석탄연소 반응속도에 따른 석탄화염 형상의 패턴 관찰 = A study on flame pattern according to kinetic parameters in coal combustion modelling

다국어 초록 (Multilingual Abstract)

As a variety of coals are used in the industrial furnace, reactivity of each coal should be considered. It has influence on combustion characteristics, such as flame pattern, burnout, and NOx formation. In coal combustion modeling through general purpose CFD analysis, reactivity of coal is simply represented by kinetic parameters, such as pre-exponential factor and activation energy. Therefore, effects of various kinetic parameters should be interpreted. In this study, flame pattern is simply interpreted by adjusting the kinetic parameters in reasonable range through references. Comparison between measurements and modeling is presented in terms of the flow and flame pattern within the reference coal burner. Thereby, appearance of flame shape and temperature distribution are obtained according to adjustable kinetic parameters.
