The operating conditions for a pure oxygen burner for partial oxidation (POX) are extreme due to the extremely high temperature needed to achieve a high conversion of natural gas to CO and H2: the reformed gas temperature at the reactor outlet is maintained in the range of 1,200-1,400°C, with the maximum flame temperature around 2,800-2,900°C.

Casale POx burners are designed to overcome the difficulties connected with partial oxidation of natural gas with pure oxygen, chiefly to eliminate carbon soot formation for every load condition, even with heavy natural gas.

Accurate mechanical design together with the design of the water-cooling system is crucial for a long and safe operating life for a burner operating in such harsh conditions: the Casale burner cooling water system is designed to achieve the maximum cooling efficiency where needed in both the burner body and the oxygen lance.
