The different combustion systems for liquid fuels - Section 1 - Blue & yellow flame burners

 

Swirl disk stabilized Standard yellow flame system

  • Low soot
  • Low CO (40-100 ppm)
  • High NOx (60-100 ppm)
  • Low air pressure (0,015-0,045 psi)
  • Low fuel pressure (90-175 psi)
  • Medium CO2 stability
  • In countries with more stringent emission standard not permitted
  • Swirl disk stabilized


 

Swirl disk stabilized Low-NOx yellow flame system

  • Low soot
  • Low CO (20-80 ppm)
  • Medium NOx (50-70 ppm)
  • Medium air pressure (0,03-0,06 psi)
  • Medium fuel pressure (145-200 psi)
  • Medium CO2 stability
  • In countries with high stringent emission standard not permitted
  • Medium CO2 stability
   

Swirl nozzle and flame tube stabilized

  • Low-NOx blue flame system (MB(x)) with flue gas recirculation
  • No soot
  • Very Low CO (0-20 ppm)
  • Very Low NOx (20-50 ppm)
  • High air pressure (0,1-0,45 psi)
  • High fuel pressure (145-360 psi)
  • High CO2 stability
  • In all countries with high stringent emission standard permitted

Different combustion systems for liquid fuels - Section 2

Standard yellow flame burner

  • Large flame length
  • High flame core temperature
  • High NOx level

Low NOx Burner Yellow (air staging)

  • Constricted flame
  • Medium flame length
  • Yellow flame with blue strings
  • Medium NOx level

Blue flame burner with flue gas recirculation

  • Blue flame
  • Gasification of the fuel
  • Short flame length
  • Low NOx level

 

 

Thermal NOx synthesis

The thermal NOx synthesis is subject to a complex reaction mechanism, the reaction rate at combustion temperatures above 2400 ° F increases sharply

 

  • The formation of thermal NOx increases exponentially with increasing temperature which is proportional to the concentration of atomic oxygen and depends on the residence time in the hot flame and gas zones
  • Fuel NOx is synthesis starts at 1500 ° F and is only slightly dependent on temperature
