Selection Of Desulphurization Project And Expected Results Evaluation In Daihai Power Plant

Sulfur dioxide is one of the major pollutants of the atmosphere, is the main cause ofacid rain. Thermal power plants as a major source of emissions of sulfur dioxide, itstransformation is an important measure desulphurization sustained massive emissions ofsulfur oxides control. However desulphurization transformation typically involves manyaspects of economic, technology, resources and environment, involving a number offactors, both qualitative and quantitative, both deterministic uncertainty there is acomplex decision problems. Therefore, how to operate based on the actual production ofcoal-fired power plants, qualitative indicators and quantitative factors scientific andrational analysis of desulphurization transformation involved, assessment and preferredlow cost, effective, affordable and technologically advanced desulphurizationtransformation program, is an urgent problem to control nitrogen oxide emissions ofcoal-fired power plants to be addressed first.Based desulphurization plant project Daihai actual situation, the first principle ofsulfur oxides generated for analysis, and then combine the theory of project management,targeted comprehensive evaluation. On the index selection, consider both comprehensiveand take into consideration from environmental, economic and technical performance ofthe three, but also with the actual operation of the project management, select a projectschedule management and project quality management into two typical indicators indexsystem go, which makes the index system not only scientific theory, it is practical tooperate. On the evaluation method, on the basis of common evaluation methods conducta comprehensive study on the merits of the various evaluation methods, disadvantagesand scope of the analysis to select the final comprehensive evaluation method based ontriangular fuzzy numbers. Finally, the use of a comprehensive evaluation method basedon triangular fuzzy numbers desulphurization plant project Daihai empirical analysis, andfinally selects the optimal technical solution.Fuzzy comprehensive evaluation of Daihai power plant desulphurization technologysolutions for its economic choice for the desulphurization transformation technologyprovides a reasonable basis, avoiding the desulphurization plant blindness in the choiceof technical solutions, the desulphurization of coal-fired power plants for other similartransformation provides a useful reference.
