Electrical Savings from Fan Speed Reduction in Lumber Dry Kilns
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.
