Use CFD modeling to improve burner design and operation

Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature.

Chen, Z., Becht

Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature. They are the major energy-consuming components in a process plant,1 and their operations often can be optimized to reduce energy consumption and improve efficiency. Computational fluid dynamics (CFD) modeling can be used as an efficient and low-cost tool to improve the design and operation of new burners for process heaters. Many factors affect the performance of heater burners in a refinery. In addition to the burner design, the operating conditions of the burner [e.g., burner hardware settings, burner stoichiometry and excess oxygen (O2)
