Systematic furnace audit results in several benefits. Continuous monitoring of decisive areas allows preventive correction of problematic situations before they become critical. It guarantees the stabilization of the glass quality and the furnace operability, with reduction of maintenance costs. For the detailed assessment of the condition of the furnaces, we offer, through our partner Glass Service, a wide range of resources.
VISUAL OBSERVATION OF REGENERATORS
Using common photographs combined with a patented method, we apply visual observation to determine the expected life of regenerators and to support decisions regarding possible repairs.
INFRARED INSPECTION OF EXTERNAL WALLS, CROWN ARCH AND BOTTOM
We perform the infrared evaluation on the accessible surfaces of the furnace. As a result, we identify the presence of possible critical areas of heat loss, hot spots, presenting recommendations for operational improvement and greater energy efficiency.
INTERIOR INSPECTION BY ENDOSCOPY
We prepare technical reports evaluating the condition of the furnace, with recommendations for repair and operational improvements. The analysis is made possible by performing comprehensive endoscopy of the ovens:
Expansion joints of the crown arch, openings and presence of condensates
Corrosion, spalling, material failure, brick displacement
Sloped bricks, joints and corrosion
Feeders, regenerators, recuperators
Complete furnace heat balance
Furnace temperature profiles
Use of optical pyrometers
Use of gas analysers (O2, CO and others)
Evaluation of the furnace superstructure by endoscopy
Evaluation of external temperatures with infrared cameras
