[Gasification] gas quality and engine lifespan?

[Mark Ludlow]

David,

I don't completely understand "dry" in this context. With gasoline it
implies a fuel stream void of aerosols; intake manifolds are often heated
with exhaust gas to ensure this condition. With woodgas I assumed that most
lash-ups incorporate some kind of after-cooler to enhance volumetric
efficiency. How "hot" is hot? Hotter than the compressed fuel/air mix during
ignition.

I'm wondering if the phenomena that Ken is describing is related more to
micro-abrasive particles in the fuel stream(?)

His point was that the HOT, DRY gas would remove lubricants from the walls.
