Abstract

Abstract A mosaic solar furnace has been fabricated with locally available materials at a cost of about 5000 rupees. The concentrator has a power input of about 6 kW. The efficiency is upto 40% at low temperatures but drops at elevated temperatures. The reflecting surface is made of about 10,000 2.5-cm 2 commercial back-silvered, plane glass pieces and is approximately contoured to a paraboloid. The furnace recorded a maximum temperature of 520 °C at the focus and had a sharp temperature distribution at the focal region. Suitability and economic viability of this furnace for energy uses are discussed.
