Help! All my burners make soot!

[CanadianQuaffer]

Hey everybody,

I have two propane cookers, the style of the burner is shown in the link below, the difference being mine are generic 60,000BTU burners, not Bayou Classic 150,000 burners.

BG-10 High Pressure Cast Iron Burner

The problem is both of them create a lot of soot on the bottom of my pots. I've tried playing with the air/gas mixture to no avail. Is that just something this style of burner is prone to? I don't wanna have to clean this black crud off the bottom of my pots everytime I brew.

Is there something I can do or should I just buy better burners?

Thanks!

Nick

Are you running both burners simultaneously off the same propane source? Is this a new problem or have they always done this? I'd check inside each burner for spiderwebs, casting slag, etc.

First question, without a pot on the stand can you get the burner to burn clean (blue flame). Second question is distance from top of burner to bottom of the pot, needs to be so light blue flame center does not touch bottom of the pot.
The fire needs additional air for combustion over the air coming through the air shutter, if insufficient air can reach burner because of to tight fitting heat shield then it is soot city. The second most common problem is called flame quench when inner flame hits something cooler and combustion is interrupted leaving a lot of carbon and carbon monoxide running loose. It is okay for the darker blue outer flame to touch metal pot bottom, just not light blue inner flame.

Both burners are brand new, and I run them off the same propane tank, but not at the same time. (one for the HLT, the other for the BK) I've used them only once each and got this problem right away.

Without a pot on the stand I can get a clean blue flame with small yellow tips. Once I put a pot on the flame it runs along the bottom of the pot and curls up the sides for about 1". That's where/when the flames get really yellow and create lots of soot.

This is actually the model of cooker that I have, in case that helps.

The difference in the BTU is 2 items, orifice size and fuel pressure. What type of regulator are you using? Is it adjustable? What is the maximum pressure. I would agree with kladue except there appears to be a decent gap above the ring and these are designed to be used with a pot.

The regulator is 10 PSI and is adjustable.

Do you have enough space between your pot and stand to vent the combustion gases? I had a similar issue on my stand using a 6" NG burner from agrisupply.com; blue flames without the pot and weak yellow flames with the pot. I welded on some pieces of 1/2" diameter rod to elevate the pot slightly and that solved the problem. Maybe try inserting some kind of temporary spacer between the pot and the stand to see if that helps.
