[Gasification] Tar on inlet valves

[Oscar Jimenez]

Hi...!!!

...my modest knowledge on gasification has told me that the fight in
getting tar free producer gas is gained in the gasifier itself.
Correctly understanding the mechanism happening inside the gasifier and
controlling accordingly main parameters, can ensure the best gas quality
in reactor output. 

Kindest regards.

Oscar.

Hi

If the tar residue that builds up in the vacuum of the inlet manifold of

engines running on producer gas was subject to the heat of exhaust gas, 
would it burn away or turn to something harder and even more of a
problem.

I got to thinking about this and wondered if possible to have a
'cleaning' 
mode for the engine where some of the hot exhaust gas was recycled into
the 
inlet chamber, mixed with sufficient 'new' gas to keep the engine
spinning 
whilst it was 'cleaning'. I guess you would need to protect the inlet
from 
actual flame but that is doable with a fine screen.

Prolly just a flakey idea, but then again some flakey ideas have hidden 
legs and can run. Maybe its been tried before. Maybe it simply wouldn't 
work for factors I have missed. Who knows?

Ian
