Another thing of interest is all the lint clogging the screen thereby effectively reducing the flow capacity severely while placing combustibles (lint) in the duct. Just add heat because you have the fuel and oxygen. If this duct sees higher temps from adverse pressure effects such as flow reversals, the lint begins to pyrolize and thus have a lower ignition temp.

Dale, you shouldn't be showing off your own house.

While Dale has these pics up, can anybody draw any conclusions on how these people burn fires based on the pics presented?
