>>Although the dazzling blue flame is but the revealing icing on your linear
>> gasifier cake. I have a question about it. Did InstrumenTom measure its
>> exhaust? Numbers?
>
> The free air flare was not measured, as to freaky for emission measuring.
> The emissions from the Cyclomix burner and heat exchanger were measured, and
> as Tom Miles has indicated, he will post them when back in the office.

>>>"With all gas going to the flare stack, this flow of 147 scft/min made an
>>> impressive flare roughly 2m high. In this mode, considerable information
>>> is obtained from the flare, especially the >>presence of carbon blacks,
>>> or tars, which contaminate the feathery ends of the outer edges."
>
>>When I see changes in the feathery ends of the outer edges, I'm inclined to
>> think that it is from the formation of compounds formed within an oxygen
>> starved portion of the flame.
>
> I'm sure that I have covered this subject previously, but if the gas and air
> are not perfectly mixed before the point of ignition, then you will have the
> CO reverting back to carbon and CO2 inside the high temperature flare which
> is over 500C. This will show up as red tips when the carbon reaches the
> outer free oxygen.
>
>>If black carbons or tars where carried over from the gasifier might you not
>> see them glowing lower down in the flame as well?
>
> That is correct, but the flare behaviour changes depending if the gas is hot
> or cold. Cold gas can spit condensate and tar if present, making sparkly
> like flares in the flame, while hot gas will just radiate hotter (than a
> clean gas), with a sting attached to it if you stand close. You also need to
> know how well the gas is filtered for solid content, because carbon blacks
> will show up adding redness inside the flare, and higher radiation even if
> tar free.
>
>>Can you make the flare flame tips change colour by pushing it rich?
>
> The only way you can test this is to slow the gas flow right down so that it
> does not blow off the end of the pipe. A lazy gas only flare in our case, is
> still blue, but one might see a change in the tips if watching closely. Our
> Cyclomix burner in the heat exchanger, can be run rich to give you a CO
> emission, but no easy way to see in the turbulent flame, if any change of
> colour takes place.

>>Thanks for posting the report.
