Pellet stoves require certified double walled venting, normally three or four inches in diameter with a stainless steel interior and galvanized exterior.
The boilers were arranged with the forward boiler venting through the forward funnel, a pair venting through the midships funnel and a single boiler venting through the aft funnel.
In uncollapsed lobate terrain, diffuse hydrothermal venting is typically focused in the depressions within the lobate lavas, which are probably underlain by pillars.
Many chemical production facilities are designed with high-volume emergency venting, a measure to limit the extent of injury and property damage when such accidents occur.
