SYSTEM USING OVER FIRE ZONE SENSORS AND DATA ANALYSIS

摘要

A system for analyzing the quality of combustion in the vicinity of the over fire zone of a combustion system includes at least one lens assembly mounted to a wall of the combustion system in the vicinity of the over fire zone. One or more photo-detectors are used to measure the intensity of light emitted in the ov er fire zone. A data acquisition system is connected to the photo-detector assembly via a communication link and includes an analog-to-digital converter and data buffering device f or converting the light signals to digital signals. A computer analyzes the digital signal s with linear and nonlinear signal analysis techniques.
