Abstract
An apparatus for suppressing a fire comprises a gas generator containing a propellant and a fire suppressant as a mixture of compacted powders. The average diameter of a fire suppressant particle is larger than the average diameter of a propellant particle and the larger fire suppressant particles form discrete cooling sites that do not dramatically reduce the propellant burn rate.
