Using big pots on portable stoves may cause gas explosion
Using big pots on portable stoves may cause gas explosion
2026-01-30
With the recent cold weather, many people have been enjoying hot pot in the comfort of their own homes using portable gas stoves. But first responders said they have recently seen patients with injuries from these stoves exploding. Wanting to cook more food faster, they used a pot too big for the stove, heating up the gas canister on the side and causing it to explode.
Taiwanese actor Ming Dao warns of the dangers of using portable gas stoves. Many people use small stoves like this to cook hot pot at home, but it’s important not to heat up the gas canister on the side.
Firefighters described these portable stoves as “grenades on the table.” They said people had recently been injured with metal shrapnel from one of them. Wanting to cook more food at once, a group of young people used a pot too big for the small stove, causing the gas canister on the side to heat up and explode.

If the temperature exceeds 100°C, it will trigger a valve that shuts off the gas supply. But if the temperature rises too quickly and the pressure exceeds 15 kilograms per square centimeter, the safety valve will activate and start releasing gas. But if the heated surface is too large and quickly surpasses 100°C with high pressure, it doesn’t have time to relieve the pressure or shut off, and will explode.
If the pot covers the lid of the gas canister, it’s like putting the canister in the fire. When the canister’s internal pressure exceeds its limit, the gas will vaporize and expand.

When cooking, try not to use any pots that extend beyond the stove’s grate, as this can overheat the gas canister. Second, ensure proper ventilation. The canister has a ring-shaped notch that must be secured with an audible click to prevent gas from leaking.
It’s important to not use pots larger than the stove grate, not use portable stoves side by side, and stop using them immediately if the gas canister starts to warm up. Don’t let the simple joy of cooking a warm meal on a cold day turn into a disaster.

卡式爐變"餐桌手榴彈" 消防員示警:鍋具過大恐爆炸
2026-01-30
天冷不少人會用卡式爐來煮火鍋，但消防員卻示警，最近接到一組病患，不少人大腿被炸得皮開肉綻，原來，他們是用卡式爐煮火鍋時，嫌棄太慢，改用超大鍋。結果因為鍋面超過爐架，導致瓦斯罐被加熱，進而爆炸。
小心會爆炸！藝人明道在講，大家有沒有在聽！不少人都會使用卡式爐來煮個火鍋，但要小心，意外就是來得這麼突然。
消防員示警，以餐桌上的手榴彈，形容卡式爐。貼文寫下，急診室收到一些病患，大腿被金屬碎片炸得皮開肉綻。原來，這群年輕人，嫌小鍋子不夠吃，拿出大鐵鍋，放在小小卡式爐上，結果就是無預警的爆炸。

“如果溫度達到100多度的時候，它會造成裡面有一個瓦斯遮斷閥，它就會遮斷，可是如果你的溫度來得很快，它會每平方公分超過15公斤的時候，它安全閥就會啟動，開始會洩瓦斯囉，但是由於你的爐面太大，一下就超過100多度，壓力也很高的時後，它來不及卸壓或遮斷，它就爆炸了”
鍋面蓋住瓦斯罐艙蓋，就像把瓦斯罐丟火裡烤，內部壓力飆升，超過極限，液態瓦斯就會瞬間汽化膨脹。

“烹煮的時候，爐具的部分盡量不要使用超過爐架面積，會造成加熱瓦斯罐的一個狀況，第二個部分就是要保持通風，(瓦斯罐上有)一個環狀缺口，它會要扣上，而且要有聲響這個動作，才不會有瓦斯外洩”
專家提醒，鍋具邊界不過界、別並排使用卡式爐，瓦斯罐溫溫的就要立即停用，別讓冷冷的天，來上一鍋的小確幸，變了調。
