With experimental measurement and analytical technology, the research of fire propagation over the surface of some combustible solid is conducted. Within mini-typed wind tunnel, the fire propagation over some typical solid surface under different air stream is studied. Four types of materials were studied： thin paper, typical upholstery wood (three-ply, five-ply)and the commonly used thick paper for packing. The effect with the conditions of water mist loading is analyzed and some results are gained, which may give some instruction for the project work.
