IIRC, Earl gave a fairly detailed description a few months ago.*  They work something
like the cone-shaped cyclones that I used to see at sawmills, which separate sawdust
out of the air by means of a swirling action, and were apparently applied to the K-36's and
K-37's at some point to replace the angled screens of the old 'Master Mechanics front ends'
as a much more efficient means of keeping large cinders from exhausting out the stacks.

My Dad - in addition to developing the Polytone drilling-mud additive that maybe/probably was one of the commodities shipped from Alamosa to Farmington on the D&RGW narrow gauge - also marketed a heavy-duty cyclone to the oil drilling industry that separated the sand out of drilling mud. These cyclone de-sanders greatly reducing the wear-and-tear on the pumps used to force the mud down the drill pipe to bring the tailings up from the bottom of the hole by separating out the highly abrasive fine sand before the mud flowed back into the pumps - essentially by taking advantage of the same principal as the Andersson Cyclone front ends installed in the locomotive smokeboxes.
