Coupling performance analysis of a solar aided coal-fired power plant

摘要: Abstract Coal-fired power plants are the dominant form for generation in many countries, even though they main contributor to current environmental crises. The solar aided coal-fired plant is an attractive new way reduce coal consumption by using energy. From perspective of operational mechanism and coupling property, all-condition model proposed this paper. operation N600-24.2/566/566 supercritical hybridized with parabolic trough collectors simulated Matlab/Simulink fuel saving mode. And a evaluation index energy reasonably assess contribution plant. When steam used replace extraction feedwater heating system, change steam, reheat discussed as property taken into account. Furthermore, thermal economic analysis carried out optimize replacement entrance inlet field. Moreover, efficiency output high pressure cylinder, intermediate low cylinder when replaced system. Finally, shock caused fluctuation Direct Normal Irradiance assessed. It found that strong affects quality significantly.
