Hi guys
I want to calculate dew point of H2SO4 in the duct of boiler but I have just amount of So2, Co, Co2, O2.
Is it possible to calculate dew point?
Thank you

That's right. so, I Don't need amount of So3???
I found a diagram for dew point of H2SO4, but this needs amount of H2O and So3.
Thank you again

I read this article exactly. In the first page, there is a diagram need amount of SO3 and H2o, but it is impossible to measured amount of So3 for me. Is there any way for calculate dew point of H2SO4?

The amount of SO2 should be derived directly from the quantity/Sulfur content of the fuel burnt. The same applies for H2O. The rest is straightforward.

I want to get the accurate amount. But it is suitable,too.
what material do you suggest to use in economizer where condensate of H2SO4 occur?
RE: end cold corrosion
Then you could get mixed acids.
In high eff home furnaces that condense the exhaust deliberately they use alloys that are suitable for seawater corrosion resistance.
The superferritic grades are common.

It is good idea, but it is very costly.
is there any Commodious ideas?
Is any coat used? Do you know suitable coat?

There are a number of medium alloy SS grades that have been used to line such structures.
