Heat Media Options
Wellons Indirect Heating Systems include Steam, Thermal Oil, or Hot Water as the heat medium. The heating systems are divided into stations and zones within the kiln for precise lumber drying.
The steam heating system receives steam into a supply header from a boiler system which branches into several controlled zones. Each zone is controlled by either a pneumatic or electric valve which controls the flow rate of steam to each coil bank. Each coil bank is individually trapped and drains to a condensate return system. Humidity is vented through automatically controlled vents. Wellons designs systems for high pressure or low pressure steam depending on the drying application.
Thermal oil or hot water is pumped from the respective supply via a Primary Loop which sends and receives the fluid to and from the system. The fluid is directed to a header at each individual chamber where 2-way control valves adjust the fluid rate to the coil banks. Each valve and coil bank make up a zone within the system. The coil banks are fabricated of continually-welded, serpentine coils (fin pipe). The fluid is returned to the pumping system to reheat the fluid and return it back to the system.
Overhead heating coils are standard equipment in side-loading kilns. For larger capacity kilns, hinged, swing-out center coils can be provided.
Wellons manufactures their own standard and high heat release coil banks. Many options of fin pipe are available based on heating requirements of the customer, including:
Direct-Fired systems circulate hot gases throughout the kiln utilizing an overhead supply and return ducting system. Direct-Fired heating systems receive hot gases from a supply burner. The gases are directed through overhead supply ductwork into the kiln and distributed using slide-gates along the length of the overhead plenum ducting. Excess gases are directed through return ducting into the recirculating fan. Heat supply options include Direct-Fired Biomass, Natural Gas, or Propane.
Features
These kilns feature Wellons Canada’s innovative cantilever I-beam monorail door carriage system designed for ease and reliability of operation with a hydraulic door carriage.
Air circulation options are single or double air pass, and fan motors can be located internally or externally.
All side loading kilns are equipped with two ground level mandoors for safe, easy access. An overhead mandoor is also available.
Electronic wet bulbs provide improved accuracy and easy of operation and maintenance.
