Formula calculation buffer gas bottle

[papy49]

Hello
here is my question I have a formula to calculate the capacity of a gas buffer tank of which I give the summary boiler power 120000kal / h pcj 8600 flow 120/86 = 14kg / h 14 * 2/1000 = 28litres
diameter 219> s = 0.037 * 80cm = 2.96.
what does pcj mean because I am very curious and if possible to explain myself the totality of this formula.
it was a heating engineer who gave it to me. He explained it to me a long time ago.
good afternoon everyone and thank you in advance.

and me, I would be very curious to understand what you call a "gas buffer cylinder"?

a gas buffer outlet is a outlet upstream of the boiler, the gas arrives on it and the outlet on the boiler burner to avoid loss of power to the burner.

Is that so ? Thank you . Never seen, yet I frequent a lot of cellars. But it must be said that with us the installation of gas tank CC are quite rare. I guess that's where we plug them in?

re
I myself may be badly explain that I do not have a gas tank but a bottle that we put next to the boiler and for nat.pour gas.
these to have a reserve when the burner restarts.

In principle, it is a bit the opposite of the hydraulic ram. I have heard of this device as a "bottle".
Its role is to accumulate sufficient volume so that the pressure does not drop when the burner starts, while the gas column is set in motion.

the main thing is missing: at what pressure does it work?

in individuals with gas at low pressure, therefore very close to atmospheric paression, a rigid tank does not accumulate anything at all and is useless: we can consider the gas as incompressible


for industrial installations where the gas is delivered at higher pressure a tank can sometimes be useful

operating pressure between 16 and 20g

16 or 20g is a mass not a pressure

to express a pressure you need grams per certain surface area

I never try to guess an incomplete unit, it leads to the worst mistakes: I prefer to question until the one who asks gives the whole info

king.
I'm talking about the pressure of the nat gas at the outlet of the meter for the particular
and I think it should be 20 or 23 grams now.
