ABSTRACT
Temperatures in boilers, kilns, and furnaces in the oil rening, steel, glass, trash-to-steam, cement, power, pulp and paper, and other industries can reach 4200°F. It is critical that operators monitor the combustion in order to know, in real time, what is happening inside the “rebox,” and then take corrective action where necessary. Are burners igniting correctly? Are ames impinging on the inside walls, potentially piercing them? Is the re smoking, a sign of incomplete combustion? Watching the ames 24/7 provides certainty that the chamber is running with maximum cost efciency and safety. You can y an airplane without windows, but why would you want to? Likewise, why would you want to operate a combustor of any kind without being able to observe the quality of your combustion?
