Issues with the reformation four-in-one furnace
Thread Content
In the reformation four-in-one furnace, the second furnace has a higher heating load and consumes more fuel gas. I would like to ask how the oxygen content in it is controlled – will there be an excess of oxygen?
We use manual dampers for control; generally, when the temperature drop in the reforming reaction is not significant, the operator monitors the DCS screen while making adjustments to the dampers manually. Once the settings are stabilized, they can remain effective for a long time, and fine adjustments can be made using baffles to regulate the negative pressure
Reduce the negative pressure a bit; this will minimize the loss of heat carried away. As a result, the gas flow rate into the furnace will decrease, and everything else will correspondingly drop as well. Typically, negative pressure is adjusted using dampers in the flue at the bottom of the furnace and dampers at the top of the tower.
But the four-in-one furnace is a single unit; if the negative pressure is too low, it will affect the other three furnaces, right?
So what are the temperatures of your F202 before and after heating?
