I am trying to hold down the size of the by-pass damper before a heat recovery unit that I am putting on the exhaust of an engine-generator set.
Does anyone know the industry standard for velocity in the duct for this application?
I am designing a heat recovery system for the exhaust from engine-generator sets. My question is, "what is the appropriate velocity for the duct between the engine and the heat recovery unit?" Engine exhaust appears to be around 12,000 feet per minute at the engine manifold discharge...
