• Utilization of Infrared Inspection: A Comprehensive Distillation Furnace Inspection Program
  . Furnace Inspection Program. John R. Coleman, P.E. Infrared Scanning Services, Inc. ABSTRACT. Tube metal temperatures are critical to furnace operations. When operating a furnace close to the maximum. allowable tube metal temperature, changes of less than 200° F can dramatically reduce tube life on tubes...

In oil fired furnaces, however, the images sometimes show higher temperature that the actual one. due flame...
• Application of Ultrasonic Cleaning
  . A few examples of measuring cleanliness include various levels of particle count, microscopic inspection, and a variety of adhesion tests, including the clear tape test that has the ability to remove additional contamination. These are just a few examples of cleanliness measurement. Ultrasonic...
