This study was conducted an experiment for the thermal flow mechanism of the surrounding butane gas can and pressure change in butane can with oversized cookware. And numerical analysis was performed to analyze the process of heat transfer around butane can. Effect of radiant heat from small size cookware is very small. Thus small size cookware does not have a significant impact on the butane gas range safety. But radiant heat of oversized cookware is larger than small size cookware. Therefore it gives an adverse effect on the butane can. And when internal pressure of butane can is greater than about 406.8~447.2 kPa, a safety device of portable butane gas range were working. The causes of safety device working is because of trivet height. Trivet height is lowered, the radiant heat is increased. This radiant heat is to raise pressure of inside butane can. Experimental and numerical analysis results, the lower thermal conductivity of the cookware is greater the effects of radiant heat.
