hi-just bought a trigano trailer tent,tried cooking on it,but the hobs are burning with a sooty yellow flame,one is really small flame,the grill works fine,i have stripped and cleaned it.i have been advised to swap to calor gas,is this butane?? i can only use propane or butane ps tent was second hand,person i bought it from says all ok when used in may any ides please??
Butane shouldn't burn with a yellow flame, the cause of this will be lack of oxygen, the burner should mix oygen with the gas before it burns, like a bunsen burner.
It would be good to know what the stove is, questions you should be asking are...
Have you blocked an air intake in your positioning of the stove? Have you reassembled the burners correctly? Are the burners blocked?
The fact that the grill works fine suggests that one of the above is the issue. It may be that in your stripping you've managed to drop crud from the burners down into the gas piping.
Suggesting you should switch to calor gas is like saying PB petrol will fix your knackered car. Calor sells cylinders of butane and propane in the same way that BP sells Petrol and Diesel.
In the meantime be careful about fumes. A yellow flame (as opposed to the normal blue flame) indicates a rich mixture (usually due to lack of air) and potentially lethal carbon monoxide may be given off, using it in an enclosed space is not advised. Try taking it up with the manufacturer (after checking instructions), even if it is 2nd hand they might do something due to the serious implications. Is it CE certified?
I bought a second-hand cooker and even though there was gas coming through to the burner it had a yellow flame. I had to really 'scrub' at the insides of the burners to get them properly clear. Once that was done the nice blue flame was there. A small bit of grunge in the pipe will cause enough of a blockage to change the gas/air ratio. You might also get some blowback and have the gas ignite just behind the tap and have flames going up your pipes to the burner. Definitley not to be recommended!!!
Changing to Calor Gas will not make any difference. Calor Gas is a brand name like Alta Gas, Shell Gas, British Gas etc. and like all the other suppliers they supply both propane & butane gas cylinders. Changing from butane to propane or vice versa will probably make no difference.

In two thirds of cases,it will be down to burner airways being clogged preventing proper combustion of the gas causing yellow tipping of the burnerflames and possible sooting on pans,kettles etc with a gutless heat and possible gassy smell. If you have an old calor gas cooker and you are experiencing yellow tips with possible soot,then the burner airways could be full of rustflakes ie burner cap/assembly disintegration and there is no cure for this other than complete replacement and refitting of brand new burners and burner assemblies:if you do manage to get spare parts for your cooker(and it might be hard because many older ones particularly the flavel calor gas B500-B700 cookers and flavel tina/vanessa cookers and the stoves/newhome calor exclusive cookers are no longer produced,then get a calor dealer equipped to service cookers,indicated on the calor website by a pan symbol with spanner to do this for you. dont do it yourself-go to www.calor.co.uk to locate your nearest main dealer to do this for you). If you have a newer cooker,then it may just be the burner airways and pipes which need cleaning. However even after cleaning,you may still find you still find that you get very slight sootless yellow tips at the top of the burnerflames when using butane:this is quite normal and nothing to worry about when using butane,but will be completely blue with propane,perhaps with a very slight yellow tip to the flame on grill and oven burners of a caravan cooker,and same on waterheater pilots(this does happen on propane gas),but again this is nothing serious to worry about.

Propane uses 5 molecules of oxygen per molecule of fuel for complete combustion. Butane needs 6 and a half molecules of oxygen.
If there isn't enough oxygen you get yellow flames, and carbon monoxide/carbon (soot) produced.
A mix with a higher proportion of propane will be more likely to burn with a blue flame. Make sure all airways etc are properly clear & that it is well ventillated.
