Is this in a continuous kiln?

I suspect the silicon baffles would work well.  Check them with the fans on to make sure they are not lifting due to the air pressure.
In a conventional kiln (noncontinuous) a difficult spot is where the bottom or top baffle meets the end baffle.  Make sure you get complete closure in those corners.

Please keep us posted on your results.

General Discussion / Different Types of Kiln baffling.
« Last post by JedLagoy30 on March 07, 2019, 06:58:20 AM »
Hi everyone, I'm kind of new to all this kiln drying stuff and I wanted to pick everyone's brain on kiln baffling types. We use Stainless Steel baffles, and in the top of our kiln we have brush and high temp rubber baffling. All this seems to hold up pretty well considering. What other types of baffles are available? Has anyone tried any new kind of baffle systems in the recent years? I've recently acquired some samples from another company working on a cheaper solution to baffling "High Temp Silicone" baffling which is super cheap and flexible has anyone tried this yet? I planned on putting some of these samples in my kiln after this coming shutdown to see how it would hold up in the heat. These samples will be in there for 3 to 4 months before we get a chance to look at them again. This all applies to floor baffling and door baffling as well. I think that a high temp silicon/rubber material would hold the heat better and be more flexible to incoming and outgoing packages then stainless steel or a metal material.

Standard deviations and average mc's are all good markers for change, yet in the end the highest average mc you will be able to attain will be governed by what percentage of your volume you will allow to be over your maximum allowable mc. If you allow 10% to be above the max that will allow a higher average mc than if you allow 5%, and that will allow more than if you allow 0%.

One thing though....if you, for example, will allow 10% of your volume to be over 19% (assuming for this example that is what you stamp your lumber), then if all 10% lies between 19% and say 22% that will mean one thing versus if the 10% volume lies between 19% and 26% that will mean another.

Just another way to view things. Good luck.

I can't comment on the emissions from a direct-fire kiln.  I will say that the MACT regulations are implemented at the state level.  Any direct-fired continuous kiln is likely to be in the Southern U.S.  Their regulators may have a different take on the subject than regulators in your state (I'm assuming you're in the West when I say that).  Please let us know what you find out.

General Discussion / sawdust fueled direct fired continuous dry kilns
« Last post by Craig Jensen on January 09, 2019, 01:57:17 PM »
Anyone here have experience with sawdust fueled direct fired continuous dry kilns for softwoods?   I have been asked by my superiors about them, and all I have is a basic theoretical understanding.  No actual experience with the concept.   

Looking for pros, cons, advantages, disadvantages, and things a newbie might not expect.

Has anyone installed them in the current MACT environment and if so, any ideas on the emissions side?

Thanks in advance.

RTO - Regenerative Thermal Oxidizer.
I have not heard of any on kilns.  The capital cost for an RTO would be more than that of the kiln and consume lots of energy.  It heats the exhaust air to about 1600F to change all organics to CO2 and H2O.  Some of the energy is recovered (regenerative), but they are still large consumers of natural gas.  To use one you must capture all the exhaust gas meaning ductwork in kiln or to all vents. They are common on board presses and some veneer and particle dryers.
