Hydrothermal Biomass-Fueled Engines

     Depends.
     
     If you are talking about introducing this into the intake stream at 
     the 1500-3200 PSI, then electronic fuel injectors are out. Most, if 
     not all, are designed to operate at around 100psi max before they lock 
     open. There may be special apps available, but I'm not aware of any.
     
     As for what would work, I'd have to say a direct injection type setup 
     like they use on diesel engines. Perhaps you could modify it to 
     electronically control the hydraulics...would be pretty cool :)
     
     Sandia eh? Argonne is a lot better... ;)
     
     TTYL!

Hi All,
     
I'm new on this list,so I hope it works.
     
Retired from Sandia Labs, Several patents and 
many years of working with Thermochemical and 
Hydrothermal Biomass Conversion to support
agriculture (especially fixed power units used for irrigation and power 
generation, and dairy-
feedlot manure disposal.
     
About any form of biomass material,leaves, grass clippings,straw, corn 
stover, dairy and
feedlot manures,can be mixed with water and heated to 550-705 F (1500 to 
3200 psi) in a 5/16" diameter tube used as a heat exchanger in the exhaust 
of an I.C. engine or gas turbine.
     
The water breaks the organic material down to
a combustible mix of H2,CH4,C2H4,CO,CO2 and oxgenated liquids and 
particulate solids.
     
EFI looks like the best approach for getting
this steam-fuel mix into the combustion chambers of the engines.
     
Any thoughts on a EFI layout?
