#6 - Integrating Kiln Services

Case Studies

Over the past 30 years, we have often embarked upon projects which have not traditionally been considered within our scope of experience. As with all our projects, our reputation for delivering on time, every time a winning solution allows our engineering team to continue offering a wide range of services.
 

Case Study 6
- Integrating Kiln Services

 
Problem:
Our customer wanted a seamless project to improve drying quality and to provide additional drying capacity at their facility utilizing continuous drying kilns (CDK technology).

Case Study 6 - Details

Details:
The thermal energy for the CDKs was to be supplied from direct fired gasifier heat plants using their sawmills biomass residuals.

In this instance the residual fuel is green/wet sawdust with a moisture content (MC) of 56% on a wet basis and sometimes higher.

This green sawdust fuel had to be transported from the sawmill, where it is generated, to storage silos adjacent to the new gasifier heat plants at the CDK chambers.

 

Solution

An integrated project where the following major items of equipment were installed:

• Two Windsor direct fired CDK systems
• Two KDS gasifier heat plants
• Dryspec and DryTrack Echo PC/PLC controls packages with live MC monitoring of the timber during drying.
• Windsor pneumatic fuel transfer system including augers, conveyors, metering and surge bins and positive displacement blowers.
• Concrete storage silo with unloaders and silo-top discharge cyclones

The Outcome

The whole project including manufacture, freight, project management, installation, commissioning and training was very successful: it was safe, on time and in budget and has resulted in repeat orders from the customer for four of their other sawmill facilities. Together the two Windsor drying systems dry over 480,000m³ of high grade structural timber per year.
