Concentrating solar thermal power system can provide low carbon, renewable energy resources in coun-tries or regions with strong solar irradiation. For this kind of power plant which is likely to be located inthe arid area, natural draft dry cooling tower is a promising choice. To develop the experimental studieson small cooling tower, a 20 m high natural draft dry cooling tower with fully instrumented measure-ment system was established by the Queensland Geothermal Energy Centre of Excellence. The perfor-mance of this cooling tower was measured with the constant heat input of 600 kW and 840 kW andwith ambient temperature ranging from 20°Cto32°C. The cooling tower numerical model was refinedand validated with the experimental data. The model of 1 MW concentrating solar thermal supercriticalCO2power cycle was developed and integrated with the cooling tower model. The influences of changingambient temperature and the performance of the cooling tower on efficiency of the power system weresimulated. The differences of the mechanism of the ambient temperature effect on Rankine cycle andsupercritical CO2Brayton cycle were analysed and discussed. |
