枫下沙龙 / 户外活动 / Camping cooking 用propane和 butane作燃料，效率有区别吗？哪个更高些？

Butane is more expensive. I guess it's more efficient.

Propane三个碳，butane四个碳，碳越少含氢比例越高，燃烧放热也就越多。所以同样重量，propane应该放热多吧。

Propane is it's more like for household and park usage while butane and typically for back country outdoors activities

你说既然propane又便宜效率又高，又能低温气化，为啥不能做成小瓶子给backpacking 用呢？是不是因为propane气压高不好携带又危险？

No, the efficiency is lower, from what I read.

Butane is more efficient. At above freezing temperature, it generates 12% more heat than propane.

你指的BUTANE是不是那种扁气罐? FUEL CANISTER，其实是mix propane的，比例是80:20

Those you find in an outdoor store.

另外butane低温不气化。

两点: 任何燃气都不纯，而且根据分子碰撞，气体混合物比任何一种单独气体的沸点都低。还有，butane有同分异构，用于燃烧的一罐气里是其混合。

不懂这么专业的。就是winter camping的时候butane气罐不着火。

对的，差别在冬季户外butane不能用。

炉头很重要，要带稳压REGULATOR的，日本SOTO的掌上炉头可以用于低温高海拔地区，零下十度没问题，保持强劲火力

Propane 性价比高，但罐子较重, 就算小罐也相对沉，backcountry 用butane 较理想

The most economical way is to use white gas for backcountry camping.

My stove is for butane, so I have to stick to butane. But I'd recommend white gas since it works great in cold weather and high altitude. The drawback is the whole set of gear is bigger than butane things.

You're welcome. Another drawback of white gas is, there's a "warm-up" stage each time you start the stove. There's some black smoke during this stage, because the stove is not hot enough yet.

这个第一次知道。学习了。我准备以后用乙醇，更轻便高效。

也可以用甲醇Methyl Hydrate，我给TRANGIA酒精炉里用， 无色无味，乙醇会烧黑锅底

甲醇有毒，操作有危险。乙醇不会烧黑炉子，异丙醇会烧黑。但现在市场上很难买到乙醇了，都是甲醇和异丙醇。

对， 外面卖的消毒剂都是异丙醇，纯乙醇买不到。所以只能用甲醇，室外通风没问题

正解。我有COLEMAN DUAL FUEL 炉子和灯，用的是WHITE GAS

算了一下，propane 50.5千焦/克，butane 49.6千焦/克。而且前者便宜多了。

我的理解是，butane是在propane里面添加了防冻的物。比如冬季camping, propane会冻住，要用butane。所以butane贵一些，如果在家或者气温不下0° 用propane就好了。
