Gas Log Flame Fires: Fill & Download for Free

Unless you have electronic ignition, there is a pilot light. That is a small blue flame that stays lit so that when you turn on the gas for the gas logs, there will be something to ignite the gas.

Because the people in that video are not very clever……and they have also — obviously — never made a…Snow lantern (image source)The website is chemtrail conspiracy nonsense so we can dismiss it for that alone.But — for anyone wondering — how come the candle is not instantly tuning the snowball into melted water?The reason is that the flame has very little heat. It is a tiny flame, against half a pound of frozen water, that is to say ice.“What are you talking about, a flame is very hot!”Yes, it has a high temperature, but since a flame is burning gas, it gives out very little heat. Because heat is not just temperature, but temperature multiplied with the heat capacity. A big snowball has a huge heat capacity, compared to a tiny little gas flame. The difference in volume alone puts it at 1/100 – 1/1000 of the snowball, and the density of the flame compared to water is another 1/1000.So during the short time they are holding the snow over that little flame, the flame simply does not give out enough heat to raise the temperature of the ice to melting.If you doubt it, put a cup of tap-water in the fridge and freeze it, then hold that lump of ice over a little flame, and be underwhelmed about the effect the flame has on the ice.Lastly, what little melting that does take place, will wick up into the snow and not be visible until there is enough liquid water to soak the snow completely and start dripping.“What about the burning snowball on the log?”They are dousing it in lighter fluid, the lighter fluid is burning. And while doing so it — paradoxically — protects the snow.“What? How is the lighter fluid protecting the snow?! It is on fire!”Because it is not the lighter fluid that is burning, it is the vapours that combust and form a flame. Before any fluid can burn it must be turned to vapour. And lighter fluid vaporises much more easily than ice, so the lighter fluid “hogs” the incoming heat from the flame (evaporative cooling)The vapours then expand rapidly away from the snow, before reaching the oxygen of the atmosphere, mixing and combusting. But in doing so, the vapours are pushing the burning hot flames away from the snow, forming a boundary layer of “cold” (compared to the flame) gas, further protecting the snow from the flames.This is the same principle used in ablative heat shields for spacecraft (which is why China could make a heat shield made of red cedar wood) and why candle wicks do not burn up (until the wick bends and ends up in the hot part of the flame).“What about the soot?”That is the paraffin wax of the candle burning poorly. The presence of a large cold body — that chills the paraffin vapours — causes them to burn sooty.

No, a purpose-built gas fireplace is NOT safe to use with a wood fire.There would be great danger of catching your home on fire.The gas logs in a gas fireplace are a very controlled flame in a very specific spot.
