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

[Thomas Koch]

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 regards

Thomas

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

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.
