燃气热水器的“干烧”现象与防范措施
The phenomenon of "dry burning" of gas water heater and preventive measures

燃气热水器的“干烧”就是指在使用燃气热水器时,关闭了燃气热水器的进水阀后,燃器热水器的主火不能自动熄灭而继续燃烧,这种现象称为“干烧”。发生“干烧”时,由于没有新的冷水流入,热交换器(即水箱)内的水不流动,燃烧使水箱里的水烧开产生水蒸气,从而使水箱和管道的内压增大,最后会使水箱水管破裂,严重的会产生爆炸。如果附近有人,就极有可能水蒸气所灼伤。


发生“干烧”的主要原因有两个:一是燃气热水器使用一段时间后,水路系统积垢严重,水管内沉积物太多,导致燃气热水器的水动开关工作失效,即当水压降低到使用标准值以下或断流后,不能自动复位切断主气路,使燃烧器继续燃烧;二是燃气热水器内的控制电路失效,不能按程序去控制热水器,从而产生“干烧”现象。


燃气热水器“干烧”的发生主要原因一般是水质和控制部件的问题,因此,防范的措施主要是:在燃气热水器上加过热保护装置和漏压装置,在水温过高时,自动切断燃气供应,中止燃烧。水箱及管道内压超过限定值时,漏压装置自动打开减压。


Of burning gas water heater "dry burn" point to when using burning gas water heater namely, after shutting the water inlet valve of burning gas water heater, the advocate fire of burner water heater cannot be put out automatically and continue to burn, this kind of phenomenon calls "dry burn".When happening "dry burn", because do not have new cold water to flow into, the water inside heat exchanger (namely cistern) does not flow, combustion makes the water in cistern boil generation vapor, make cistern and conduit thereby inside pressure increases, can make cistern conduit ruptured finally, serious meeting produces explosion.If someone is nearby, there's a good chance the steam will burn.


"Dry" main reason has two: one is the gas water heater USES period of time after the water system fouling, sediment within the pipe is too much, lead to the water of the gas water heater switch work failure, when the water pressure drops to or below the standard values after cutoff, does not automatically reset to cut off the main gas path, make the burner continue to burn;Two it is the control circuit inside burning gas water heater fails, cannot go controlling water heater by the program, produce thereby "dry burn" the phenomenon.


Burning gas water heater "dry burn" produce main reason is the problem of water quality and control component commonly, accordingly, the measure that prevent basically is: add overheat protection device and leakage pressure device on burning gas water heater, when water temperature is exorbitant, cut off automatically burning gas supply, suspend combustion.When the pressure in the water tank and pipeline exceeds the limit value, the leakage pressure device will open automatically to reduce pressure.
