본 연구에서는 4종류의 실험 모델을 채택하여 연소 반응용다공성 블럭(combu- stive reacting porous block)내의 화염대 위치와 화염의 온도 분포, 화염이 안정화 되는 범위를 고찰하여 내부 열재순환 효과를 규명하고 예열용 다공성 블럭(preheating porous block)과 복사 차폐용 다공성 블럭(radiative insulating porous block)의 효 과에 대한 연구와 초희박 혼합기나 저 발열량 연료의 연소 가능성을 제시하고 수치 계 산에 필요한 자료를 제시하는 것이다. This paper presents the results of an experimental investigation on one dimensional excess enthalpy flame formed in a porous block. The investigation is undertaken in order to further the physical understanding of internal heat recirculation from reaction zone to unburned mixture. Two porous blocks are placed at both sides of combustion block to control the temperature distribution in the combustion block by means of radiation heat transfer. Mean temperature measurement reveals the general nature of the reaction zone in the porous material. It is conformed that the temperature of reaction zone exceeds the adiabatic flame temperature and the flame is stabilized at the out range of flammibility limit derived by conventional burner.
