Thomas, Mark, I think it is best to let them run for a year and work 
out the kinks before we second guess efficiencies. Let’s hope they can 
get the kinds of run time and capacity factors that Babcock Volund and 
Repotec report.I am sure they will report once they are running 
smoothly. I’m interested to see where they are a year from now in 
operation and maintenance costs, efficiencies and overall reliability. 
Judging from their other plants and from what I see I would say their 
prospects are good.  This is an installation that is only a few miles 
 from the Nexterra head office and not far from similar gasifiers that 
Nexterra has  have at a local paper mill. As Thomas would say, the baby 
is not too far from the parents so when it cries they can respond 
quickly. And they know where to find good quality, local, fuel.  The 
heat output is larger than stated on their website. I haven’t discussed 
this with them but they did say that the heat load is the primary 
benefit of the system. Power generation is secondary. The university 
pays much more for natural gas than we would pay in Oregon at 
industrial rates. Plus the province has a carbon tax. So heating with 
wood is desirable. Perhaps for this they increased the size of the 
boiler.  If I remember correctly the jacket water dries the fuel (in a 
Stella down flow belt dryer). The boiler is fed with engine exhaust and 
directly with gas from the gasifier. The gasifier can drive either 
heat, power or both.  Tom    From:

 Hi Tom Vonderfull to hear that good quality small scale gasification 
systems are being build.  One of the challenges of small scale 
gasification systems are the low total efficiency.   As I can read from 
their homepage it is a 2 MWel system that is also producing 9000 pound 
steam/hour and a total efficiency og 65 %  That gives a total fuel 
input of 7,5-8 MJ/s and 25-26 % electric efficiency and a total loss of 
2,5-3 MJ/s. Is it possible to say where these losses occur? Best

 Dear Tom,Could you please clarify the steam output? (The link states 
9,000pph.) Is this from a direct-fired boiler or heat recovery? If heat 
recovery, is it from both gas conditioning and exhaust heat 
recovery?Best, Mark From: gasification-bounces at lists.bioenergylists.org

 This week I had the privilege of visiting the new 2 MWe wood fired 
gasifier at University of British Columbia in Vancouver, British 
Columbia. They are just finishing construction and will start up the 
Jenbacher engine in mid-July. It looks like a very well-engineered and 
well-built installation from fuel receiving right through the gasifier, 
gas cleaning, engine, boiler and heat exchange. The system will supply 
just under 2 MWe net to the campus and 20,0000 pph steam to the campus 
heating system. It is nice to have an installation of this quality and 
capacity in North America.  See www.nexterra.ca Tom
