Abstract: A combustion-zone chemical sensing system (100) is disclosed that includes pitch reflective optics (110) that collimate MIR electromagnetic energy from an input fiber (150), a reflector (120), catch reflective optics (112) that focus reflected MIR electromagnetic energy into an output fiber (152), and a detector (140) to detect MIR electromagnetic energy from the output fiber. An optical head (102) for sensing a combustion zone (104) is disclosed that includes pitch reflective optics (110) that collimate MIR electromagnetic energy from an input fiber (150) towards a reflector (120), catch reflective optics (112) that focus MIR electromagnetic energy, reflected from the reflector, into an output fiber (152), and an alignment housing that interfaces with structure adjacent the combustion zone.

Abstract: A multi-function sight port door includes a sensor mount attached at an aperture within the sight port door. A sensor is mounted to the sensor mount and configured to monitor the interior of a heater that the multi-function sight port door is mounted to. The multi-function sight port door is also configured to open to allow visual inspection of the interior of the heater while the sensor is mounted thereto. The multi-function sight port may be configured to allow for one or more of X-axis, Y-axis, Z-axis, tilt, roll, and yaw positioning of the sensor as mounted to the sight port door. The sensor may be a temperature sensor, pressure sensor, flame scanner, gas analyzer, optical-based sensor, thermal imager, thermal camera, or laser-based analyzer.
