BD 9-12 GE FGR Series Split Type Low NOx Burner is a split type burner family for large boiler rooms, district heating, and industrial process heat applications, covering the 1500 to 12500 kW output range.
Operating Modes
Two-stage; Progressive modulation; Electronic modulation
Key Features
- Split type layout supports large boiler rooms and process heat systems, including hot water boilers, steam boilers, and thermal oil furnaces.
- The system can be matched with an induced draft fan according to firing capacity, boiler back pressure, and fuel conditions.
- The program controller and flame detector include 24-hour flame signal self-checking.
- A digital pipeline control system uses three servo motors to control combustion air, gas volume, and flue gas recirculation volume.
- Flue gas recirculation mixes part of the exhaust gas with combustion air before combustion, lowering chamber temperature and oxygen concentration to suppress NOx formation.
- Multiple nozzles distribute combustion and help reduce localized high-temperature oxidation.
- The steel-welded sealed housing has an openable top cover for internal maintenance.
- UV flame detectors are used for flame supervision.
- Electrical protection rating is IP40.
