Wet combustion: explanations by Rémi Guillet

[Christophe]

Uh no it's when you inject a lot of water precisely: you use only the CP of water and no thermolysis.

I spoke in the case of doping (engine or boiler).

Hello

A lot of industrial oil furnace burner in rolling mills
uses burners whose atomization is done with steam
when using compressed air for start-up, there is a differrence in the whiter flame.
Steam when the burner is used at low power the flame is blue as natural gas.

When used at full capacity the flame becomes more yellow

Bonjour à tous

Rémi Guillet's text appeals to me. I ordered his book
"From the hygrometric diagram of combustion to water vapor pumps: a new look at combustion and its energy applications". I will keep you posted.

This is good, I was trying my experiments to make hot engine air swallow, it is certainly the easiest way to increase the amount of water to be swallowed by the engine without too much danger .

Intersting, the flame is blue to what percentage fuel / water?

Because if it is yellow, it is that the dosage is too weak

Some info on the subject that I found (they are in the .pdf quoted in the 1er post):

-The 2 books by Rémi Guillet "Hygrometric diagram of combustion with steam pumps" and "Wet Way Combustion: Energy Efficiency, Environmental Protection", published by Elsevier, respectively in 1998 and 2000 and now unavailable at the publisher can be obtained by contacting the author directly

-The thesis on "wet combustion and its performance" (UHP1- Nancy 2002) by the same author can be obtained by contacting ANRT (PhD Reproduction Workshop) -BP 47-38040 Grenoble.

Good who gets stuck?

Now I'm here for the steam injection:


perfect combustion reaction GO (nitrogen is not present)
C2H16 34 + = 49 2 O32 CO2 + 34 H2O

adding water vapor first (Important) of the combustion cycle spectacular pollution

in fact it is these two arch-known reactions that explain these results:
H2O + C = CO + H2 : the incandescent soot particles (the "bad burns") react with the water vapor, this requires a temperature above 950 ° C and if possible below 1300 ° C, hence the difficulties encountered by our amateur testers on all these systems

CO + H2O <> CO2 + H2 : CO from the first reaction and imperfect combustion reacts with steam to supply hydrogen; as the T ° must be greater than 950 ° C otherwise there will be excess CO

H2+2O2<>2H2O The hydrogen produced by the first two reactions contributes to the destruction of the unburnt, to maintain the explosion longer and thus to increase the yield.

Basically, unburned are converted into energy before becoming


And as Christophe assumes, it is possible that the C from the fuel also react during the reaction

IMPORTANT NOTE:
the fact is also that, since the water vapor is injected at the beginning of the combustion cycle, the available C which has not yet reacted (and which would have reacted in the normal cycle) does not have the time to finish completely. its reaction which allows the water vapor already present to act according to the first reaction

the advantage is also that if CO is produced during the reaction, it will be immediately transformed !!

[Christophe]

It is even certain that the C of the fuel influences at least indirectly because the soot is only the "residues" of the C of the fuel.

But energetically I think that the soot is far too weak (what is the current standard in soot gr / km?) to make a significant contribution ... unless we create "more" during combustion with humid air to better convert them into H2 afterwards?

In short, again, it's hard to decide what exactly is happening and especially in what order!

Moreover, even the engine manufacturers do not know exactly how the kinetics of combustion precisely! (Which hydrocarbon chain breaks in 1er?)!

One thing is certain and certain: with a water doping (autogenous or not) there is (a lot) less soot (for the reason that you explain with the equations), this is the common denominator of ALL GP montages : it smokes less!

Particle filters will clog much less with the benefits it gives!

This alone is a huge gain for engine manufacturers and this excuses them all the less for "boycotting" this "technology"!

Strip of his **** ...

In short, let's leave them in their "corner".

All this will be one of the 1ere publication of the association to the press! Banzai !!

[Capt_Maloche]

Reread what I added in blue

indeed, cart thanks to a controlled reinjection, no more need of particulate filters and catalytic converters !! gain in weight and immediate consumption

[Christophe]

Ben of the to remove the pot and FAP, uh do not exaggerate too Maloche!

If already the FAP did not clog up more it would be a huge technological victory!

[Capt_Maloche]

It's one, and I'm serious

many of us have already checked on this forum with approximate settings
