註釋Over 10,000 horsepower of fan motors are installed in 400 lumber dry kilns in Ontario. Each kiln operates for over 7,000 hours per year at a cost of about $3m. When air flow is maintained efficiently by using adjustable speed drives to reduce fan speed, the electrical consumption of the fan motors can be reduced by as much as 50%. This paper describes a demonstration project that found a method, using the temperature drop across the load (TDAL) tool, to determine the fan speed reduction schedule without affecting the lumber drying process; and measured the savings from using adjustable speed drives to reduce fan speed.
