Wall-Fired Burners
Reliability and Control with Low NOx
Reliable and flexible solution for traditional coals
BHI-FW has supplied over 280 Wall-Fired Boilers with installations on every continent. Our unique design incorporates a number of features that result in providing the operational flexibility demanded by the cyclic nature of today’s utility demand profile. Whether you need 100 MWe or 1000 MWe, our split backpass design, coupled with the BHI-FW Split Flame Low NOx burner and Over-Fire Air system, will provide a unit with the best available turndown and steam temperature control.
The patented Split Flame burner is robust and reliable. It offers an incredible range of settings that generate an optimized flame front with just three moving parts, while easily lending itself to a modulating control scheme for the best possible emissions control throughout the turndown range of the unit.
Designed Features of Wall-Fired Burners
- Split flame nozzle tip promotes early release and igntion of volatiles
- In-line adjustable swirler for flame shape control
- Swirled inner zone secondary air path for ignition point stability
- Dual overfire air ports for effective penetration across all loads
- Linear sleeve damper modulation for even distribution of secondary air
Simply Robust
Split Flame Low NOx Burners
- A unique 6 lobe Opti-Flow nozzle provides 50% more peripheral exposure for early burn of volatiles
- An in-line adjustable swirler mixes air and fuel for efficient combustion with low NOx, CO and UBC
- It contains only 3 moving parts and only one that modulates during operation
- It is sized to provide high exit velocities for penetration and mixing with sufficient pressure drop to maintain even distribution of secondary air
