Working conditions of petrochemical heating furnace
【Summary】Using hydrocarbons as raw materials to produce synthetic ammonia feed gas and hydrogen by steam reforming has a specific position in the synthetic ammonia, oil refining, petrochemical, metallurgical and other industrial sectors. The hydrogen production furnace of the refinery, the hydrogen production reformer of the methanol plant and the first-stage reformer of the synthetic ammonia plant are all petrochemical heating furnaces.

The hydrogen production furnace of the refinery, the hydrogen production reformer of the methanol plant and the first-stage reformer of the synthetic ammonia plant are all petrochemical heating furnaces.
The working conditions of petrochemical heating furnaces are relatively harsh, and high temperature resistant alloy materials containing high nickel and chromium are used. Therefore, the furnace design requires reasonable use of furnace tubes and minimizes the requirements for furnace tubes to prevent local overheating and make the circumference And the axial temperature distribution is uniform. Note that the furnace type, raw materials, catalysts and operating conditions selected in the design are a whole.
