| Research Abstract |
We observed that the stable combustion region for flammable plastic dusts was extended by using a high-temperature oxidizer diluted with superheated steam. Especially, for larger dusts and flame retardant plastic-dusts, a remarkable extension of the combustion region appeared in the high-temperature oxidizer. In the cases for fine dusts or in higher temperature of oxidizers, the light from luminous flame, which can be usually observed in the plastic-dust combustion, is decreased, and the unburned plastic in the burned gases decreases markedly.
