Abstract
Firefighting foams delivered through fixed-pipe systems have been used for decades, especially in locations where there are petroleum storage tanks and aircraft hangars. However, the current systems, which incorporate aspirating-type nozzles and blower-type foam generators, have several potential limitations, including poor foam quality due to the use of fire-contaminated air to generate the foam. Current systems are also unable to provide foams with high injection velocity, which is an especially important requirement in the case of high-ceiling storage warehouses and hangars, where the injected foam needs to travel relatively long distances and penetrate fire plumes before reaching the seat of the fire.
