[Gasification] Using LPG/natural gas burners with producer gas

[David Coote]

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?

Regards

David

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.
