Experiments have been carried out to develop the high efficiency combustion technique, which can realize the high energy saving and low emission of CO_2, by means of the utilization of electro-magnetic wave at the range of far infrared ray. Especially the study will be focused on how the combustion of hydrocarbon fuel including gas and spray combustion is affected by electro-magnetic wave at around 1200cm^<-1> in wave number, because the substances like methane and its combustion precursor produced by thermal decomposition during combustion process have an ability to absorb the electro-magnetic wave around 1200cm^<-1> of wave number. The evaluation of electro-magnetic wave on hydrocarbon fuel combustion is examined by measuring the fundamental combustion characteristics such as temperature distribution and combustion rate of diffusion flames in the case where the electro-magnetic wave exists or not. These data are obtained and analyzed by taking the direct color photographs with high speed digital video camera equipped with two-color pyrometer. These data indicate that the electro-magnetic wave is very effective to promote the combustion reaction rate of hydrocarbon fuel and is also very effective to realize the energy saving for boiler combustion.
