Topic: BBQ Burner Heat Control (15 msgs / 616 lines)
1) From: Justin Marquez
Just ordered this from a cajun-cooking place:http://www.cajun-outdoor-cooking.com/sepasttecova.htmlName                       Code           Qty   Each  Options
Sentry Patio Stove         SCB001-1         1  24.99
Temperature Control Valve
It has a temp probe that would normally drop in the oil in a "Cajun
turkey fryer" and control the burner feed to keep the oil from
overheating.  I will see if it can be used, or modified, to control a
burner to hold air temp in a BBQ grill.

Let us know how it works out. I am definately interested in this

Me too - these temp controllers may be EXACTLY what I need to gain precision
over the BBQ...

I am already thinking through the modification of my drum to enable temp
probe insertion while the drum operates on the spit...  I am looking forward
to hearing how the temp control performs...

I may have missed your report on how this product worked in your BBQ Grill.
Did you find it useful?

I must have missed your post on the subject.  Did you use the product as a
replacement Gas Grill burner control for a Grill coffee-roaster setup or for
normal cooking?  If for coffee roasting, how's it working for you versus the
default gas control that comes with a typical grill?  I'm at the point where
I need to replace my burners (again) and I'd like to find a better
valve/control product if possible as well.  I've got a lot of "play" in my
old valves and they are getting hard to adjust.  I'm also interested in a
product that could adjust gas flow based upon a set point for desired
Lately, I've been attempting to control the wind effect upon my grill by
covering holes and certain areas, but haven't had total success.  By it's
design, a gas grill has to allow for some air intake and hot air exhaust but
that also allows for wind to have some fun with my temps at times.  It's
really only a problem when there's a stiff wind and air temps are colder as
I'm sure most grill-roasters have found.

Haven't messed with it yet - too much else going on in my life right now.
One thing I have noticed is that it may be tricky to connect in on my
BBQ with all the burners it has.  The device looks like it would be
really easy for a single burner hook up but not so easy for multiple
burners. When I do get around to messing with it, I will scan the
instructions that come with it and take close-up shots of the
connections so y'all can see what I am discussing.
At first glance, it appears they slip it onto the burner assembly not
into the supply line as such.  I just haven't really dug into it yet.

No shame, just thought I'd check back with you.
I've seen that some of the gas-smoker-BBQ folks are using this device to
control temps in their gas smokers.  They claim that it maintains temps to
within 5F of the basic settings.  
The device appears to have a 450F max temp setting.  I can easily see where
this device would be useful for either turkey-fryer oil temp control or for
a gas-smoker BBQ.  In those environments, a 450 max temp control is plenty.
For coffee roasting, 450F in a gas-grill is too low from my experience.  So,
I'm guessing that the device would not allow full flow of gas and thereby we
couldn't get high enough temps for coffee roasting.  I've done a little
research into a PID solution and just the PID managed gas-control valves are
quite pricey ($300-$400).  Then you would have the cost of the PID in
addition to the valve.
Seems there is no easy, low-cost answer yet, but I'd sure like to find one.

There are different temperature areas inside a grill.  Find a cooler area and you will be able to attain 
the higher temperature at the beans and still have control.  Each grill design will be different so 
individual experimentation will be required.  It is also possible that the "device" can be modified to 
attain a higher temperature control point.  I do not have one, so I do not know the answer in this case.

I agree with you... careful placement of their supplied temp probe
would probably allow for 500 degrees temp at the area where the drum
is located.
The thing appears pretty well sealed up, so modification and
reassembly might be tricky.

While this thread is active, here's something else I ran across over at
Omega.http://www.omega.com/ppt/pptsc.asp?ref101&Nav=grej10It's a proportional valve that I think can be PID controlled.  I'm not
suggesting the average person would spend the bucks for it, just offer it as
something I saw.  I was reading the specs on it and it has a control range
of 15-85% of full flow.  Not owning one of these PID controlled devices, I
was left with some questions about how they really work.  For instance, can
you still open it up 100% for max gas flow and then vary it within that
15-18% range, or is the range all you ever get?  I'm not an Engineer, but do
find this stuff interesting as I ponder the ways to add some temperature
control to my gas-grill (other than the wind and my fingers).

You size the valve for 100% of the flow you require at the 85% open point of the valve.  There are much 
cheaper alternatives.  The PID can be had off of the nations garage / junk sale site...  Valve also

Agree...too pricey on that valve for my interest, but I also didn't know
such a thing existed.  Thanks for the answer on the way it works.
