A numerical study of some fire scenarios with and without water sprinklers in storehouse fire from the background of engineering was described. The detail computations were determined at three working conditions. Results showed that fire spread speedy in storehouse and smoke descended from the ceiling to floor very fast without water sprinklers; in comparison, under working of water sprinklers in time, fire was under control effectively, and smoke rested on ceiling; if water sprinklers work time-delayed, fire could also be extinguished by the system of water sprinklers, but almost the whole storehouse had been fired, and the stores had been damaged by high temperature and the smoke. By comparing the results of different working conditions, the scientific basis for the design in system of water sprinklers for the same type storehouses, and the importance of good working condition of system of water sprinklers can be seen clearly.
