Kaji Eksperimental Solar Chimney Power Plant (Scpp) Dengan Concentrating Lens Disusun Dengan Pola Aligned
ABSTRACT
Solar chimney power plant (SCPP) is an efficient and environmentally friendly
renewable energy by utilizing solar energy as its main source. Based on the
obtained hypothesis, the use of concentrating lenses can increase the temperature
inside the solar collector. With increasing temperature, the speed of air to rotate
the turbine blades will increase, so that the power obtained will increase
maximally. This tool consists of 4 parts, namely: a buffer made of circular steel
reinforcement, a heat sink made of concrete and painted black to absorb more heat
and formed in a circle, a transparent cover or collector of clear plastic material,
and a concentrating lens with variations of 36 and 21 concentrating lenses. This
study aims to determine the temperature increase that occurs in the solar collector
using a concentrating lens, to determine the wind power potential and efficiency of
the solar collector using 36 concentrating lenses, 21 concentrating lenses and
without using concentrating lenses. The results of this research are, by the using of
concentrating lens that totalling of 36 and 21, it produces maximum wind power
of 3.006 W and 2.478 W with an average of 0.929 W and 0.761 W per day, while
without the using of concentrating lens, it produces 1.483 W with an average of
0.486 W per day, and it obtained the collector efficiency by the using of 36 and 21
concentrating lens of 1.122% and 1.016%, and without using a concentrating lens
the collector efficiency is obtained 0.775%.
