The scavenging valve (15) is then opened and the tap or valve ofthe water supply is also opened automatically by means of a cam andconnections, so that water is sprayed upon the heated iron checker-work(10) and is instantly converted into steam which passes downwards throughthe interior of the regenerator and displacing the remnant of combustion.

The steam now superheated passes along the passage (8) up throughthe column of incandescent fuel in the generator, and in so doing becomesdecomposed into its constituents, hydrogen, carbonic oxide, and othergases being produced. The gases now pass up through the green orraw fuel at the top of the generator and subject it to destructive distilla- GAS PRODUCERS. 7: tion, the hydrocarbon and other vapour thereby hberated mixing withthe gases and passing away with them through the gas outlet pipe (5)to the gas holder.
