What tubes run vertically in a furnace?

Explanation:
Radiant tubes are designed for heat transfer from the flame by radiation, so they sit in the furnace’s radiant section where the heat is hottest. Placing these tubes vertically puts their surfaces directly in the intense flame radiation, which lets them absorb heat most efficiently and transfer it to the surrounding water or steam. This orientation also helps keep heat concentrated where it’s needed and makes maintenance and inspection easier.
