[Gasification] 2 MWe Gasifier at University of British Columbia, Vancouver, Canada

[Tom Miles]

Thomas,

Sounds like thinks haven’t changed much since the World Bank gasifier
monitoring project in the 1980s. :-/

Actually there are several operating systems in the world. As you say I
think the percentage of low end gasifiers that are actually working may be
pretty low.  When we get our gasification website back online we'll try to
survey and report on some of these.  (We're under a major overhaul due to
high traffic.)

Any industrial gasifier or boiler is going to have to hit basic targets for
efficiency and reliable operation whatever the targets are: 20-25% fuel to
power (NCV); and,  4,000, 6,000, or 8,000 hours per year. I know of
gasifiers that have difficulty making a few hours a day. You need at least
13 hours per day to make 4,000 hours per year (310 days).  

The target for the UBC gasifier is 7500-8000 hours per year. They achieve
that with their heat units. They operated a 250 kWe gasifier for 3,000
hours. I saw it a couple of years ago at 1,000 hours. There have been many
design changes since then. 

Once the reliability of the 2 MWe system is demonstrated then you can build
6-8 MWe systems where you have significant economies over steam systems. But
you need a good power contract (or savings) and you need a use for waste
heat. We hear that Europe (UK, Italy) is the best place for good power
contracts and high heating costs these days so we should see many
gasification plants being built there.

I agree to your statement - give them some time before we ask too many
questions. 

Concerning you statement about Ankur - in the summer 2010 I visited 13
gasifiers in Srilanka - 5 of them Ankur - none was working when I was there
- they told me that they needed a rebuild of the hot zone every 2-3 weeks. 
I also visited a gasifier from TERI - it have had 2-3 hours operation before
the engine exploded and it was never put back in operation. To me it looked
like they had never build a gasifier before. 
Of the 13 gasifier 3 was in operation - and one producing electricity.

Tom,

We find that the ones that are actually running all seem to be pricy. While
we get estimates and budget quotes for 0.5-1 MWe systems at
$4,000-$6,000/kWe, the ones that are actually running at 2MWe are
$8,000-$10,000/kWe. The exceptions are the Sakata and Ankur gasifiers in
Thailand.
