Efficient closed gas power generation system capable of achieving 100% carbon recovery
2015
The invention belongs to the technical field of gas power generation and relates to an efficient closed gas power generation system capable of achieving 100% carbon recovery. The gas power generation system mainly comprises an oxygen generation system 1, a fuel supply system 2, a combustion chamber 3, a turbine 4, a power generator 5, a high temperature heat regenerator 6, a low temperature heat regenerator 7, a cooler 8, a water separation and recovery device 9, a main gas compressor 10, an auxiliary gas compressor 11 and a carbon dioxide storage system 12. The system solves the technical problem of low efficiency of the carbon separation and recovery system of the existing fossil power plant. The system realizes 100% carbon recovery through processes, has carbon recovery effects significantly better than those of the carbon recovery system of the current fossil power plant, and can increase the efficiency of gas power generation by 10% or more. In addition, the system is free of an additional carbon recovery system or equipment and saves the investment cost of the power plant.
