The condition of glass furnace refractories is vitally important to safety and process efficiency, especially towards the end of the life of the tank. Deterioration of the refractories can increase fuel costs, and may cause glass break-outs or refractory failure.
Monitoring the exterior of the melt tank with a thermal imager can provide an indication of any hot areas which may indicate refractory damage. It also gives an early warning of potential glass break-outs.
Continuous thermal imaging can also be used for accurate interior monitoring, establishing temperature trends throughout the furnace. It also detects cooler spots which may indicate refractory damage.
Detection of damage to the tank allows early maintenance and extends the tank’s lifespan. Around 70% of container glass production costs come from energy, so preventing cracks and lost heat produces significant savings. Early detection of glass break-outs enhances plant safety.
