To find out practical design of high-rise building external wall fire protection, a preliminary study of water spray curtain was performed. The characteristic of the spray was analyzed through experiments. Basic characteristics such as exponential relationship between discharge rate and working pressure of the nozzle were obtained. The spread behavior of water film on the wall, such as spread width, was tested and analyzed. Feasible design and apply layout of the spray system on external wall was presented. The probable design was proved to be much more energy-saving than traditional sprinklers. In the end, a workable pattern of application was presented and further explained how the design worked and reduced construction energy.
