Fuse Tech offers high temperature furnace inspections through the use of water-cooled periscopes. The owner is then able to view areas or actions that may not be visible through normal “line of sight” observations. This equipment has video capability that allows recording with sound, thereby making it possible to “voice over” and describe the area or action being observed. This would include the firing characteristics of burners, bubbler effect, and batch melting characteristics. Pictures on CD for powerpoint type presentations are also given, if desired, which can be used in meetings with management to describe furnace conditions and any needed repairs. Information of this type makes excellent historical records to be reviewed and updated over the campaign life of the furnace, and is useful for upper management in understanding the value of Fuse Tech’s offerings.
CHECKER & PORT CLEANING
There are two chambers within a checker, one with air entering for combustion, one for exhaust. As one chamber is heated, exhaust gases exit through the opposing side, cooling internal gases. The port is positioned on top of the checkers, with new gases injected in the port at the furnace. Over time, debris collects during the process from melted glass at the port neck and mouth, causing airflow to become restricted. Our high-pressure, custom pumps are designed specifically for safe and effective furnace buildup removal.
Today, longer furnace campaigns and smaller furnace maintenance crews mean less available labor to protect your multi-million dollar asset. Ensuring your furnace is operating in top condition will provide the highest long-term return on investment, increase production efficiency, and keep your employees free from hazardous conditions. Fuse Tech’s proprietary method of port cleaning involves ultra high-pressure water lasers to attack collected debris. The extreme pressures (up to 10,000 PSI) use very small volumes of water (~2-3 gallons/minute) which readily vaporizes after the cleaning process.
This method uses a water-cooled lance that reaches through the regenerator target wall, across the checker pack and through the port to the hot face. The lance is designed to “fire” the laser stream back toward the regenerator. Once the lance is in place, a protective shield is placed in front of the hole to stop debris from hitting the operator without obstructing their vision. Water pressure is then turned on and increased to the level needed for effective debris removal.
The operator can then slowly move the lance across the port floor, “blasting” the collected debris back into the regenerator. Due to the extreme pressure and thermal shock of the water, debris comes out of the port in small pieces, which is able to fall through the checker pack to be removed below the rider arches. This process is only done on the exhaust portion of the reversing cycle to assure that all the debris goes toward the regenerator and does not contaminate the glass bath.
Our process not only provides a cost savings, but often, in older furnaces, a reduction in fuel with resultant reduction in combustion air that may be very helpful to relieve some furnace pressure on an old and heavily worn exhaust system.
