Radiation thermometry: Fundamentals and Applications in the Petrochemical Industry.
Author: Peter Saunders
Temperature is one of the most critical parameters in the operation of a petrochemical plant, governing both efficiency and reliability. The non-contact technique of radiation thermometry is recognised as the only viable method for measuring temperatures in the harsh environments found in the petrochemical industry. However, meaningful measurements can only be made through a detailed understanding of the instrumental and environmental factors that more often than not influence a radiation thermometer’s readings.
This tutorial text provides an introduction to the subject of radiation thermometry, focusing on sources of measurement error and giving advice on methods for minimising or eliminating these errors. Topics covered include:
- blackbody radiation, emissivity, reflection errors, and atmospheric absorption and emission;
- commonly used radiation thermometer types;
- uncertainty calculation; and
- procedures for in-house calibration of radiation thermometers.
Included is a chapter containing detailed measurement examples for a variety of furnace types and operating conditions found in the methanol, ammonia, and refining industries.
Although intended for use in the petrochemical industry, the advice given in the book is applicable to most high temperature processing industries.
