Distiller Unit

Industry: Power

 

Application: Distiller Unit

 

Product Applied: Thermbond Formula-15

 

Method of installation: Hand Ramming

 

Equipment Used: Hobart Mixer, Wood Ceiling Form, Hand Sprayer, Pneumatic Hand Rammer

 

Problem:  Refractory in ceiling of distiller unit was cracked and damaged after less than two years of normal operation. Replacement of conventional refractory involves extensive labor and time for removal of existing material, plus 3-5 days for dry-out prior to running.

 

Solution:  Chemically bond new refractory to existing conventional refractory using patented THERMBOND Formula-15. Distiller unit was back on-line in 24 hours.

 

 

Product replaced: 70 LCC

 

Scope of Work: Chip and remove any loose refractory. Build wood ceiling form approx 1/16 of the total surface area. Wedge form in place. Treat form with liquid activator. Mix 1/2 unit of Formula 15 at a time in Hobart. Hand pack material into cavity. Pneumatically ram material to required density. Material set in 15 minutes at ambient temperature. Release wood form, retreat with liquid activator, wedge in next position. Repeat process until entire ceiling is patched

 

Follow Up:  August 2005: Repair was originally intented to be a temporary fix, customer intended to replace burner and ceiling refractory within 3 months. In follow up call with customer, 11 months after application, the patch held up so well that they never ended up replacing the ceiling (only the burner), and distiller unit continues to operate well to this day.
