High-pressure optical combustion probe

PDF Version Also Available for Download.

Description

An optical access probe was developed to meet the demands of a gas turbine combustor in a Cooperative Research and Development Agreement (CRADA) with the Westinghouse Science and Technology Center. The probe is water-cooled, has no external fittings, and is pressure-sealed with a conventional compression fitting. The probe utilizes a 1.0-mm diameter sapphire rod as a lightpipe for optical access and fiber optic coupling to the spectroscopic experiments. This is coupled with a fused silica optical fiber to the optical experiments employed to study the combustion process. The probe has been tested to 10{sup 6} Pa in a test combustor ... continued below

Description

An optical access probe was developed to meet the demands of a gas turbine combustor in a Cooperative Research and Development Agreement (CRADA) with the Westinghouse Science and Technology Center. The probe is water-cooled, has no external fittings, and is pressure-sealed with a conventional compression fitting. The probe utilizes a 1.0-mm diameter sapphire rod as a lightpipe for optical access and fiber optic coupling to the spectroscopic experiments. This is coupled with a fused silica optical fiber to the optical experiments employed to study the combustion process. The probe has been tested to 10{sup 6} Pa in a test combustor exhibiting 10{sup 5} Pa instability oscillations. To test its spectral range, the probe investigated OH emissions at 310 nm, C{sub 2} and CH emissions from 400 to 500 nm, Near IR emissions from 800 to 1,800 nm, and temperature measurements using an Accufiber detection system.
