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

Cyrille,

Thanks. Viessman makes good boilers. In their "Wood Combustion Systems"
brochure (on the site you linked) Viessman shows an (Mawera FSR) 8000 kW
thermal oil boiler with a 1000 kW ORC system. At the time that I discussed
this with them in April of last year they had a demonstration in their
factory but no commercial units. 

Turboden/Pratt Whitney has more than 200 ORC units operating, or in
construction. The thermal oil boiler could of course be fired by a gasifier.
The challenge is what to do with the waste heat. A 2 MWe ORC will exhaust 14
GJ/h of heat (~14 MMBtuh). It is probably most suited to industrial or
institutional use.    

Tom

You might add on your list:

They have some commercial units in operation.
They also have an interesting stirling engine for micro-CHP, but so far NG
based only.

I am sure this price level is achieveable - BUT BUT BUT - there is a major
challege that must be overcommed. 

You need some where you can have 5-10 similar gasifiers operating for 10 of
thousans of hours each with in reachable distance from their "parent (s)"
and this alone needs 50 - 100 mio $ on top of the market price for the
electricity - and it is possible to maintain a stable and bright and not
religious brain capacity for a decade or two.

On top of that you need to start with a good idea and that is where most
principles fail.
And what does that mean? 
Not too complex - with a potential to handle the challenges that will come
in an ECONOMICALLY COMPETITIVE way!!!

Examples - Vølund - Nexterra - CFBs-Repotec and this type of gasifiers will
alvays have the challenge og tar/perticle gas handling issues - personally I
believe it is too complex to handle in a competitive way. 
FCC - may be large scale - but catalyst and gasifier is a challenge
2-3 stage - Viking - double feuer - TKE - and the likes have high
temperature challenges and reduction challenges and bed stability issues -
variation in gaspermeability etc Stirling show a large drop in efficiency if
upscaled above 50-75 kW thus the biomass handling systems becomes very small
and sensitive.
Entrained flow are very big and needs extensive pretreatment of the fuel. 

Many things will work for some time if nursed properly by the enthusiastic
developers.

Thomas

Thomas,

You seem to be the bearer of good news. 

Can you deliver a (3 stage) gasifier(s) to deliver 2 MWe to a grid in
Alaska? What would you expect the capital and operating costs to be? 

We have a few small communities with electrical loads of 1-2 MWe. Power is
currently supplied from diesel generators for USD $0.44-$0.65/kWh. Good
clean wood chips are available at $40-50% MC and $USD 85-100/dry ton. #2
heating oil costs about $4.40 or about $32/MMBtu (HHV). Most communities
just want to produce power. Heat distribution does not exist but they could
probably sell heat in a small loop for about $20/MMBtu. Is there a future
for gasification in these communities?

Thanks

Tom Miles
