: This photograph shows the dustcatcher and washer of one of the Youngstown Sheet and Tube Company's Campbell Works' blast furnaces, East Youngstown, Ohio, ca. 1920-1929. Early furnaces recycled untreated waste gas without removing the dust. This resulted in clogged combustion chambers, requiring workers to manually clean them. This was a time-consuming and dangerous job. Advances in treating waste gas included wet (water) spray washers, dry washers, and electrostatic precipitators, all used to remove more of the coarse and finer particles. View on Ohio Memory.
