Nice, pricey system.

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: [email protected]

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
