[Gasification] 5M GASIFIERS

[linvent at aol.com]

Need reference contacts. I was not aware that PRM has done fluidized 
bed systems, but fixed bed only. Fluidized beds are for engineers, not 
projects, they are too complicated to operate, have serious issues with 
feed properties and correct operation, ash separation and removal, and 
other unnecessary complications.

Sincerely,

Interesting  - what is the calorific value of the gas – and how much 
does it vary? Fra: gasification-bounces at lists.bioenergylists.org

 Thomas, See attachments.
Tom------------ Dear Tom: PRME has installed nine (10) PRME Gasifiers 
that are greater than 5.0 meters in diameter.  Oldest have been 
operating around the clock for 16 years. Regards,Ron Bailey 
Sr.rbaileys at prmenergy.comhttp://www.prmenergy.com Thomas, The largest 
diameter updraft gasifiers that have been built in the US are 2 m 
fluidized beds. EPI (now Outotec) and others built them in the 1980s 
when there was a tax incentive for gasification. The same companies 
have built 4-5 m combustors but I don’t know of any gasifiers that 
size. The new syngas gasifiers are intended to be that size but nothing 
has been built.   The plasma enhanced updrafts by AlterNRG (e.g. 
Westinghouse gasifier) in Turkey and India may be that large. Ebara in 
Japan may also have something that large. Tom
