A Closer Look at the BAITE BTN550-650GHAC/GHAE Series Dual-Fuel Burner

2025-09-05

When reliable heat is essential and fuel flexibility matters, the BTN550-650GHAC/GHAE Series offers a straightforward solution. Designed for users who switch between methane gas and heavy oil, this burner handles both fuels without requiring hardware changes on the fly.

Key Features

Dual-fuel readiness – Electronic change-over between methane gas and heavy oil is built in. No manual nozzle swaps or complex adjustments are needed.
Two-stage, sliding or modulating control – Choose the output regulation mode that matches your process: simple high/low, cam-based sliding, or full electronic modulation.
Electronic ratio management – Independent three-phase servomotors adjust air, gas and oil flows, letting the burner track load changes while keeping excess-air levels stable.
High-pressure mechanical atomisation – A separate pump motor delivers oil to the nozzle at the pressure required for clean combustion, even with higher-viscosity heavy oil.
Hinged design – The atomiser and combustion head swing open, so the burner can be serviced while remaining bolted to the boiler.
Standard safety devices – UV flame supervision, air-pressure switch, dual fuel shut-off valves and an IP40 electrical cabinet are included.
Low-noise air intake – An internal silencer liner reduces fan noise without add-on accessories.

Typical Applications

Steam and hot-water boilers in textile, food and chemical plants
Dryer lines and kilns where fuel availability can change seasonally
Sites already using heavy oil that want an economical path to add gas firing

Installation Notes

The burner is delivered ready for flange mounting; match the boiler front plate to the drilling pattern in the manual. A 3 × 380–415 V, 50 Hz supply drives both fan and pump motors. If local gas pressure is below 50 mbar, a separate gas booster may be required. For heavy oil, pre-heating to 80–100 °C is recommended; BAITE supplies the electric heater set as an optional module.

Maintenance

Daily: check oil temperature and filter condition
Monthly: inspect the UV cell lens and clean if soot is present
Annually: verify servomotor cams, replace nozzle and clean the blast-tube

Spare parts are interchangeable across the BTN550 and BTN650 frames, keeping stockholding simple.

Bottom Line

The BTN550-650GHAC/GHAE Series is aimed at operators who need a robust, no-frills dual-fuel burner that can follow a modulation signal while meeting local emission limits. With electronic fuel change-over and independent servo drives, it removes the complexity usually associated with dual-fuel firing, making it a practical choice for process plants worldwide.
