APPLICATION REPORT

Power Plant Coal Boiler

Industry: Power Generation
 
Description of Equipment: Peep doors, thermocouple ports, and water cannon ports
 
Problem: Repairs needed to be made with minimal downtime
 
Solution:  Use Thermbond products that require no curing or lengthy dryout

Power Generation Coal Boiler - Water Cannon port repaired with Formula 6P	Repair over old refractory in either peep sites or thermocouple openings
Repairing area over 4" thick with Formula 15 R	Trowling Formula 6P inside a Power Coal Boiler around a water cannon port

Product Being Replaced: Conventional Ram Refractory

Products Applied: Formula 6 P and Formula 15 R

Method of Installation: Equipment Used: Pnemautic ramming hammer and 3/4 hp drill with mixing blade.

Scope of Work: Mixed Formula 15R with hand mixer. Rammed material into place over existing refractory. Installer was pleased with the consistency. Initially Formula 6P was mixed  into a thin trowelling consistency.The trowelling cosistency worked well for thin overlays.  Additional batches were mixed so the Formula 6P could be made into a ball (like for ramming). The material was spread out on plywood to slow down the setting time. Unused material was moved and stored in an area where the temperature was 65F, as opposed to keeping the material in the boiler where temperatures were  95-100F, as they had done prior. This extended the working time for Formula 6P pleased the installers.

Installation Date: October 2007
