Hydrogen mixing in front of the furnace prevents coking in the heating furnace; it also increases the flow rate, aiding in the vaporization of oil and gas and preventing uneven flow within the furnace tubes. The vaporization capacity resulting from hydrogen mixing in front of the furnace seems to be about 300 times higher, I think, though I’ve forgotten the exact figure
Usually, heavy oil is mixed with hydrogen after the furnace, while light oil is mixed before the furnace, in order to prevent coking and blockages in the furnace tubes; there were indeed such posts on forums in the past
