Likewise, boiler number 3 will discharge more than number 2, and so on. The net effect is that if boiler number 1 is fully loaded, the other boilers are progressively overloaded, the effect worsening nearer to the final off-take. It can be shown that, typically, if boiler number 1 is fully loaded, number 2 will be around 1% overloaded, number 3

The calculation of carbon dioxide concentration in steam

That is, the concentration of carbon dioxide in the steam is 2.0*0.87= 1.74 mg-EQ/l or 1.74*44=76.56 mg/l. To put it simply, if bicarbonates did not decompose in the boiler, then after evaporation their concentration would be 23 mg-EQ/l. But since bicarbonates decompose, a hydrate is formed in the boiler, the amount of which is equivalent to
