Selubung Radiasi Untuk Efisiensi Penggunaan Energi Pada Kompor Gas

Abstract

Stove cover is a device to reduce radiation and convection heat transfer processes in a gas stove. In a condition of energy crisis recently and along with government program in oil (BBM) conversion into gas (BBG) initially in 2007, therefore an effort to conserve energy relating to BBG is needed to be performed.The aim of this research is to investigate the influence of material cover to the efficiency of conventional gas stove. Using three different materials of ceramic, aluminum and iron, the efficiency of conventional gas stove was analysed by measuring combustion energy produced by LPG, cover surface and water temperature used for cooking procces. The results showed that ceramic is the effective material as stove cover compared to aluminum or iron because ceramic have a specific heat and thermal conductivity lower than aluminum or iron. Using ceramic cover, the efficiency of conventional gas stove was increased of 2.6% to the highest efficiency of 46,6% compared to previous gas stove without cover. Ceramic cover also indicated a good characteristic for covering heat release at the initialy cooking process.
