The fossil fuel power plant consumed resources and discharged pollutants, of which the level not only connected with existence and development of projects themselves, but also affected the implement of energy conservation and emission reduction of the whole power industry, and held together the realization of the total target of general economical and social development of the country. Along with the sustainable development concept constantly deepening, green construction and green design techniques were widely adopted and applied. The green design technology were carried in the schematic design process of power plant, modular combination design was adopted, facility and function subsystem was optimized, new technique and new technology and new material were selected, effective water-saving measures were taken, optimized scheme of control system was put in practice, so the power plant could carry out sustainable development of itself, moreover acquire favorable economic and social and environmental benefits. The thesis aims to provide some beneficial experience accumulation for green design of the power plant based on preliminary study.
