conclusions about the technologies used nowadays, and also on
technologies in the ones under and development. A calculation example is shown the end of
this work aiming to demonstrate the efficiency at one of these technologies regarding the
emission of pollutant.
