AI Technical Summary
Existing solar gas turbine power generation systems suffer from complex high-temperature heat exchanger structures, high manufacturing costs, large heat losses, and material fatigue problems. Meanwhile, small gas turbines rely on fossil fuels, resulting in high fuel consumption and high carbon emissions.
The gas turbine power generation system adopts solar direct heating and staged combustion, which eliminates the traditional heat exchanger. The compressed air is directly heated by the main body of the solar direct heating collector, and fossil fuels are used for auxiliary heating when necessary through the staged combustion unit. Combined with the serpentine or spiral air heating channel and insulation layer design, it achieves efficient solar energy utilization.
It improves the overall thermal efficiency of the system, reduces fossil fuel consumption and carbon emissions, lowers equipment failure rate and operating costs, and meets the requirements of low-carbon and environmentally friendly development.
