Fire Tests of Stairwell-Sprinkler Systems
The effect of water curtain or spray nozzel fire protection of an open stairwell was studied experimentally. The experimental setup includes a three story stairtower with a contiguous first story burn room. The instrumentation used to measure the flow phenomenology resulting from fire sizes up to 4MW/(13.6 million BTU/hr.) with and without sprinkler operation is described. A model of evaporation cooling of the hot fire gases as they pass up through the first to second floor stairwell-sprinkler system component is introduced. Based on this model the data are analyzed and correlated for the purpose of identifying both a cooling and a water usage efficiency for each of the system components that were tested. Application of these measured performance characteristics and their extension to stairwell-sprinkler components of different geometries and configurations are discussed.
