AMETEK Western Research's SpectraTemp™ is an optical temperature measurement system that provides continuous, accurate, and reliable temperature monitoring of hot, particulate-laden gas streams.
SpectraTemp has most commonly been used for monitoring furnace exit gas temperature in utility and industrial boilers fired by coal, heavy oil, wood, or municipal waste. In these installations, SpectraTemp reduces operating costs by providing
- better control of furnace wall blowers and soot blowers,
- better burner control (tilt and excess air), and
- superior steam temperature control.
DIRECT MEASUREMENT
SpectraTemp determines particulate temperature by measuring light emissions for the particulates at three different wavelengths. These wavelengths are selected to avoid interferences from cool, heat-transfer surfaces (e.g. boiler walls). SpectraTemp's design gives it a unique capability to determine a line-of-sight average temperature all the way across a particulate-laden stream. Automatic calibration, fault detection, and alarms are incorporated into SpectraTemp; and both analog and digital outputs are supplied for interfacing with plant control systems.
