Default Keggle taking forever to heat... ideas?

Hello everyone, I have a keggle and it is taking a very long time to heat up. It takes about 45 minutes to heat to mash temp, and over one hour to heat to sparge or boil. I have a banjo burner and a standard 15.5 gal keggle. I also adjust the air intake to the smallest opening, which seems to get rid of the yellow flame as much as possible. I set it to a level where the hiss is barely audible.

One thing I do not do is use a lid, should I?

Also, I am not turning the propane flow high enough? I used to have it roaring, but I would only get 2.5-3 (5 gallon) batches per propane tank that way. Now I can usually get 4-5, but brewing takes about 6 hours on a good day due to the excessive heating times.

I've also attached pictures of my setup, maybe there is some glaring problem. As you can see I welded brackets onto my burner to stabilize the keggle.

I have a mediocre burner that I modified in the same way as yours. It also had issues with my keggle, so I use my smaller 11 gallon Bayou kettle. I might be wrong, but that doesn't look like a banjo burner. I believe banjo's have a larger burner with more BTU's.

Anyway, what I did was make an insulation jacket for my keggle out of Reflectix . It only went about 2/3 of the way down the side of the kettle from the top down, since the lower section is too hot and will melt the insulation. It seemed to help retain heat, but it was only a Band-Aid fix.

You can use the lid for heating water and bringing wort up to a boil, but you'll want to remove it when the boil begins.

In the end we both need better burners.

Correct me if I'm wrong, but more fuel --> bigger fire --> more heat --> less boil time.

He mentioned that he tried that, but it wastes too much propane.

In my case, my burner has a safety switch that will shut the burner off if it gets too hot. Every time I try to boil in my keggle I have to crank up the heat, but it always trips the safety switch. My smaller kettle doesn't require as much heat, so it doesn't trip it. When I did get the keggle to actually boil it was only a gentle boil, so I gave up on it. A new burner is on my wish list for this year...

Well as you said, you either stick a band-aid on it, bite the fuel bullet, or upgrade. Personally I'd fork over the extra propane costs to cut 2 hours off my brewday, but to each their own.

Good luck bud!

How many btu's is your banjo?

I can heat my keggle up to mash temps in about 10'-15' if I open the burner up. I think it's 150K btu.

the SP-10 is air starved with a keggle. the add-on tabs make it fit, but there is only 6 1" tall exhaust vents, and it has to vent DOWN. it just can't breath.
its not the burner or the BTU's its the frame/vessel combo.
just wasting propane.


its a cup burner, not a banjo

Do they really call that wee little thing a "banjo burner"? It looks like an infant compared to one of these 10" beasts...

Now that's a banjo burner!

Cheers!

Oh... You are right, it's a sp10 bayou burner, not a banjo burner. Thanks for the input guys. Amandabab, what if I just raised the spot where the keggle sits up an inch? Would that improve things?

Here is another pic... You can see it does seem to have a gap there.

I actually considered raising the burner on mine to get it closer to the bottom of the kettle, since the keg bottom sits higher up.
