[Gasification] Mini Grid Load Following With a Biomass Gasifier

Fri Jul 12 18:11:05 CDT 2013

Tom,

I’ll check on the char/ash value but I think is expected to be about 4% which would be consistent with gasifying a low ash fuel.

Dear Tom and list: 

     Governing is important and part of this can be to use an adjustable air/fuel mixture control. 

    As to my question as to what to do with char, the point was that char as fixed carbon represents a significant amount of the heating value of the feedstock and not gasifying it which requires higher temperature than pyrolysis that produces char, means that the system's efficiency is much lower than if it were gasified. Not converting char has significant reduction in thermal efficiency. Technically, it isn't a gasifier if the carbon conversion

Hi Tom, (And List) 

The work I've done involves much of what is in this thread.

First off, the governor is more important that the gasifier's ability to perform. Myself, I'm using the Woodward "L series " programmable units, they are "all in one" and can be configured for just about anything you can throw at it, even droop, and ramp up.

Because they (Woodward) use a HAL effect sensor on the teeth of the flywheel, the regulation can be set "tight" or "loose" (as needed by the local utility)

The L series meets all the spec's to conform to IEEE power transmission standards of the North American Grid, be it Local or Interstate, interconnection.

Tom,

Burn it or bury it. Burn it to recover the energy as direct heat. Bury it in compost, blend it, or direct use. 

I think the Proton model is based on recovering the char. You’ll have to ask them directly.

Re: Proton Power:

What do you do with the bio-char? I do not want to hear of it's use in agriculture as an economic solution as it has spotty performance, limited market radius and a marketing cost.

The company makes automotive equipment and moved into renewable energy and 

wood heating appliances a few years ago.  

For Proton the first commercial unit is being commissioned a the Wamplers 

Sausage site linked on their site. I think that they have run a 110 kWe 

pilot unit at U Tennessee for a couple of years.

Tom  

I have never heard about the spanner gasifier - do you have a reference? 

The proton system have a lot of very promising claims - where can it be seen 

in reality?

Do you have any references to this gasifier? - and web page?
