Abstract:

Attempts to study the effect of blend MnO₂ and PANI-MnO₂ nanocomposites in enhancing the productivity of an acrylic Pyramid Solar Still (PSS) is carried out. Synthesized nanocomposites assorted with black paint to improve the absorption efficiency. Size of the synthesized MnO₂ is found to be 35nm. SEM image infers particles are aggregates with random shape. Thermal analysis if distillate yield confirms the formation of nanocomposite with improved thermal stability of the PANI. Distillate yield is observed around 0.484 litre/0.25m², 0.568 litre/0.25m² and 0.615 litre/0.25m² still without and with MnO₂ and PANI-MnO₂ nanocomposites. Average efficiency is found to be 23.05%, 26.63% and 28.52% under three modes. Efficiency of the combined performance is amended due to the absorption properties of MnO₂ and PANI-MnO₂. Performance ratio under three modes are found to be 5.52 %, 6.44 % and 6.93 %. Results concluded that saturation vapour pressure and latent heat also plays a major hole in production of distillate yield.
