Ketchikan Pulp Co. (KPC) is a 600-b.d. Ton/day sulfite mill located 679 Alaska Airlines miles north of Seattle on the island of Revillagigedo. Designed to produce 860 psig steam at 825[degrees]F, each of the boilers is fired off a combination of No. 6 oil and waste wood. This paper reports that in 1984, a rotary bark dyer was installed in series between the existing boiler I.D. fans and the boiler stack. This system consists of a direct-contact rotary dryer unit followed by an additional I.D. fan and four cyclone separators. The combustion gases then return to the existing stack by way of the existing I.D. fan discharge ducting. This unit was designed to operate at a flue-gas inlet temperature of 550[degrees]F and maintained a discharge temperature of 300[degrees]F. The unit was designed to process approximately 360 units of hog fuel per day, drying it from 60% moisture to 40% moisture in a single-pass operation.
