Drying Lumber with a Thermal Fluid Dryer
The thermal fluid heater provided a number of advantages over the boilers used in four of the five kilns on site. Although the advantages of thermal fluid systems are somewhat offset by their initial cost compared to boilers, the systems lack the potential for corrosion that is common in boilers, and there is no need for water treatment. Thermal fluid heaters also and do not require annual shutdown for inspection, have no blow down, and do not require cool wastewater or maintenance of steam traps.
The heater's burner is fired with natural gas, and the three-pass heater design is energy efficient because it ensures that more heat from the burner is transferred to helical coils, reducing the amount of heat that exits out the exhaust. The vertical configuration of the heater allows it to fit well into limited floor space.
