Calculation of the amount of flue gas condensation water in the condenser of a waste heat boiler
Thread Content
The amount of condensate water calculated using HTRI is 4.14 t/h, and some people say this figure is on the high side. I would like to know how to calculate it specifically. Thank you
It’s not too big, it’s too small. . . Are you manufacturing wet desulfurization flue gas condensers?
Yes, wet flue gas desulfurization. It’s not entirely clear how it’s calculated exactly

If you use air, then you need: 1) the temperature of the air ； 2) Relative humidity of the air ； 3) Air excess factor (usually taken as: 1.05) ； If you are inflating with pure oxygen, free of water ； Water produced by combustion. Natural gas and coal are different: burning coal does not produce water on its own ； Natural gas combustion produces a significant amount of water: C+O2——>CO2 (coal combustion does not produce water); CH4+2O2——>CO2+2H2O (water is generated during natural gas combustion). This is not the case with coal. It contains free moisture in itself, which is carried into the flue gases upon combustion. For example, low-water coal contains about 10% free water. As for how much water will condense, it is necessary to calculate the thermodynamic equilibrium. In short, this issue is not simple. If you use the BoxHeater software, it allows you to select the type of fuel, and it automatically estimates the amount of condensation – it’s quite reliable.
