Rather than having the gas spread out by the burner cover like this:
I would like to have one central flame. Can I do this by removing both the burner cover and the burner itself leaving this:
Firstly, would this even burn as there isn't an air inlet like the burner has. Secondly is it safe?
The reason for doing this is because I have a small radius coffee maker:
The burner and gas orifice are configured to give a proper air-fuel mixture so the appliance can safely be used to burn the gas completely into carbon dioxide and water.
With the burner removed, you won't even have the equivalent of a good propane torch or lab Etna and with an improper air-fuel mixture, soot and carbon monoxide can be part of the resultant combustion output.
Your main problem is that you're trying to use a camp stove/hiking coffee maker on a kitchen range.
This device is sized for use with alcohol stoves, butane burners, their propane canister kin or propane camp stoves which all have a small burner diameter.
The best bet would be a sort of conical chimney that sits over the kitchen range burner on top of the grate and funnels the heat up to a smaller grate that your coffee maker sits on. If you look through the various online camping forums, you might find someone already makes these.
If the problem is using a small coffee maker on a gas burner for which the supports are too far apart, there is a product for that:
Supposedly called a "stove hob reducer".
I've seen them being sold in the spare parts stores.
