Topic: Increase the Btu of your domestic gas cooker

Here's a few links for anyone wanting a bigger flame at home.

Increase power of gas range
Ok, so I need some more power out of my current gas stovetop. Is it possible (i.e SAFE) to increase the power of the burners. I need to bring ~8 to 11 gallons of water to a boil on my stove top. My old range, at my old place, did this without issue. The range at my new place barley gets 7.5 gallons going. Do I just need to clean the burners or can I get some replacements. Thanks


Welcome sideshowdave to the Gas Appliances topic and the Do-It-Yourself Web Site.
What you would like is larger flames. You're likely to get them but may not be as easy as an adjustment. But lets try it. Turn the brass or bronze orifice nut clockwise as you look down onto it.
The orifice is the hexagon nut the back end of the burner sits on. It's screwed onto the gas valve that you use to turn the burner on. Use a 7/16th inch open ended wrench to turn the nut.
Give the orifice nut about three to four turns clockwise as you are looking down onto it. Than turn the burner on and note if the flames are slightly larger. They may or may not be.
If the flames are larger by any noticeable amount, the orifice is adjustable. If not, may have to turn the orifice another 2-3 turns. Flames cannot be too large or the fuel will not completely burn. Soot and odors will be produced.
If the flames do not increase in size, the orifice(s) are non adjustable. Larger btu orifices will need to be purchased. Note the existing btu for the burner you want to increase the flame size on.
One BTU rating size up in is all that a burner should be increased to, above the current btu amount or the flames will be yellowed, create soot and odors, plus carbon monoxides.

Rough Example:
Current burner btu rating of 8,000. Max increase to 10,000.
Post back the current burner btu rating. I'll help you size it one size up.

and another excerpt:
Unscrew the little brass jet tip and drill the 1/16th hole to 5/64th. Replace and that burner is now converted from 16,000 BTU's to 20,000 or 22,000 BTU's.
Safe and easy. I did it to my Wolf stove years ago and finally got around to doing it to my Rangetop. The low, simmer and medium settings still work just fine, but you'll get big juice on high.

That was a very interesting read DP! Are you going to apply these ideas?

I'd be a tiny bit afraid of doing something wrong and causing a fire and/or explosion by going the DIY route.

IF i had gas here, i would do this in an instant! But sadly, no gas in my village even though everyone wants it and the main pipeline is running straight through. 

When the weather warms up, i'll be back outside under the porch with my wok burner. Until then, i'm stuck with a poxy old electric cooker.

Just connect your existing cooker across any two phases of a 3-phase supply and you'll easily outdo those pathetic 10,5kW gas burners for heat output
