Abstract: According to the research about the recent developments of environmental protection technology in developed countries, the newest environmental protection technology for 600MW and 1000MW units in their thermal power plant were introduced. The design characteristics and technical routes for the environment friendly power plants were summarized, and a revelation was obtained that the environmental technique routes should be pluralism, and the comprehensive environment protection process conceptions for coal fired power plant should be set up. An outlook on the development of efficient flue gas treatment system for our thermal power units was given in this article.

Key words: high efficient flue gas treatment system, environment friendly power plants, new environmental protection process, flour dust, demercuration, revelation
