Hello
I am Erasmus student in a Chemical university in Prague and a teacher give us subjects that we are not able to solve (because we are not really students of chemistry)
This week he gave us this problem
what is the mixing ratio of sulfur dioxide in flue gas (% volume) ?
Fuel is heating oil with 2,5% (by mass) of sulfur.In the fuel to eath atom of carbon there are two atoms of hydrogen
Expect
The air excess λ =1,2
All carbon from the fuel is burnt to carbon dioxide
All hydrogen from fuel is burnt to water
All sulfur from the fuel is burnt to sulfur dioxide The water formed by combustion stays in gas state
3% of total sulfur is chemically bound in ash
the air to burner contains 20,9% oxygen ang 80,1% inert gasses (nitrogen)
so2=
ppm
Can somebody help me
my first problem is what is the equation from the left side
thank you
