Abstract

Kiln drying lumber is an energy intensive process. Although thermal energy represents the majority of the process energy consumed, electrical energy is required to maintain air flow through the lumber. The volume of air flow needed for drying depends on a number of factors including the type of wood used and its moisture content. Greater moisture content consumes more energy. Air flow requirements decline during the production cycle as the lumber's moisture content decreases. This is particularly true with hardwoods such as oak.

This article provides a case study that validates electrical energy savings from the recent installation of five new kilns. The addition of variable frequency drives on twenty-five fan motors at the Matthews Casket Company's manufacturing facility improved process energy efficiency.
