Calculation method for water spray volume in flue gas quench tower
Thread Content
I’m a beginner; please advise me! Thank you so much! I want to build a flue gas quenching tower, and the water sprayed inside the tower must not remain there; it needs to evaporate completely and be carried away with the flue gas. Given conditions: Assume the diameter of the spray tower is 1.5 meters ； The spray water temperature is calculated at 30°C ； Flue gas volume: 5000 Nm³/h ； Inlet temperature 900℃ ； The required outlet temperature is 200°C, but the composition and concentration of the flue gas are unknown. I’m not sure if it’s possible to calculate the amount of water needed for spraying. Additionally, I think the height of the spray tower is related to the heat exchange time; should the height of the spray tower be assumed as some value (for example, 2 meters)?
Why isn’t anyone answering? Is it still the case that the components can’t be calculated at all?

1. Spraying water volume: 1.8 T/H. (Flue gas volume: 5000 Nm3/h, inlet temperature: 900℃ ； The required export temperature is 200°C and the water temperature is 30°C. 2) The diameter is 1.5 m, the flue gas flow rate is 1.973 m/s, and the maximum size of particles that can be evaporated is 540 μm.
