From Art to Science: Quantifying Infrared Temperature Corrections

Presented By

Nagy Wassef - Quest Integrity

Conference: Galveston 2019

The application of infrared (IR) thermometry is an excellent diagnostic tool for detecting hot spots and heat distribution non-uniformity in fired heater tubes. In order to fully capture the complete capability of IR, a proven methodology is essential to measure accurate temperatures in a repeatable process, ensuring the long-term integrity of fired heater assets.

This presentation will feature a real-world case study and will discuss specific aspects involved in obtaining accurate and repeatable infrared temperature measurements of fired heater tubes. The project involved IR temperature measurement on a cabin heater, and demonstrates a number of common errors (and solutions) encountered during IR surveys. Further case study examples will illustrate the environmental and instrumental factors of an effective IR inspection program.
