One layer of catalyst with four temperature points, one of which has a large temperature difference
Thread Content
There is one catalyst layer with four temperature points, and one of these points exhibits a large temperature difference. When the gas concentration is high, the temperature at this point can differ by nearly 30°C compared to the other three points (with a normal thermometer). What are some good ways to address this issue? Reduce this temperature difference at the catalyst site? (This point is far from the exhaust outlet) The SO2 smoke enters from the top of the first floor and then exits from the side.
Is this point higher or lower than the others? What are the changes under high and low loads?
Where is this dot located? Is there any bias current?
Top intake is prone to flow deviation
It’s a flow deviation; is there a good way to address the air flow distribution?
