How To Make New Gas Cooker Burn Properly?

[thaibeachlovers]

Bought a new double burner cooker and the small outlets in the center of the burners won't burn cleanly- red flame on both burners.

I have tried adjusting the air inlet under the housing, and while I can get the outer ring to burn clean, the center outlet will not respond fully.

The removeable brass cap is not blocked at all.

The instructions say only to use the correct type of gas, but so far as I'm aware, there is only one type of gas available from the gas bottle shops, and it burned fine in the previous cooker.

Any ideas?

Thanks for any help.

Take it back.

Take it back.

Unfortunately it's easier to clean the soot off the pot bottom, than it is to take it back.

So long as it makes heat, it's staying.

Had a similar problem with our twin burner.

Had to replace the regulator.

Thanks for that. I'll get onto it asap.

Yes, the regulator that I replaced was the one that came with the stove.

Was told that it was a very cheap one.

Red flame? I've never seen that before, only blue or yellow.

If the regulator allows too high a pressure for your burner, you will see the flame try to lift off of the burner and will often go out when you turn it to the lowest setting. Check out a few neighbours and see if they have different regulators to you and test, you may find out what to buy then.

sounds like the regulator ie you are getting too low a pressure...

Most regulators have a screw adjustment usually under a plastic cap to modify its pressure up or down a little. Might want to give that a try.

Been a while since I checked this, so thanks for the recent answers.

Tried to take it back, or at least get the shop to collect it, but they reneged on the agreement- what a surprise, so waiting till we get someone with a car to take it for us.

I did try buying a new regulator too, but the gas guy wouldn't sell me one. When I get near a decent gas shop, i'll try again.

I'll have a look when I get home, thanks.

It's probably more orange than red, but not yellow. It's just not combusting properly, due to ? too little O2 mixing with the gas.

It will be a "reducing" flame ie too much hydrocarbon nor enough oxygen....ie the fuel to air mix is wrong....the bluer the flame the more oxygen and eventually you end up with an "oxidizing flame"

Whenever you have a yellow flame and are unable to correct it with the airflow baffles, you really should have it checked by a competent person.

A yellow flame will deposit soot on your pan and this means that carbon monoxide is being given off instead of carbon dioxide. Carbon monoxide can kill you!

Not only that, when a flame is not getting enough oxygen, it will actively seek out more, it will flatten out to take oxygen from the outside edge of the pan. If the pan is too large for the burner, the flame can actually turn upside down. Bear in mind that many stoves in Thailand have a tray underneath that catches oil and grease spills, often not cleaned regularly. In extreme circumstances, this grease reservoir can ignite.

Thank you all.

Although the flame is not perfect, there is minimal soot on the pan bottoms. Monoxide is not a problem as it's a real Thai kitchen with basically no walls to speak of.

I tried adjusting the regulator, but had minimal improvement. I think it's a dud design, but will try a new regulator when I get the chance.
