ICCS boiler PAVE (Pump Water Vapor)

[PAVE]

I ended up finding a pdf econology that shows what this PAVE pump steam
https://www.econologie.com/combustion-en ... -3865.html

blah is an additional heat recuperateur to condense at lower temperature than the temperature back from a boiler Condensation

and as moist smoked out of a boiler contains more energy than it takes to preheat the intake air, humidify the air intake allows to recover a little more heat

it seems to me a very small solution because it involves less than 1% of total return

remains to be seen the effect of the moisture on the combustion quality ... and I'm reading I have not seen any explanation

In fact, a real Water Steam Pump (PAVE) works throughout the heating season with a yield that ranges from 101 to 108% on PCI. These are yields that are only very rarely obtained with condensing boilers under real conditions of use, especially if the boilers are also used to produce domestic hot water, which is very often the case.
So, to summarize, the gains in yields are rather of the order of 5 to 15% ....
With regard to the quality of combustion, the results obtained are a virtual absence of CO and a reduction of NOx emissions by 2 to 3 (sometimes up to 10 mg of NOx by NM3).
In short, you see results far superior to what you imagine.

to burn heavy fuel oil or waste oil I agree that the steam is useful

Besides the first burner for heavy fuel oil for boiler steam it has been spray steam jet! , Initially by ease because when we steam under pressure it is easier to put a jet of steam that another type of pump, then took glimpse the steam had a positive effect on combustion

but with other fuel such as methane or producer gas that burn perfectly without adding anything to what little has used doping water?

I do not agree with this way of presenting water as a solution universselle

in the engine oil, oil also burns perfectly

in diesel, it seems that increasing injection pressure has solved the problem ... what made them disappear aquazole kind solution that were useful especially on some old engine ... and not even all because some old engine diesel is always good combustion

This is not the universal solution, certainly.
It is simply a question of obtaining the best possible performance of all the combustion and the products of combustion .... like the water produced and present in the fumes. There is sensible heat and latent heat unused or not enough in the existing boilers.
The complete cycle makes it possible to use them as much as possible.
In some cases, we obtain fumes at 20 ° C !!! imagine what remains as energy lost in these fumes!
Another consequence of the complete use of this technology (wet combustion: combustion air from 50 to 60 ° C to 100% RH) is to lower the flame temperature ... and therefore a lower production of NOx (from 2 to 3 minus the minimum).

So, still not THE universal solution, but just a certain improvement in performance!

You have an installation with a PAVE to show us, with a balance sheet etc ...?

You have an installation with a PAVE to show us, with a balance sheet etc ...?

I have 4 during startup or end of installation.
Installed powers range from 2 to 3 MW.
Advanced instrumentation must be set up by a research center in a few weeks.
So it will be soon once these manipulations ended.

You have an installation with a PAVE to show us, with a balance sheet etc ...?

A PAVE of new generation has been in use for a few weeks on a property complex located in the Paris region.
The thermal power of the installation is 2 MW.
The results are as follows:

PCI 105% performance
Flue gas temperature: <45 Degrees Celsius
Condenser inlet temperature: ~ 60 degrees Celsius
Condenser outlet temperature: ~ 70 degrees Celsius
It can be seen here that the condenser is operating when the temperature is above the "normal" dew point of conventional combustion with natural gas.

I will post some photos of the installation in a few days.

As expected, here are 2 photos from this installation
