Abstract

A number of on-line infrared process signature measurements have been made through combustion atmospheres. Examples include signature studies of jet engines, piston engines and coal gasification reactors. Typical problems include operation in the presence of pressure as high as 1800 psi, temperatures as high as 3200°F, and explosive, corrosive and dust-laden atmospheres. Other problems have required the use of long viewing tubes of small diameter which sometimes become distorted as the temperature of the observed process increases. Calibration problems have resulted from the use of purge gases to clear viewing tubes, and the obscuration of view ports by combustion products. The paper describes solutions that have been employed to counteract many of these problems and reviews the areas in which better solutions are required.
