At one point in my grandfather Renie Wilson’s career at the Ávalos smelter, he worked in the baghouse. Below is a March 5, 1945 report detailing work on the baghouse. I know nothing of the smelting process but after reading this report I felt I needed to at least understand what a baghouse is! Maybe you’ll be interested in reading a little background information as well.
From the 1916 edition of Modern Shop Practice edited by Howard Monroe Raymond, “Flue dust is recovered in large brick or steel chambers and ducts, the latter made long enough so that the gases will be cool enough to enter safely the cotton or woolen bags at the bag house. Bag houses are wooden, iron, or brick structures surrounding enough long porous bags to filter the solid particles from whatever gas may have to be treated. The cellar compartments receive the fume-laden gases and the collected lead fume falls down into the same cellar whenever the bags above are shaken. The top of the cellar is the floor of the bag room; this floor is hardly more than a support for row upon row of iron thimbles about which the bottom ends of the bags may be tied. The main chamber of the bag house is hung thickly with bags 30 feet long and 18 inches in diameter, which bags may be of cotton or of woolen fabric. Such a bag room may contain from 100 to 1,000, or more, bags; large plants commonly put partitions through so that one section may be repaired or cleaned while the others carry the load.”
