Abstract
A system for preventing and suppressing fires and explosions is provided that fills the ullage spaces in fuel tanks with an inert gas that is generated by the operating system or facility. This insert gas is a combustion gas that is depleted of readily combustible oxygen and that is supplied at a pressure exceeding the ambient and displaces any oxygen in the ullage to a level that inhibits combustion in the fuel tank.
