Furnace Exit-Gas Temperature (FEGT) Measurement System
Continuously measure Furnace Exit-Gas Temperature (FEGT) using Non-Contact Infrared Sensors to optimize overall performance of boilers and furnaces under varying conditions of coal quality, load, ash fouling, and slagging.
- Prevent failures by proactively monitoring the furnace temperature
- Determine precisely when to perform sootblowing
- Set trigger alarms to take quick corrective actions when gas temperatures approach slagging/fouling limits with continuous online monitoring
- Measure and quantify trade-offs of heat rate and NOx and SO2 emissions
- Optimize heat transfer by controlling FEGT under varying conditions
- Prevent unwanted slag accumulation at inlet pendants by controlling FEGT below ash fusion temperatures
- Reduce down time due to failures by prevention
- Easily install and maintain while boiler is online.
In many combustion processes, one of the main combustion gases is CO2. Therefore, measuring the CO2 gas temperature is a reliable measurement of the combustion temperature.
Our combustion monitoring solution is a cost effective system that utilizes the IPE 140/45 pyrometer. This is a pyrometer specifically designed for reliable “non-contact” temperature measurement of hot combustion gas containing CO2.
The system is easy to install and maintain even while the boiler is online. It allows for a very quick reaction to undesirable conditions with continuous online monitoring of the combustion temperature.
LumaSense’s FEGT solution includes:
- Infrared Temperature Sensor
