The experimental study of hydrocarbon fuel droplets burning in the electro-magnetic environments has been carried out to examine the effect of electro-magnetic wave on the combustion of fuel droplets. The characteristics of electro-magnetic wave developed for the study are around 1200 cm-1 in wave number, which corresponds to the absorption band of methane molecule. The combustion process of hydrocarbon fuels ultimately includes the reaction of methane and methyl with oxygen as a result of thermal decomposition. So it is very important to examine whether the combustion of hydrocarbon fuel droplets is promoted by electro-magnetic wave or not. The fuels used for the study are n-heptane, n-hexadecane, methanol, benzene, kerosene and heavy oil A. The initial droplet diameter is approximately 1.70 to 1.85mm. The acquisitions obtained here show that such electro-magnetic wave may be very effective to accelerate the combustion rate of hydrocarbon fuel droplets by utilization of resonance frequency to methane molecule.
