GAS BURNERS FOR REGENERATIVE FURNACES
The BDF gas burners have been designed for underport installation in End-Fired and Cross-Fired furnaces.
In order to achieve a better flame shape and length on each burner the gas is split in two streams into the burner and flows into the tank through two concentric nozzles.
The different impulse of the two streams allows controlling the flame shape and length. The knobs installed in the rear part of the burner allow adjusting the two-flow impulse in order to reach the best furnace performance.
Both the internal and the external nozzles are made of high temperature resistant stainless steel.
A special support allows adjusting the zenith and azimuth angles as well as the vertical and horizontal burner axes.
The support has been designed for tool-less adjustment as well as the burner fixing and removal.
When one of the side firing is in stand-by the relevant burner nozzles are cooled by a compressed air stream.
- High efficiency low NOx flame
- EASILY adjustable flame shape and length
- Easy angle and position adjustement
OIL BURNER FOR REGENERATIVE FURNACES
The BDF oil burners have been designed for underport installation in End-Fired and Cross-Fired furnaces. In order to achieve a better flame shape and length the heavy oil is atomized by compressed air. Both the internal and the external nozzles are made of high temperature resistant stainless steel.
A special support is available to adjust the burner position. The support enables to adjust the zenith and azimuth angles as well as the burner vertical and horizontal axes.
Before being sent to the burners the heavy oil must be heated, by a group of electric heaters suitable, at a temperature up to 120 °C in order to reduce the viscosity to a value suitable for the best combustion in the tank.
BURNERS
FOR RECUPERATIVE FURNACES
The BDF preheated air burners have been developed for Recuperative Furnaces. The hot air flow from the recuperator may be independently adjusted per each burner. In the body of the burner the air meets the fuel stream that is introduced by a gas or oil lance.
For natural gas combustion system we recommend the use of BDF special design for gas lances using a double stream of gas for a better regulation of the flame length and shape.
The burner is suitable for operation with air pre-heating temperature up to 800°C.
