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.
