Regarding the chimney issue
Thread Content
Why are chimneys designed to be so tall? What is the reason?
Because typical flue gas still contains residual sulfur dioxide and dust, this reduces pollution in the working environment at higher altitudes
If it is released into the upper atmosphere, it will still pollute the environment
Reduce the concentrations of diluted sulfur dioxide and smoke, and also improve the natural ventilation capacity of the flue.
It’s different; when emissions occur at low altitudes, the concentration of pollutants is very high, and it can easily be deadly. Emissions at high altitudes are different, as the wind carries them away, resulting in lower concentrations and thus less relative hazard.
1: Raising the exhaust outlet helps to disperse pollutants and keep them away from people. 2: Increasing negative pressure facilitates the extraction of smoke gases
Reply to 1# Dugu Bin: The harmful substances in the smoke can be carried to higher altitudes, thereby reducing the resistance on the exhaust fans
The main considerations are the ground-level concentrations of sulfur dioxide and nitrogen oxides. A tall chimney allows for greater dispersion over a larger area, which helps to reduce the ground-level concentrations near the chimney and meets environmental regulations.
1: Raising the outlet height facilitates the dispersion of pollutants. 2: Increasing suction power saves electricity

Considering the concentration at ground level, a taller chimney results in a larger dispersion area, which can reduce the concentration at ground level near the chimney. 2 The chimneys are tall and have strong suction, which facilitates the emission of smoke gases. 3. Environmental protection requirements; if you don’t believe it, try emitting pollutants directly without using a chimney. . .
