Research on Solar Supported Coal-Fired Power Generation of Practical Operation Conditions

Based on the purpose to reducing coal consumption rate and environmental pollution of coal-fired power generation and the limitation of present researches on solar integrated with coal-fired power generation when it is in the design condition, it is analyzed that solar support coal-fired power generation on practical operation conditions and compared the coal saving ratio of integration mode on different reference operation conditions. It is found that all of the coal saving ratio of integration modes on 75%THA is better than other integration systems. It is analyzed that the thermal economy of solar replacing the 2^nd extraction steam on 75%THA, the result showed that the coal saving effect and environmental protection effect of integration system could be desired.
