Ash-based thermal insulator for solar cookers - A case study from Ayacucho, Peru
Abstract
The aim of this paper is to present an ecological, sustainable option for thermal insulator bricks to be used mainly in solar cookers. The bricks were prepared using ash produced in rural cookers in the Ayacucho region, a gel extracted from prickly pear cladodes and hydrogen peroxide. The crystal characterization of the ash was performed by XRD, resulting that calcite is the main component. Thermal characterization of the ash-based thermal insulators gave values in the interval (0.042 - 0.063) W.m-1.K,-1 results comparable with that of commercial thermal materials.
