บทคัดย่อ

This research focuses on improving the solar updraft tower efficiency by including a solar collector with parabolic trays and molten salt as heat storage to the system. The objectives of this research are (1) to design a solar thermal updraft tower with molten salt as heat storage for electricity generation by studying and optimizing its parameters and (2) to assess the efficiency of the system and to compare it with the original design. ANSYS CFX is used to calculate the power output of the system. The first parameter is the tower height to roof radius ratio which ranges between 0.2 - 2.2 while fixing the surface area of solar thermal updraft tower as a constant value. The baseline dimension of the tower is taken from the 50kW Manzanares prototype in Spain. The study shows that electrical power output increases with the tower height to roof radius ratio. Two pipe arrangements, namely a reversed pipe layout and the single pipe layout are studied. It is found that the single pipe layout yields a higher energy output. The single pipe arrangement is then further studied to assess the effect of pipe number with 12, 24, 36, 48 and 60 pipes evenly spaced around the tower in the radial direction. It is found that the system with 36 pipes gives the lowest ratio of oil used to power generated. The results show that solar thermal updraft tower with 36 single pipes generates up to 157.15 kW. The efficiency of the system is 8.93% which is 96 times higher than the original solar thermal updraft tower efficiency of only 0.09%. ฉ 2018 IEEE.
