New fossil fuel energy technologies - a possibility of improving energy efficiency in developing countries

摘要

The energy intensity in developing countries, especially in Eastern Europe and Former Soviet Union countries, is considerably higher than in industrialized countries. The development of new fossil fuel energy technologies might be a possibility to improve the energy efficiency and that way reduce the energy intensity in developing countries. Some of these new energy technologies: combustion in the pressurized fluidized bed, integrated combined cycle with coal gasification, combined cycle with natural gas as a fuel and fuel cell are shortly described. The principle of work for the facilities based on the above-mentioned technologies is described, and the basic characteristics and state of development are given. It has been emphasized that the facilities with those technologies have higher efficiency compared to classic thermal power plants, and that they polute considerably less the environment. The short overview of primary energy consumption, the share of different resources and the estimation of saving which might be realized by using new technologies are given.
