exhaust fumes

[Agile]

Its byproducts of combustion - carbon monoxide, nitrogen dioxide, water.......

Perhaps thats what Ideal boilers produce?

It could explain why they dont work so well?

 

[WDIK]

saying nope to snb forelahyde is formed on heat exchangers when the flame temp is to low ,
Explain how carbonic acid is formed during this process of combustion if you would

simple...

Carbonic acid, has the formula H2CO3. It is also a name sometimes given to solutions of carbon dioxide in water, which contain small amounts of H2CO3. The salts of carbonic acids are called bicarbonates (or hydrogencarbonates) and carbonates. It is a weak acid.

 

[namsag]

I know what carbonic acid is but it is not an product of combustion ,it is formed by a completly different chemical reaction.

WDIK your name is not far off where you copied your first 2 lines of what carbonic acid is in wikipedia.
So where does it say product of combustion

 

[WDIK]

carbonic acid is formed when carbon dioxide is passed thru water, a major constituant of burning gas is water.

 

[Softus]

Air is 78% nitrogen, so I would expect to find NO2 in there!! Or am I just being stupid?

Not stupid, but badly trained.

Since you've put yourself forward as a representative of Ideal, that's not a good situation.

WDIK as i have already said i know what products of combustion are and what carbonic acid is .
What i have asked you is twice to explain how carbonic acid is formed during the process of methane combustion is this not on wikepedia.

you also say that 5% oxygen is a product of combustion can you show where you get that from

Also by your figures you have managed to achieve more coming out of a reaction than went in
78% Nitrogen
10% co2`
5% Oxygen?
now that adds up to 93% then you say the rest is water well have a proper look at the combustion equation there is twice as much H2O as CO2 so there is another 20% so that adds up to

113% have you found a new way of making something from nothing.


Here is another way for equation to be wrote

1M3 of CH4 + (2M3 of O2 + 8M3 of N) air becomes 1M3 of CO2 + 2M3 of H2O + 8M3 of N

So 11M3 of stuff went in and 11M3 of stuff comes out not 12 not 10 but 11

 

[Agile]

Since all boilers ( with the possible exception of Ideal ) produce both CO² and H²O in their flue gases, then it seems perfectly reasonable that they could combine to form H²CO³ as in boiler condensate for example.

Your also missing it Agile that is not a product of combustion it is a seperate chemical reaction and does not happen during combustion of methane

where is this coming from?

I have said no such thing!

you dont need lessons in either chemistry or combustion, i know that, neither do i.

you are confusing me with SNB.

the title of this thread is

exhaust fumes

all combustion is an exothermic chemical reaction, the bye products being the gas's and compounds that result from that reaction.
where the products are of a sufficiently low temperature, then water will reform as vapour and in the presence of CO2 form weak carbonic acid.

to create carbonic acid all you need to do is percolate CO2 thru water, the valiency bonds are very weak

Dont listen to me then

 

[namsag]

WKID apologises for mixing you up with snb
We could give each other chemistry lessons all day
So now we are talking fumes , put a link to where carbonic acid is formed in a Domestic boiler of this type .
Not industrial , commercial or power stations

 

[Softus]

Dont listen to me then

Thank you for your suggestion, but I have a better solution.

 

[WDIK]

apology accepted

carbonic acid forms so freely, just dip some condense with litmus paper.
even rain contains carbonic acid, thats what disolves limestone and forms caves

How and why solution happens
Simply stated, acidic waters dissolve carbonates. How do these natural waters become acidic?
As water comes in contact with CO2 in the atmosphere and in soils, they combine to make carbonic acid: CO2(gas)+H2O <---> H2CO3 (carbonic acid) or more correctly, because carbonic acid dissociates in water
CO2(gas)+ H2O <--->H3O+ (hydronium ion, the source of acidity) + HCO3- (bicarbonate ion)
Carbonic acid is a weak acid. Given an atmospheric concentration of CO2 of 10-3.5 atmospheres, the expected acidity of rainwater is 5.5. But in realty, it is 4.8.

Thank you for your suggestion, but I have a better solution.

Pray tell lol - look, point is Im still learning about all things boilers etc - so Im good with logic and boiler parts, maybe not so great with system related and other stuff hehehehe

 

[bengasman]

you should have no hinder from your neighbour's boiler.

Is that english?

It actually is English, though the word I was looking for in this context seems to have been: hindrance.
I could not find it, as it was buried under a fair amount of Guinness though I can not guarantee that there were no other brands involved.
