Dear Tom
I would agree with you that a Top Lit Updraft Gasifier, operated in a batch
mode would be great for producing "Heating Grade Gas" (HGG), when there was a
desire to also produce charcoal. However, if Masi was interested in maximum
use of the corncobs for producing HGG, then a "top lit gasifier system" would
not appear to be the best approach, because the charcoal left over would be
undesirable. Additionally, there is the problem of a "batch operation."
If Masi wanted a gasifier system to produce a woodgas suitable for powering an
Internal Combustion engine, I cannot see how the Top Lit Gasifier could
possibly produce an Engine Grade Gas. (EGG) I would suggest that it would have
excessive tar, that would make it useless for fuelling an IC Engine.
Additionally, there is the inherent problem of the batch nature of the TLUD
gasifier.
As I see it:
1: The TLUD gasifier is great for use with a close coupled burner system, where
there is a wish to produce a residual charcoal, and where batch operation is
acceptable.
2: A TLUD gasifier is not appropriate for producing Engine Grade Gas, because
of an unacceptably high tar content.
3: A TLUD gasifier is not appropriate unless it is desired to produce a
charcoal by-product.
I might be missing something, but do you know of any way that a TLUD can
produce engine Grade Gas?
Best wishes,
Kevin
