Training / Events / Kiln Drying of Hardwood Lumber Short Course
« Last post by admin on March 03, 2015, 08:55:59 AM »
Penn State Extension will be offering a 3-day Kiln Drying of Hardwood Lumber short course on June 2-4, 2015 at the Livestock Evaluation Center at 1494 West Pine Grove Rd, Pennsylvania Furnace, PA.

This three-day workshop is designed for kiln operator trainees, plant managers, and supervisors who are looking to gain knowledge in the art and science of drying hardwood lumber.  No previous drying experience or training is necessary.

The workshop will include lectures, demonstrations, and hands-on exercises.  Participants will learn about wood-moisture relations, kiln operations, drying schedule preparation, lumber handling and storage, and much more.

The cost is $350 to attend if registered by May 12th.  After May 12th the cost increases to $400.  The cost includes lunches and materials.  You may register online by visiting on the web, or by calling Penn State Extension in Forest County at 814-755-3544.  Questions can be directed to Scott Weikert at 814-755-3544 or by email at

Penn State encourages individuals with disabilities to participate in its programs and activities.  If you anticipate needing special accommodations or have questions about the physical access provided, please contact Scott Weikert at 814-755-3544 in advance of your visit.
Dry Kiln Control / Re: Kiln heating
« Last post by Craig Jensen on March 03, 2015, 08:17:27 AM »
I imagine you have to be careful with what I am about to suggest if you are drying dimension, as we are a stud mill and my experience only applies to 2x6 and smaller.

I am assuming that we are not getting to our setpoint, which means we are not really controlling our kiln - it's wide open trying to hit a high setpoint.

I am also assuming that the driving force in drying is depression.  Early in the schedule there is a lot more mass in the kiln to heat, because we have not removed the water yet, but free moisture comes out easy.

I have found that if we can't reach set point temperature, we can achieve drying as quickly by lowering the wet bulb set point a little.  This results in venting,.  However, if you have wood that is over 2/3 water by weight, sometimes releasing the water through the vents a little earlier will reduce the mass sooner in the schedule and allow you to get what you are after.  So if I have a schedule that had a tight depression early but I can't reach the dry bulb setpoint, sometimes lowering the dry bulb setpoint 5 degrees, but the wet bulb 10 degrees will allow us to hit that set point, remove the water that comes out easy, and then tighten up a little later and hit higher temperatures. 

Like I said, I know you need to be careful, as this can increase the drying defect if done too quickly.  But the driving force of drying is depression as much as temperature, so if you can't have temp, maybe you can have depression?

Just something we have played around with and found a little more success.  You have to play with it a little to get that sweet spot where you are heating up as quickly as possible.
Dry Kiln Maintenance / Coils....Horizontal or Verticle???
« Last post by GeorgeCulp on February 24, 2015, 02:09:57 PM »
I'm involved with the design of a new kiln. The customer is asking about running the reheat coils vertically instead of horizontally.

I know that fin pipe banks are normally run horizontally, but is there any good reason to not run them vertically?

I think one is kinda stuck if their kiln isn't heating fast enough. It's normally too costly to add boiler capacity and too difficult to juggle kiln startups to compensate.

If one has recently done something to increase airflow and now the kiln takes longer to heat up, then the airflow increase is the answer. Normally, when airflow increases there is an increase in heat transfer from the fin pipe, however there is also an increase in heat transfer to the wood. If there is not enough steam available to replace the increased amount transferred due to the increase in airflow then the kiln will take longer to heat up because the heat is being transferred to the wood and not staying in the air.

But what do you want? Hot wood or hot air?

A continuous kiln should save energy.  The total time for wood to be in the kiln may actually be longer, not less, but that is probably not an important consideration.  The boiler will fire at a steady rate.  This may help with its control.  There should be no huge steam draw when a charge heats because this happens continually eliminating poor coil drainage due to high load.  Conversely, there is no low-load period at the end to cause could flooding because of low delta P across the traps.

Does the mill do enough of one or two products to keep the kiln feed?  You can feed two products at different rates, one from each end.  If the mill has 10 different products on 10 different schedules, it might not work well because of the product changes.  Although, you might make it work, a few high volume products would probably be easier to manage.

Do you have good stacking and loading practices?  You don’t want piles falling in the kiln or weights falling.  Adding weights will increase degrade if stacking is not done well.

Part of the energy efficiency is from condensing water.  You must consider how to dispose of the water.  Maybe to municipal treatment?  I would assume it cannot be simply discharged because of BOD.

There are lots of these in the south and I'm sure your vender could arrange for you to see one.

I know "continuous kilns" save time. Does anyone have any data showing other benefits such as saving energy?
Dry Kiln Maintenance / Re: lignomat
« Last post by Josh Goin on February 18, 2015, 01:39:55 PM »
If you are running a traditional Lignomat kiln control system there are only a few things that will shut your kiln down.

Loss of EMC/WB or DB readings on both sides (can not regulate what it does not know)

Fans running in wrong direction (only seen on installations or after reworking the MCC or VFD's)

Damaged PLC or control modules.

These are the most common. Look at the kiln histories for errors, the errors may go away on the screen if the kiln is down for a while but will be recorded in the history.

If nothing is smoking you can swap PLC's and other electronics and track down the problem. Call Lignomat  for support, spare parts are on hand even for old control systems.
