酒精燃烧值的实测[0]

Posted on 2023年11月14日 by

闲来无事,在买完咖啡一套的制作器具的情况下,也拥有了户外整套用具,想着就测试了一下酒精的燃烧值。

  • 实验器具:
  1. 爱路客的围雪炉
  2. 爱路客1L烧水壶
  3. 汽化酒精炉
  4. 98°酒精
  • 试验数据:
  1. 1000g的水从25.3°加热到98.5°,加热到98.5°时的净重减少12g为蒸发掉的水
  2. 耗时15min
  3. 消耗酒精燃料30g
  • 计算验证

1)水接收到的热量:

W=4.2×10³ J/(kg℃)*73.2=307.4KJ

2)酒精燃烧产生的热量

W=29.7*10^6*0.03/1000*0.98=873KJ

3)总效率:

P=35%

  • 其他补充
  1. 气化酒精炉容量为80g水/80mL
  2. 按照燃烧时间计算,加满酒精的酒精炉能够燃烧40min,即酒精2g/min(不可调节)
  3. 汽化酒精炉的功率为873KJ/15/60=0.97KW
  4. 17元一桶,2L,重量1.6Kg,能将0°加热到100°的水,1600/(30/0.732)=39L
