ASME Sec I & API Std 560 Fired Heater for Delayed Coking Heaters in High-Sulfur Crude Processing
A fired heater, also known as a process heater or furnace, is a critical industrial equipment used to heat process fluids (e.g., hydrocarbons, gases, or chemicals) to specific temperatures in refineries, petrochemical plants, and other processing facilities. It operates by combusting fuel (e.g., gas, oil) in a firebox, generating heat that transfers to fluid-carrying tubes via radiation and convection.
