The Jet air system is used in recuperative furnaces and oxy/fuel furnace to adjust the furnace pressure
The system consists of electric fan with variable speed modulated through the pressure control system in the cabinet which receives the 4-20 mA signal from the pressure probe.
The air is inflated after the recuperator (or after the refractory duct in case of oxy-fuel furnace) and mixed with the hot gases.
The mass increase of the fumes generates the due counter pressure in the waste duct in compliance with the pressure values demanded.
The main features are:
- High temperature resistant material
- Extended lifespan
- High reliability
- High accuracy
