Inert gas generator (IGG) refers to machinery on board marine product tankers. Inert gas generators consist distinctively of a burning and cooling chamber.
Atmospheric air is burned so that it contains less than 5% oxygen, thereby creating "inert gas". This gas is then delivered to cargo tanks to prevent explosion of flammable cargo.
This generator is sometimes confused with flue gas systems, which draw inert gas from the boiler systems of the ship. Flue gas systems do not have a burner but only "clean" and measure the air before delivering it to the cargo hold.
Famous quotes containing the words inert, gas and/or generator:
“Nothing in education is so astonishing as the amount of ignorance it accumulates in the form of inert facts.”
—Henry Brooks Adams (1838–1918)
“one pale woman all alone,
The daylight kissing her wan hair,
Loitered beneath the gas lamps’ flare,
With lips of flame and heart of stone.”
—Oscar Wilde (1854–1900)
“He admired the terrible recreative power of his memory. It was only with the weakening of this generator whose fecundity diminishes with age that he could hope for his torture to be appeased. But it appeared that the power to make him suffer of one of Odette’s statements seemed exhausted, then one of these statements on which Swann’s spirit had until then not dwelled, an almost new word relayed the others and struck him with new vigor.”
—Marcel Proust (1871–1922)
