Solar chimney power plants are an important solar energy system in terms of CO2 emissions and
maintenance costs. The system, which was first implemented in the Manzanares region of Spain in
the 1980s, has a chimney height of approximately 200 m and a collector diameter of 244 m. The
translucent collector is responsible for transferring the solar radiation falling on it to the system and
creating a closed cover. The thermal energy of the sun passes through the translucent collector and
reaches the system air and from there to the ground. Meanwhile, the system air is exposed to the
thermal effects of the sun and the solar radiation reaching the ground causes an increase in
temperature on the ground. The system air, whose temperature increases due to the solar radiation
falling on it and the convection effects on the ground, accelerates upwards with the vacuum effect
created by the high chimney in the collector centre, towards the chimney entrance, and from there
it accelerates upwards through the chimney. Meanwhile, electricity is produced by the turbine
positioned at a certain height inside the chimney. In the study, the maximum performance range for
the collector and chimney, which are the most important building blocks of the system, is examined.
The increase in chimney height and collector size not only improves the performance of the system,
but also causes a large increase in cost. Look for optimum values for collector size and chimney
height.
