“…In case of a deep-seated fire, the high temperature inside the porous materials due to the fire is maintained for a long time, so the penetration performance of the water used for extinguishing the fire should be excellent and should be kept on the fire for a long time (National Fire Protection Association 2005). Therefore, it is important to cope effectively with fire extinguishing by changing the physical and chemical properties of fire water through the addition of wetting agents (Kim and Rie 2015). Torero and Fernandez-Pello (1995), Palmer (1957), and Kim and Rie (2013) focused on the implementation of deep-seated fires and the transfer rate.…”

As biomass has become increasingly important, wood pellets are becoming more widely used, and the storage of wood flour, which is the raw material of wood pellets, has become inevitable. The purpose of this study was to reduce the economic losses from fires during storage of porous combustible materials. To achieve this purpose, the authors analyzed and compared the wood flour loss rate between the use of water and the use of wetting agents to extinguish a deep-seated fire through a scale model experiment. To do this, the authors measured the penetration amount of the water and dilute solutions of wetting agent, the weight change of the wood flour holder, and the emissions on a real time basis when that spray amount was the same. Furthermore, the authors analyzed the calorific value and combustion gas to examine the reusability of the wood flour with the added wetting agent. This study quantitatively demonstrated that the active use of wetting agents in wood flour storage fires dramatically reduced the fire loss rate of raw materials and resulted in early fire extinguishing, which minimizes companies' economic loss.
