Hi all , could you take a look at this Picture , it's of my cooker when we were on holiday last week , you can just make out the orange flame tips , does anyone know what causes the tips to go orange . The gas bottle was about half full , and it was early morning , inside the caravan was a little cold , could the cold be the reason for the orange tips ? Note the flame tips were not yellow .
If the orange flame is coming from all the outlets in the ring, then there is something inside the ring causing this.
If the orange flame is happening when any of the rings are in use, then it is something in the gas.
It the orange flames are only coming from certain outlets in one ring, then dirt/food particles/whatever have somehow got into the outlets. Possible when someone wiped the stove down with a less than clean cloth.
I would certainly check these out before I went to the expense of calling out an engineer.
Thinking back to the old bunsen burners at school. We adjusted the air until the flame was blue. When it was the ratio of gas to oxygen was just right.
With a cooker, the oxygen at the top of the flame could well be less than at the bottom,.as the air is rising up from the bottom of the flame to the top. I would expect it to be a little orange.
When you put a pan on top, the gas will spread out and form a lower flame height. This will mean there is less oxygen depletion at the top of the flame, in which case it will be blue.
This may be a load of rubbish a I'm an electrical engineer, not a gas engineer.
wizard asking for advice,well i never, good on you wizard.l.o.l.
------------- its easy enough to be pleasant when the world rolls along like a song.but a man is worth while if he can smile when every thing goes f------ wrong.
As Nawer said think back to the Bunsen burner, when you close the air off the flame turns too yellow, increase air to gas ratio and the flame returns to blue, the pipe that supplies the gas has a large vent hole to draw air in and insects just love a warm place to cocoon or lay eggs, chances are there in there having a party.
The answer is to use a thin tube taped to the end of a vacuum and clear the pipes out.
There is a distinct difference between orange and yellow? yellow is incomplete combustion and orange flecks are dust being burnt in an otherwise good flame.
Yellow is normally constant and orange more intermittent as dust is disturbed.
Cold may well have something to do with it, this cools the flame and prevents it fully burning all the gas. So if the burner, (flame spreader to give it it's correct name), is very cold the flame may not be ideal until the burner warms up
A simply test is to place a preferably white pan over the flame and see if you get soot marks, no soot no problem, if though you get soot marks something is amiss
