From this point it moves altogetherby gravity. The gas leaving the top of the producer passes firstthrough the superheater tower, then through washers, gas tower,gasometer, washing fans, sawdust scrubber and condenser ineach of which impurities are removed and by the time it reachesthe engine it is a clean colorless gas. The process of formingthe gas is, briefly, as follows: A Korting blower of the injector type, the operation of whichis controlled automatically by the gasometer, provides a blast of 168 AMERICAN ENGINEER AND RAILROAD JOURNAL.

This mixture is then con-veyed along the mains to the superheaters, which consist of twotubes forming an annular space through which the air and steampasses. The hot gases from the producer pass down through theinner tube in the opposite direction from the air and steam anda large amount of its heat is transferred to them. From thisthe hot air and steam pass through a similar annular spacearound the producer and downward below the fire bars. The gasafter passing through the superheater goes to a washer havingtwo dashers revolving at a good speed, which throw the watercontained in the washer into a fine spray through which the gaspasses, thereby being cleaned and at the same time giving up alarge amount of heat.
