现在,不少人家用上了煤气灶(包括液化石油汽)。使用煤气要根据各户实际需要,合理地调节煤气灶火焰的大小.一般来说,用24厘米的铝壶烧开水时.用小火比开大火能节约煤气70%.原因是,开大火时火焰会窜到壶的外面,造成不必要的浪费.当然,也不是火越小越好,或开小火都好,而是要根据炒、爆、煨、炖等不同情况,合理地调节火焰.如果需要热水洗脸,那就应需要多热烧多热,千万不要烧成开水以后再对冷水,掺成温水.因为水在80℃以上汽化得多,消耗的汽化热也多.
Now, many people use gas stoves (including liquefied petroleum gas). The use of gas according to the actual needs of households, reasonable to adjust the size of the gas stove flame.Generally speaking, with 24 cm aluminum kettle to boil water.With a small fire than open a large fire can save 70% of the gas because the fire Of course, the fire is not as small as possible, or open a small fire are good, but according to speculation, explosion, simmer, stew and other different circumstances, reasonable regulation of the flame If you need hot water to wash your face, then you should need to burn more hot, do not boil water later on the cold water, mixed into warm water .Because the water vaporization at 80 ℃ above, consume more heat of vaporization.
