How do multi-pass heating furnaces prevent flow deviation? What are the consequences of flow deviation?

Preventive measures mostly involve using control valves; the consequence of this is that the temperatures at various points at the furnace outlet are inconsistent, leading to uneven heating over time and coking of the furnace tubes.

Each channel is equipped with a flow meter and a thermometer; operation is based on temperature, as deviation in flow can easily lead to coking
