Abstract : The object of the research was to develop and test methods which will allow high expansion foam production when the only air available to the foam generating nozzle is contaminated from a combustion environment. The significant results of the current work can be briefly summarized as follows: (1) High expansion foam will not efficiently form if the inlet air temperature to the foam generator exceeds 212F. (2) Water spray scrubbing successfully cools inlet air from 600F to 100F, a temperature at which foam is efficiently produced. (3) The foam stabilization chemicals all affected increased foam made with smoke contaminated air. (4) Scaling considerations indicate that scrubbing systems compatible with existing foam generators are feasible. (Author)
