A Study on Performance of Water Curtain Nozzles for Protection of Wooden Cultural Properties from Forest Fire

This study suggests the water curtain nozzles as the way to protect important wooden cultural properties from an adjacent building fire or a forest fire. They are designed to block off the pyrolysis of timbers which occurs at by forming a water curtain with the flow of water that spouts over a certain pressure from the bottom. The existing water curtain nozzles installed at the following sites were examined: NakSan-sa (Temple) in Gangwon-do (Province) and in Muwisa (Temple) in Jeollanam-do (South Province). As a way to improve and complement the system, this study designed nozzles with covers in order not to disrupt the landscape. Connected pipes are elevated and jet water when they are in use. Possible ways to install the connected elevating pipes to jet water effectively were investigated.
