BD 25-30 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 5000 to 30000 kW output range.
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.
