The issue of exhaust gas velocity in coke oven chimneys
Thread Content
Is the flow velocity of the exhaust gas the same at a certain circular cross-section at a specific height of the large chimney of the coke oven? Is it that the speed in the center is fast while the speed at the periphery is slow? Or the other way around? How is the total amount of exhaust gas from coke ovens measured? Are there specific methods and standards? Thank you
At the outlet of the chimney, the exhaust gas flows rapidly in the center while the flow velocity is slower around the edges.
Refer to HJ/T75, HJ/T76, and HJ/T 397 to see if they are useful
In a circular channel, the flow velocity is highest at the center and lowest at the edges, with the velocity decreasing from the center to the edges in a standard parabolic pattern.
Please refer to the section on fluid flow in Principles of Chemical Engineering; the textbook provides detailed mathematical models! !
The amount of exhaust gas is generally calculated based on the amount of gas used
