Pallet kiln venting heat recovery

Heat%20recovery%20system%20installed%20on%20a%20pallet%20kiln.If you are only heat treating pallets there is no reason to install heat recovery on the power venting.

However, if you are going to be drying green pallets on a regular basis installing heat recovery on the power venting may be very beneficial. The heat recovery system pre-heats the incoming air using the hot/humid exhaust air in an air-to-air heat recovery system developed by Kiln-direct. These units can even be installed on existing kilns.

General example of efficiency number on a standard heat recovery system

Hot exhaust air into heat exchanger 200F
Outside incoming cold air 50F
   
Temperature rise efficiency 30-40%
Income air temperature rise
through air to air heat exchanger
45F to 60F
   
Heated incoming warmer air 95F - 110F
   
These are common numbers we see on pallet kilns with the heat recovery system installed.

The temperature rise efficiency is not the same as energy savings.


Each kiln normally gets two heat recovery systems installed (one on each side of control shed).

The payback and savings of the heat recovery systems gets better and better as fuel heating cosst increase.
