Picking up on Doug's comment below about variation from normal analysis
leads to a few questions.
The methanation project at Gussing managed to produce gas of a quality
suitable for adding to the natural gas grid. There is a similar
initiative underway in Finland at a commercial scale. But these are
large well funded plants. For the moment its difficult to see
methanation technology in use at small gasifier scale.
I've just been doing some work comparing the costs of thermal energy
from biomass systems against LPG/natural gas. A number of industry
references pointed out the importance of correctly configuring burners
to use gas of different calorific values. How is this best achieved with
producer gas where the calorific values can vary quite a bit?

Hi Tom R. and Gasification Colleagues,
[snip]
What we don't see spelt out about producer gas, is that it's variations away from what we
might call "normal analysis" is infinite, and how that affects the combustion
chemistry, engine operation and/or it's componentry life. That we might choose to fiddle
with older basic slow speed engines to make them perform better for basic electrical and
mechanical power, these modern high speed engines place real challenge on the gas making
consistency.
Gasification remains for me one of the most challenging technologies that have
crossed my path, and if I think for one minute I have it by the tail, the other
end will bite me given the right conditions.
Onwards as Tom R. suggests.
Doug Williams,
Fluidyne...
