The plant operates four long, wet kilns and burns 75 to 80% waste fuel. Conventional acid resistant fiberglass filter bags were previously installed in all the baghouses. Conventional filter bags provide effective bag life of eighteen months to two years. Maintenance is high with respect to dust build-up on the clean air plenum floor and bag failures generally occur at the ring covers. Differential pressures operate between 4 to 5" w.g. with conventional filter bags.

Date Installed: March 1997
During March 1997, a new Fuller reverse air baghouse was installed and equipped with GORE® membrane/acid resistant fiberglass fabric (10 oz/yd2) filter bags. Since installation, the baghouse differential pressure is less than 3.5" w.g. The floors of the clean air plenums are free of dust. There are no visible particulate emissions.
