Competitor’s inner pipe metals for pellet
Corn and other biofuels have higher water content than wood pellets.
When water combines in the ue with elements in corn, such as sulfur,
nitrogen, and phosphorus, the condensation is highly acidic. These
acids cause common pellet chimney vent liners made of 430, 304 and
316 stainless steels, to corrode.
Other manufacturers use these
common metals for venting for corn
and biofuels.
Joint research with OMNI Environmental Services scientically proved Simpson Dura-Vent’s super-
ferritic stainless steel is resistant to corrosion caused by corn ue gases. It is the only safe choice for
venting corn and other biofuel appliances.
AL29-4C, while resistant to corrosion, is not recommended for temperatures at or above 600° F. Chimney
res exceeding 600°F can occur in pellet chimneys as the result of unburned fuel residue collecting in
the chimney. At these temperatures, AL29-4C can become brittle, while Simpson Dura-Vent’s super-
ferritic stainless steel is stable and exceeds AL29-4C’s performance for venting corn and other biofuels.
