Low 氮氧化合物 Burners and 燃烧系统

Effective 氮氧化合物 reduction components and strategies

燃烧 & 燃料系统

自1971年以来,B&W卖出了低NOx combustion systems for more than 120,000 MW of generating capacity in both new and retrofit boiler applications. 我们的低NOx burner technology has been successfully applied to a broad range of B&W和非b&W units with varying fuel characteristics and boiler arrangements. We also pioneered the development and application of NOx ports and air staging for reducing NOx 排放. Combined with our other technologies, such as Burners and selective catalytic reduction systems, overfire air systems are part of an overall NOx 减少的策略. B&W also offers new and replacement FPS gas, oil and dual fuel igniters, igniter auxiliary equipment, optical and fiber optic flame scanners and control systems for wall-fired and corner-fired boiler applications.

Our combustion solutions include:

airjet低氮氧化物Burners

airjet®低氮氧化合物Burners

B&W engineers designed the AireJet burner with an innovative burner structure — a burner built around a center jet of air, encircled by the fuel stream, and then wrapped in additional combustion air

  • Pulverized coal-fired boiler applications
  • Much cleaner burning so it requires less excess air to minimize carbon monoxide (CO) and unburned carbon
  • Higher boiler efficiency and improved plant heat rate
  • Excellent flame stability and turndown
