Technology to obtain various information on velocity/concentration/ mixedness /temperature/droplet distribution using non-intrusive laser-based measurement techniques in a high-temperature and high-pressure conditions

Advanced combustor design for low emission of air pollutant through detailed analysis to combustion phenomena in complex flow field


Client / Market

  • Companies that need accurate measurement and analysis on combustion phenomena
  • Companies that need to development a combustor for boiler/power plant/heating furnace / incinerator or to retrofit old combustor for better performances


Necessity of this Technology

  • Combustion phenomena should be accurately understood and controlled to satisfy various requirements for industrial combustor, such as high combustion efficiency, low pollutant emission, wide operation range and so on
  • Accurate measurement of complex combustion phenomena in turbulent flow field is very difficult.
  • For a gas turbine combustor which operates under high-temperature and highpressure conditions, there are concerns about accessibility and durability of a sensor.
  • Therefore, non-intrusive sensing techniques (laser diagnostics) are required to measure quantitative data for various information including velocity/concentration/ mixedness/temperature/droplet distribution.


Technical Differentiation

  • Laser diagnostics applies directly to real scaled combustor and it will be conducted under high-temperature and high-pressure condition such that the reliability of data could be maximized.
  • Air flow rate 3.6 kg/s, 9.5 BarA, 900 K max./Fuel flow rate 180 kg/h (gas), 500 kg/h (liquid)
  • Because the laser diagnostics are accomplished through a specially designed optical window system, clear measurements can be made under high-temperature, high-pressure and even high-sooting conditions


Excellence of Technology

  • nowledge for laser control, optical system organization, signal synchronization, signal correction, and data analysis required for accurate laser-applied measurement
  • With simultaneous measurement of multiple laser diagnostics techniques, detailed analysis is possible.



Current Intellectual Property Right Status

  • Combustion-flow field interrelation analysis technology using simultaneous measurement of OH-PLIF and stereo PIV
  • Fuel mixedness quantification technology using acetone PLIF technique
  • Liquid fuel atomization performance quantification technology using the PDPA technique
  • Investigation of combustion instability by using high speed chemiluminescence and synchronized dynamics pressure measurement
  • High-temperature, high-pressure flow chamber design and operation
