酒精燃料和丁烷燃料的综合对比[0]

Posted on 2023年11月14日 by

对于酒精炉和气罐的燃烧值对比见以下两篇:

  1. 酒精燃烧值的实测
  2. 丁烷气体燃烧值实测

酒精:

  1. 17元一桶,2L,重量1.6Kg,能将0°加热到100°的水,1600/(30/0.732)=39L
  2. 效率P=35%

丁烷:

  1. 450g气罐的价格35元,能将0°加热到100°的水,450/(12.6/0.668)=23.9L
  2. 效率P=46%

户外使用时,除了需要考虑燃料的易获取性,燃料的价格,还需要考虑燃料的重量。因此实际使用时的考虑变成了产生相同有效体积的热水需要的价格和需要背负的重量。

以产生1L,能够从0°加热到100°的热水为要求。重新计算。

酒精需要30g,价格0.32元,丁烷需要12.6g,价格0.98元。

欢迎回来

希望本站对你有所帮助!
