A Quiet Workhorse for Steam, Heat and Process: the BTN350-650 GLE BLU

Dual-fuel burners rarely make headlines, yet they set the daily rhythm of many factories. The BTN350-650 GLE BLU series, rated 600 kW to 6.15 MW, is one of those unobtrusive units that plant managers tend to remember for what does not happen: no unplanned stop, no fuel shortage panic, no after-hours call-outs for emission exceedances.

Dual-Fuel Flexibility Without Disruption
The burner keeps two strings to its bow. A wide-band, low-pressure gas train feeds clean natural gas; a separate gear pump delivers light oil. Change-over is automatic and bumpless, so boilers, dryers or thermal-oil heaters can follow whichever fuel is cheaper or simply available that week. No manual re-tuning is required; the electronic ratio control, driven by three-phase servos, recalculates air, gas and oil flows every second and trims the curve inside ±1 % of the set-point. The result is a flat, neutral flame that stays barely above the excess-air line across the whole 10:1 turn-down.

Low-NOx by Design, Not by Add-On
While output is quietly adjusted, NOx is quietly suppressed. A staged, lean-head flame holder keeps peak temperature down; internal flue-gas recirculation is built in, not bolted on. On gas, nitrogen oxide stays below 80 mg/m³ at 3 % O₂ without external catalysts; oil figures are only marginally higher. The numbers are verified on a portable analyser, not on paper, and hold true from 600 kW up to the maximum 6.15 MW.

Servicing Made Simple
Servicing is equally low-drama. The hinged burner door swings open like a car bonnet; the mixing head and oil atomiser slide out as one cartridge, so the boiler casing stays closed. A UV sensor watches the flame, a differential pressure switch guards the fan, and every plug is IP44. The only tool normally carried to the roof is a 13 mm spanner.

Ready for Global Deployment
Baite builds the BTN series in its own Zhejiang works. Technical files are ready for CE marking; language packs for displaying already cover English. Commissioning can be done by a local technician with a mobile app; no laptop, no licence dongle, no hidden menus.

Steady Performance in an Unpredictable Fuel Market
In short, the BTN350-650 GLE BLU is not a revolution—just a dependable, quietly compliant way to keep kilns, reactors or district-heating plants on line while the fuel market does whatever it does next. Welcom to click our office website:www.baiteburners.com
