Hi Gasification Colleagues,

For those of you a little more interested in producer gas from downdraft 
gasifiers that are designed to fuel engines, I have added a section on 
producer gas flares to the Fluidyne Archive<www.fluidynenz.250x.com>

Possibly the first experience most researchers and consultants have with 
gasification,is to see the producer gas burning as a flare. This first 
exposure to making a combustible gas from biomass can be very deceptive, and 
the viewer lead to believe that this burning gas demonstrates it's 
capability to fuel, either engines, or process heat applications.

While producer gas can be so impressively combusted, hot straight out of the 
gasifier, contamination in the gas determines it's quality, and ultimately, 
the mostappropriate end use application. This gas can contain water, char 
dust, carbon blacks, and ash, plus uncracked hydrocarbons, all of which have 
to be removed, if the gas is for engine powered electrical generation.

During Fluidyne projects, we have collected many photos of producer gas 
flares, and flu stack emissions, which combined with certified testing 
procedures, has provided considerable information on the behavior of 
producer gas from it's transition from hot to cold gas. The photos offered 
in the Fluidyne Archive,  are a selection of these test flares, and with 
some thought,can be used as a guide when observing combusting producer gas. 
It should be noted, that cold clean gas does not display the luminosity of 
hot gas, but there can be many variations to what you see depending on gas 
quality.

Observation is still one of the best free tools available, learn how to add 
this to your own knowledge from you own producer gas flares
