Key Features
- Dual fuel configuration supports gas firing together with light oil firing.
- Air and gas mix at the blast pipe, while light oil is atomized mechanically at high pressure through a nozzle.
- Combustion air and blast-pipe settings can be adjusted during commissioning to tune combustion performance.
- The mixing unit and atomization unit can be removed for maintenance without removing the burner from the boiler.
- Electronic proportional control uses three-phase servo motors to manage the gas, oil, and air ratio.
- The hinged body opens naturally for easier inspection and service access.
- Combustion air intake includes an air-flow adjustment device and a noise-reducing inlet design.
- A high-temperature stainless steel flame disc is used at the burner head.
- An independent motor drives the oil pump.
- UV flame supervision is provided by an ultraviolet phototube.
- Electrical protection rating is IP40.
