The preheat system consists of one exhaust ramp and one measurement ramp. The main task of this system is the total burn- out of the tar volatiles.
Exhaust Ramp including:
- automatic damper control for each flue
- flue temperature control for each flue
- main temperature control
- main draft supervision
- Opacity sensor for pitch burn detection and optimization
- Flexible boot, high temperature resistant up to 900 °C
- PLC control
Measurement Ramp
The Measurement Ramp includes the following components:
- draft sensors with “life auto-zero” calibration every hour, free of maintenance
- flue temperature sensor type N for each flue
- independent PLC control, no wire connections to Exhaust Ramp
