Thanks for the reply. I’ll look into the larger tank and higher flow option. I was able to get some higher flames so once the project is complete I’ll see how it looks. Thanks
I have a 36” ring using LPG 5 gal tank with low flame. The video mentions a larger ring can cause lower flame so what can I do ? It’s using an air flow mixer and a 1/2-3/4” adapter. Thanks
Hello @bargainbob4346! To get larger flames with the scenario you are explaining, you would need more gas flow at your source. The 5 Gal tank you are using, can only output, at most, 90K BTUs of gas volume. The 36" Ring size (Depending on brand) can produce up to 250K Btus. So you are spreading out the amount of gas capable on a large burner! Kinds like using a fire truck hose, hooked up to a garden hose source. What you can do is go with a larger propane tank, for more flow, 60lb-100lb tank. When you do that, you will also need to upgrade the air-mixer to a higher flow mixer or modify the current mixer to allow for more flow (But we dont recommend this in almost all cases). Hope this help! More Gas = More flame!
On a fire ring, you don't want the holes too small or too large. If they are too small, the gas will have a smaller port to burn which means smaller flame. If they are too large, the gas will escape towards the source and the flame size will diminish as the gas travels further down the burner. You want the holes to be the right size where the gas can evenly distribute to all burner ports. For this, we typically suggest around 3/16" to 1/8".
This particular LP hose is rated at 150k BTUs and has an Outlet Pressure of 11" WC. Two Stage Regulator w/ 5' Hose Flow Cap. 150K BTu/Hr Inlet: 25-250 PSIG Outlet: 11" WC, 3/8" Hose ID Inlet: Acme Nut Outlet: 3/4-16 UNF Nut
