Through the economic development, people enjoying the camping and demand of camping goods are increasing since they have free time. So they use portable butane gas range outdoor. In addition to that, many restaurants that offer hotpot or meat in Korea use portable butane gas ranges for their convenience. But 19% of gas accidents are using portable butane gas range, 13.7% of them are using oversized cookware. Despite the high accident rate, there is no safety standards about portable butane gas range using oversized cookware. Therefore we conducted to measure temperature and pressure of portable butane gas ranges for reforming safety standards. As a result. we confirmed relation between bottom temperature of the portable butane gas barrel and pressure of the butane gas. Also we confirmed that portable butane gas ranges operate safely when bottom temperature of the portable butane gas barrel is bellow $50^{\circ}C$.

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.

The experiment was conducted to measure temperature and pressure around operating portable butane gas ranges with oversized cookwares. In this experiment, portable butane gas range with different safety equipment and two kinds of oversized cookware, each of which is made of aluminum alloy and rock, was used. As a result, temperature of the bottom of the butane and the pressure of butane barrel tend to aligned with each other. Through this result, it is reasonable that a safety criteria can be decided based on the temperature of the bottom of butane. Especially, portable butane gas ranges are safely conducted under the condition of the temperature is under 50 degree and pressure is under 500 kPa, respectively, at the bottom of the butane barrel.
