BD25-30 Split Type Low NOx Burner

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.

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.
