PyroMetrix
The PyroMetrix™ Acoustic Pyrometer is a non-contact
measurement device that obtains highly accurate
instantaneous gas temperature data in any area of the kiln,
combustion and cooling zones. The PyroMetrix system utilizes
the principle that the velocity of sound through a medium is
related to the temperature of the medium. Temperature data
is spatially averaged and can provide zonal temperature
maps.
The PyroMetrix sends a sound wave from the Acoustic Signal
Generator (ASG) across the chamber to one or more Acoustic
Signal Receivers (ASRs) mounted on the opposite side. The
time required for the signal to traverse the chamber is
related to the gas temperature.
The measurement is not sensitive to changes in clinker dust
concentration. Because the components are all mounted on the
outside of the chamber, they are not subject to abrasion and
heat damage.
Proven applications for PyroMetrix in the cement industry
include:
Clinker Cooler: Optimizing heat recovery from secondary air,
reducing fan draw and reducing maintenance costs.
Calciner Exit Temperature: Ability to directly control fuel
rate, measurement in difficult locations such as hot spots
up to 2400°F, measurement in dusty, “fierce sandstorm”
environments, and variations across width and breadth.
Kiln Exit Gas temperature (KEGT): Detection of unstable or
malfunctioning burners, heat transfer optimization and
reduction of NOx emissions.
Tertiary Air: Ability to optimize heat recovery and achieve
complete heat balance calculations.
