A visit was made to the Drexel Heritage Facility No. 60, Morganton, North Carolina for the purpose of observing the processes and associated controls for veneering wood panels using heated platen presses. Specific concern was expressed about controlling formaldehyde emissions. At this specific site, veneered panels were produced by both the hot press and the radiofrequency (R/F) press methods. A canopy hood exhausted through a duct to a roof fan was installed about 4 feet above the inspection platform of each feed through press. A small canopy hood covers a small mixer on the main floor. Auxiliary fans were placed throughout the facility. A few ceiling vents were noted, but the only makeup air was the filtered air returned from the dust collection system in winter. Each canopy hood captured only part of the emissions which rose from the platform. The volumetric airflow rate was not sufficient to capture vapors much beyond the boundary of the large canopy opening. Partial shift time weighted average formaldehyde concentrations were all less than 0.5 parts per million (ppm), except around the large R/F press where some peak concentrations were 3 ppm. The author concludes that this facility offers a unique opportunity to study the effectiveness of a canopy hood over an unloading platform.
