GAS-L: Eductors for gasifiers...

[Reedtb2@cs.com]

Dear Skip et al:

Ejectors (eductos) are described in our "Handbook of Biomass ..Gasifier  .. 
Systems"  on P. 87 and 96.  They can be driven with exhaust gas, nitrogen, 
steam, propane, or air, depending on application.  They are particularly 
useful for handling tarry gases in experimental situations, for gasifier 
startup etc.  

Yours truly,                    TOM REED

 After building several steam atomizers for liquid fuels, I think I have
 worked out the quirks on low flow (under 1gpm) systems.  I also think I have
 a real good handle on the stack eductors which work of steam and some give
 volume while others can give lower gas flow but high vacuum.
 
 All said...why couldn't  a gassifier utilize a high vacuum eductor and
 'draw' the gasses through.  You would also have a source of cooling on the
 incoming water/steam.  Best of all, there is no moving parts to corrode or
 wear out.
 
 Question is: could the gassification temp. be lowered if chamber pressure
 was lowered to say 23hg?  It surely would assist in the removal of moisture
 from the wood.  Perhaps, tars could either be reduced or localized?
