- Abstract
- The thermodynamic cycle of a proposed inert gas generator has been examined over a wide range of design parameters. The cycle consists of air compression, followed by substantially stoichiometric combustion to reduce the oxygen content to nearly zero, and massive pre-turbine injection of water, which, on evaporation, cools the gases to the lowest temperature for which the cycle will operate. After a further temperature drop on passing through a work turbine, which drives the compressor, the inert gases can be ducted to the burning building. The proposal has potential space saving and cost advantages over other experimental inert gas generators.
