Abstract

New attempts have been made to study the spectral properties of ash for use as a solar selective coating. Ash coating has been added as a better efficient coating to the other commercially available coatings. Investigations have been made to study the reflectance properties of ash coating. The reflectance of the ash coating was compared with that of other two coatings namely black chrome and black nickel. Ordinary painting method has been adopted as the coating technique. Aluminium absorber has been used which was coated with colloidal ash and was allowed to dry. Water heating test has been carried out to study the optical efficiency of ash on Aluminium vessel. For solar thermal applications, this coating has been proved to be one of the best solar selective coating with maximum optical efficiency.
