Environmental Equipment: Nitrogen Oxides Control

B&W offers a wide variety of options for nitrogen oxides control equipment.

Selective Catalytic Reduction (SCR) Systems are the technology of choice as the most effective method of post-combustion NO_x reduction.

B&W is a leader in providing complete project packages including system design and construction, ammonia storage and delivery systems, reactor and catalyst design, control systems, and balance of plant equipment. Our extensive experience includes both new boiler installations and retrofit applications.

Computational fluid dynamics and physical modeling are used to study gas characteristics and to assist engineers in designing the most cost-effective NO_x reduction system.

Additional NO_x reduction can be achieved by integrating low NO_x burners and staged combustion (overfire air) into the overall system. B&W's successful history of reducing NO_x emissions on fossil-fired boilers includes more than 125,000 MW of low NO_x combustion equipment.

Our NOx-reduction options include:

• Selective catalytic reduction (SCR) systems
• Selective non-catalytic reduction systems
• Low-NOx burners:

  - DRB-4Z^® low NOx coal burner
  - AireJet^™ low NOx coal burner
  - XCL-S^® low NOx oil and gas burner
  - Dual zone NOx port (overfire air system)
  - Igniters
