Solar chimney power plant which can realize continuous power generation is a potential power generation technology. Based on the heat transfer theory and hydrodynamics theory, a comprehensive heat transfer and flow model of solar chimney power plant was proposed, and the characteristics of unsteady temperature field and flow field of the system were analyzed. With Manzanares solar chimney power plant as the geometric prototype, the performance of plant generation output and generation stability were studied in condition of different thickness of heat storage layer, different specific heat capacity and thermal conductivity of heat storage medium. The numerical stimulation results showed that above three factors significantly affected the power generation output and generation stability. Thus, the optimization of the three factors was achieved in this paper, which provides the basis for the solar chimney heat storage system design.

The three difference structural heat storage devices are designed used paraffin as phase change heat storage materials for the chimney power plant system with vertical collector, and the FLUENT software is used to study the heat storing and releasing capacity of four different structural heat storage devices. The results are shown that: in the same case, The heat storage and heat release abilities of the devices with different surfaces are studied through numerical simulation, the results show that: the heat storage ability of the device with fins is much better than that of flat-plate device, and the heat storage ability of the device with longitudinal fins is a little better than that of the device with lateral fins. So for the solar chimney power plant system with vertical collector, the heat storage device with longitudinal fins can be chosen in consideration of the flow resistance and heat transfer ability. These results are the theoretical basis for the actual construction of the solar chimney power plant system with vertical collector.

Solar Chimney Power Plant

Solar energy is a renewable energy source that can generate electricity. When there is much solar radiation, there is not always a need for all the energy from the solar, and when the weather is cloudy there may be too little energy to meet demand. Thus, it is often wise to implement energy storage in systems with a large share of renewable energy. Latent heat storage is one of the most efficient ways of storing thermal energy. Sodium Sulfate Decahydrate (Glauber’s salt) has a larger energy storage density and a higher thermal conductivity. So the present work, built solar chimney power plant of 2m-radius of collector and a 4m chimney height integrated by phase change materials. Aim of designing and building solar chimney to estimate the effect of adding phase change materials as well as to examine the effect of inclination angle (16°, 8°). The results show that maximum temperature difference between collector exit and the ambient reached to 23.7°C for case (i) and for 17.7°C case (ii), the maximum air velocity reached 2.25 m/s that in case (ii) and reached 2.05 m/s in case (i).and maximum collector efficiency can be reached to 8.925% in case (ii).
