[Gasification] Small scale power plants?

[Phil Marsh]

Dear Dr. Reed:

 

Why is charcoal not just a specific type of biocoal? (as in biocoal made from wood) Or are you specifically  saying biocoal is a term only used to describe a product that is torrefied as opposed to fully carbonized as a standard version of charcoal would be?

Biocoal isNOT charcoal!  It contains 80% of the energy in the original wood, but is friable, easily compressed, briquettes or fired as a powder in utility boilers by itself or as an aid to better combustion of powdered coal.

Hi Kenny,

 

You ask:


Is anyone aware of a US commercial producer of small-scale, solid-fuel (bio-coal fired) power plants in the 1 to 20 MW range?

Please define your version of bio-coal, as it can have differing interpretations. It suggests charcoal, if so, one might expect for you to consider a number of options. Tell us more. because there is a huge gap between raw and "pre-charred" fuel gasification. Your range of outputs stretch credibility to supply a pre-carbonized fuel for 20MWe, so what is the direction of your enquiry?  Possibly you are researching the capabilities of the technology, but 1-20MWe is rather big when discussing biomass gasification systems. You might also comment on the end use of the gas, boiler of engine power generation? 

 

This forum has an affinity with discussing these issues, because the future needs what we may be able to do, given the right challenges, and your question should trigger off comment from the accumulated expertise.

 

Doug Williams,

Fluidyne.
