It should produce gas like this. High H2 and Ch3, CO. Notice Vac Gauges after the filter box and beore the condenser. Suction is at the end then goes to 1 micro filter and no tar. Runs a Waukasha 250 ND aspirated engine generator. --- On Sun, 7/25/10, Brian and Cara Paasch <[email protected]> wrote: From: Brian and Cara Paasch <[email protected]> Subject: Re: [Gasification] Can't get to blue flare [StephenM] To: "Discussion of biomass pyrolysis and gasification" <[email protected]> Date: Sunday, July 25, 2010, 4:30 PM On Jul 25, 2010, at 5:01 PM, Stephen Maupin wrote: > The problem is not your primary gasification air; it is your secondary > combustion air in the flare nozzle itself.

Ah-HA! I thought this might be one of the issues! (See my comments to GregM.) YES, I will definitely work on this! -brian > > --- On Sat, 7/24/10, Brian and Cara Paasch <[email protected]> wrote: > > From: Brian and Cara Paasch <[email protected]> > Subject: [Gasification] Can't get to blue flare > To: "Discussion of biomass pyrolysis and gasification" > <[email protected]> > Date: Saturday, July 24, 2010, 9:08 PM > > Hi all, > > We recently started testing our downdraft gasifier.
