[Gasification] FOUR STAGE, FLUIDIZED BED GASIFICATION PROCESS MINIMIZES NOX

[Tom Miles]

Tom,
 
The staging is clearly decribed in the paper and shown in the graph. They
dealt witht he alkali problems and the NOx. In all their performance was
good. That plant had a very interesting history. Ultimately I think they had
too many problems with the "Carver Greenfield" dewatering process.

Dear Dr. Miles,
     In your caption, "FOUR STAGE" appears to mean that there are 4 stages
to the fluidized bed gasification process which would be interesting. The
only published work on that was FMC's coal system in the 70's, but I think
that was all fixed bed stages. What does staged combustion mean? 
     More interesting is what happened after 1996? Why were they not used?
Los Angeles the last I heard was shipping their biosolids to Kern County
(Bakersfield) because they ran out of land to apply it in their area. Kern
County applied a tax to their trucks because of the damage so many trucks
were doing to the roads.
