[Stoves] Sasol Fixed Bed Dry Bottom Gasification Technology

Wed Aug 24 12:50:55 CDT 2011

Dear John

Thanks for popping up. Long time no see. How is the stove multiplication
project going?

Given that steam is added in this gasification process, is it not reasonable
to assume that wet coal (like lignite etc) will produce better combustion
that regular ‘hard’ coal in a small, air restricted environment?

I was thinking today that we should challenge the notion that the water gas
shift reaction is not taking place in lignite stoves. The negative position
was taken by a professor friend who felt there was no chance it could
happen. It seems to me there is little difference between what SASOL is
doing and what takes place in a Mongolian stove where we sometimes get huge
H2 readings (H2(EF) = 12,000 to 15,000 ppm) in the chimney when the burn is
not going well.

If it is working already, why not enhance it? Coal with built-in water for
the steaming part of gasification. 

You da man
what’d you say??

Regards

Crispin

Crispin,

I think the article is right.  “Caking fine coal”  it does not work well in
gasifiers.  The coal is totally gasified to ash.

John.

Dear Friends

I think they mean coking coal not ‘caking coal’.  Fixed bed dry bottom
(FBDB) gasifiers are useful for thinking about how to make a pyrolysing
stove or a coal burner. Basically the idea is to avoid melting the ash.

A relevant group of articles is at
http://worldwidescience.org/topicpages/s/sasol-lurgi+fbdb+gasifier.html 

Once fuels are pelletized and fed continuously, the description in the
second article is relevant: continuous operation with no ash clearing
hassles. Think: space heating and institutional stoves.

ACI is delighted to announce Pauli Baumann of Sasol Technology as a
confirmed speaker, delivering an overview of their recent technology
improvements and project status.  

Sasol is currently deploying four additional Sasol® FBDB™ gasifiers at its
Synfuels facility which will bring the total installed base to eighty-four
(84) gasifiers.  Another major 
milestone has been the commercial scale demonstration of an advanced Coal
Stirrer-Distributor (“CSD™”) for the processing of caking coal as part of
the largest test 
campaign on the Sasol Test Gasifier to date
