The blast furnace doors were coated with SUPER THERM ® to bring the surface temperature down, from 150C \ 302F to 70C \ 158F via backside conduction, to meet code for surfaces exposed to human contact. This required 50mils DFT of SUPERTHERM ® applied in multiple coats. Today we would use HOT SURFACE COATING ® which had not yet been developed and accomplish the same thickness in a couple of coats. The air leaks were caulked with OMEGA FIRE ® (SP2001F) which is still in place today.
These
containment tanks located at the GVRD Waste Incinerator process acidic ash. In
1999 they were coated inside and out with a primer coat of RUSTGRIP
®, a base coat of SUPER THERM ® and a topcoat of ENAMOGRIP
®. In 2002 the tanks were checked for structural integrity.
The uncoated tanks were discarded and replaced. The coated tanks were touched
up and returned to service.
