Simulator used for researching spreading of ejected flames in long and narrow limited spaces in wind environments

The invention discloses a simulator used for researching spreading of ejected flames in long and narrow limited spaces in wind environments. The simulator is capable of simulating spreading conditionsof ejected flame, of fire which breaks out in the long and narrow limited spaces such as in streets or valleys and has one side pressed by different wind environments, in a laboratory, and influencesof different wind speeds, different widths of the long and narrow limited spaces, fire source power, size of a fire breakout room opening and a fire breakout room structure on spreading properties ofthe ejected flames in the long and narrow limited spaces can be researched. The simulator comprises a main body, external baffle walls, a wind supply system and a matched measurement and control system. The main body and the external baffle walls constitute the long and narrow limited space, so that the simulator is simple in structure and convenient to operate, and by combining the main body with the external baffle walls
