In this study, the thermal efficiency of a conventional kerosene pressure stove equipped with porous radiant inserts have been investigated. Four different porous materials, viz., silicon carbide (SiC), zirconia (ZrO2), wire mesh roll filled with metal balls and alumina (Al2O3) have been used as porous radiant inserts. The inserts have been found to increase the efficiency of the conventional stove from 55% to 62%. SiC insert exhibited the highest efficiency (62%). Additionally, the flow rate and the vessel size have been optimized for the best thermal efficiency.
