Method And Apparatus For Characterizing A Combustion Flame
US Patent:
6135760, Oct 24, 2000
Filed:
Dec 31, 1998
Appl. No.:
9/223997
Inventors:
Deidre E. Cusack - Groton MA
Keith Stebbings - Bradford NH
Leo Jubinville - Raymond NH

Assignee:
Meggitt Avionics, Inc. - Manchester NH
International Classification:
F23N 508
US Classification:
431 79
Abstract:
Characteristics of a flame within a turbine or burner are determined based upon ultraviolet, visible, and infrared measurements of the flame. The measurements include a measurement of the amplitude of frequency bands that are indicative of an efficient combustion process, such as those that increase when the flame temperature increases. The measurements also include of the amplitude of frequency bands that are indicative of an inefficient combustion process, such as those that do not vary, increase a relatively small amount, or decrease when the flame temperature increases. The temperature of the flame may therefore be determined accurately, to facilitate efficient operation of the turbine or burner while minimizing polluting emissions. Contaminants in the turbine or burner are detected, and a degree of contamination measured, by detection of energy levels for particular wavelengths associated with a respective contaminant.
High Temperature Gas Stream Optical Flame Sensor And Method For Fabricating Same
US Patent:
5929450, Jul 27, 1999
Filed:
Oct 24, 1996
Appl. No.:
8/736192
Inventors:
William M. Glasheen - Derry NH

Assignee:
Ametek Aerospace Products, Inc. - Wilmington MA
International Classification:
G01J 520
US Classification:
250372
Abstract:
A high temperature gas stream optical flame sensor for flame detection in gas turbine engines, and method for fabricating same is provided. The sensor generally comprises a silicon carbide photodiode and silicon carbide based amplification hardware for generating a signal indicative of the presence of the flame. In a preferred embodiment, the photodiode and amplification hardware are disposed within a sensor housing and the photodiode is situated within a fuel/air premixer.
