Bloom Engineering Benefits For The Boiler Industry

A unique benefit to the boiler industry and industrial boiler market is Low excess air operation. Additional features and benefits include:

• Stable, compact flame even with high levels of FGR.
  
• Very low CO even at under 1% O2 due to “fine-grained” mixing.
  
• Capable of gas and oil firing.
  
• Simple, rugged construction with no moving parts and low maintenance.
  
• No devices protruding into the firing chamber.
  
• No steam injection required (would reduce system efficiency and could increase fouling).
  
• Ultra low NOx can be achieved with cold or preheated air combustion.
  
• Turndown of 10/1 for natural gas and 8/1 for oil operation.
  
• Gas-only burner does not require staging; results in smaller/less expensive construction.
  
• Burner can actually enhance boiler efficiency due to ability to run at very low excess air levels.
  
• FGR does not reduce combustion efficiency in boiler application (with proper insulation of return piping).
  
• FGR system can be implemented without an additional fan.
