Fundamental research has been carried out to utilize the asphalt, one of the residue oils after distilling crude oil with oil-in-warer emulsified technique. The ignition and combustion behavior of a small amount of spray with asphalt-in water emulsified fuel (As/W) were observed in a large vertical electric furnace in order to predict the behavior in a practical furnace combustion. The experiments were carried out for two representative kinds among the As/W fuels used in the experiments of the suspended As/W single droplets prepared with some kinds of surface active agents in a small electric furnace, and 'C'-heavy Oil. High speed video recordings and the chemiluminescence signals of both OH and CH radicals reveals that the micro-explosion was induced as well in the spray combustion of the fuels observed in the combustion behavior of the suspended single droplets in the small electric furnace. Each fuel showed peculiar ignition and combustion behavior, and especially As/W emulsified fuel-J (As/W-J) had a very strong micro explosion similar to the behavior of a single droplet.
