Snip ( note this is with "A" suffix on patent number)
"We do not understand fully the physics of the action that takes place within the burner, but it is our belief that the high velocity of movement through the burner and the high temperature of the superheated steam causes the water molecules in the steam to break down into their hydrogen and oxygen atoms which aids hydrogenation of the fuel by combining the hydrogen atoms with the carbon atoms of the fuel and utilizing the oxygen to aid combustion.""
End snip


Also this patent "2863499 "A"
Mentions minimum 50% less oil
Much cleaner and cooler ( and smaller outlet)
1958 ?

Lots to look through...
Thanks
BTW
If Original poster here wishes ( prefers adhering to low temp thermolysis of water topic ?


Another thread might be needed ?
Or we could use one of your old threads ( water fuel ?

Edit for comment below
Furnace is claimed (Russ wrote previous page ) to run on water thermolysis ( no oil) after certain point .
Also Lanca forwarded a link ( have to look through a bit more)

Hello colleagues!
I assume that the high-temperature addition of water to carbon fuels is not relevant to this topic.
Probably, when burning fuel with water, more heated gas is obtained, but at a lower temperature. When fuel is burned without water, less gas is produced, but at a higher temperature. Heat transfer from a larger volume of gas to the consumer looks more efficient.
Example:
The efficiency of the steam locomotive is only 6%.
If we somehow increase the efficiency of heat transfer from the fire to the boiler by 2 times, then the overall efficiency is likely to be 12% or less.
But where is free energy or overunity?

Sorry for off topic ( a bit ?)
So many experiments in this thread !

Not so long ago, I did some experiments to produce hydrogen using ultrasound.
For example:
- suspension of zeolite in water and ultrasound 15 kHz
- suspension of zeolite in water and ultrasound 15 kHz together with electric field 50 MHz
- suspension of zeolite in water and ultrasound 15 kHz, together with electric field 50 MHz and direct current electrolysis

- suspension of zeolite in water and ultrasound 22 kHz
- suspension of zeolite in water and ultrasound 22 kHz together with electric field 50 MHz
- suspension of zeolite in water and ultrasound 22 kHz, together with electric field 50 MHz and direct current electrolysis

- suspension of zeolite in water and ultrasound 1.6 MHz
- suspension of zeolite in water and ultrasound 1.6 MHz, together with electric field 50 MHz
- suspension of zeolite in water and ultrasound 1.6 MHz, together with electric field 50 MHz and direct current electrolysis

Unfortunately, in my experiments, the yield of hydrogen in all cases was very insignificant, or additional factors, ultrasound and radio frequency, had little effect.

A very small yield of hydrogen was observed in the lowest frequency version of 15 kHz. It does not depend on other factors. But this needs to be verified. Practically not useful.

At higher ultrasonic frequencies, the hydrogen yield was near zero. With additional electrolysis by direct current, the influence of ultrasound or high-frequency electric field was not noticed.

Exception:
- a slight increase in the yield of hydrogen due to heating of the liquid during electrolysis with direct current. The current also increases when the electrolyte is heated.

Visible issue:
- dispersed particles of zeolite or lime in water strongly reduce ultrasonic cavitation.

Using a of a small mechanical single-cylinder air pump to create dynamically changes of pressure and vacuum also did not give positive results.

Do not forget, the static version, described in the topic, is quite efficient:

Not overunity, but working system.

I suppose that a large range of dynamic changes in pressure and temperature is needed.

unexpected formation of hydrogen by sonication of catalytic test reactions containing water–alcohol mixtures...

The current report is based on our observation of irreproducible hydrogen evolution data during screening studies of heterogeneous metal oxide semiconductor HER studies. We noted that during sample preparation, our samples were sonicated for a few minutes in deaerated H₂O/alcohol (8:2, v/v) (alcohol = ethanol or methanol) to ensure homogeneous dispersion. While analyzing the possible sources of error, we performed a blank reference experiment where the pure, catalyst-free solvent was sonicated (but not irradiated), and we observed the formation of hydrogen by headspace gas chromatography. We followed the hydrogen evolution of this sample over time...After ruling out any other source of hydrogen (e.g., glassware contamination, GC malfunction, etc.), the only remaining explanation was that H₂ is formed by sonication. This was supported by literature analysis, which showed that there are a few reports discussing the phenomenon; however, there are no systematic studies of the amounts of hydrogen produced depending on the sonication conditions.

...We have mentioned several times that we note an increase of hydrogen concentration in the headspace of the reaction vessel even after sonication has finished;... In more detail, we have noted that if the mixture is stirred after sonication, the amount of hydrogen in the headspace increases quickly and stabilizes after ∼2 h ... When the mixtures are not stirred, the hydrogen concentration in the gas phase increases at much smaller rates and follows a linear trend, which does not reach a plateau even after 7 h ... To the best of our knowledge, this "delayed sonication effect" has not been reported yet. Based on our initial experiments, we suggest that this is due to slow (without stirring) or fast (with stirring) diffusion of hydrogen from the liquid to the gas phase.
