Based on engineering examples the paper introduces some matters that need to be considered in the design of water spray fire extinguishing system,such as determination of design flow,selection and arrangement of spray head,arrangement of deluge valve block and laying of water spray pipeline,as well as operation and control of system and selection of water source and pumps,etc.

Design and development of water spray fire extinguishing system;

In the light of the specific engineering project, the paper summarizes the main design and construction points of the water spray fire extinguishing system and it also gives the solution to the questions existing in real projects.

Reasons and prevention measures for water spray phenomenon in water spray extinguishing system;

Experimental research of suppression performance on Chinese spirits fire using water spray extinguishing system

At present, a lot of water spray extinguishing system design was performed by the designers at pleasure without a deep and detail understanding of the system, especially of the design code for the system due to the particularity of its application.
