Purpose. To conduct full-scale researches to determine the effect of water fire extinguishing solution on the hydraulic head loss in fire extinguishing pipeline and determin the relative effectiveness of the fire-extinguishing sprinkler system at natural firing tests.
Methods. In the work is used the methodology of field tests for studying the relative efficiency of water fire extinguishing agent during fire extinguishing. The research results have been treated by methods of computational mathematics using the software «Microsoft Office».
Findings. The results of experimental studies to determine the effect of specific additives to the water of complex action on the basis of sodium liquid glass Na2SiO3 and potassium carbonate K2CO3 on hydraulic characteristics and the effectiveness of fire extinguishing sprinkler systems are presented. The relative effectiveness of fire extinguishing sprinkler systems filled with investigated extinguishing water solution as compared to the sprinkler system filled with water without any special additives for extinguishing the model Class 13A fire is determined under the similar conditions of full-scale fire tests.
Application field of research. The proposed water fire extinguishing solution is designed for the use in the sprinkler system which is separated from the system of domestic and drinking water supply system.
Conclusions. The efficiency of specific additives to water of complex action on the basis of sodium liquid glass Na2SiO3 and potassium carbonate K2CO3 is proved to reduce hydraulic losses in the fire extinguishing system and improve the efficiency of fire extinguishing.
