[Gasification] combustion of tarry producer gas

[Tom Miles]

Mark,

Nexterra, the newest industrial scale gasifier in North America, is working
on tar reduction for engine applications at their 8 MMBtuh pilot facility in
Kamloops, British Columbia. I suspect, however, that their solution will be
partial oxidation which burns gases to crack tars, not burning tars to
enhance gasification, which I think you are suggesting.
