​​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.

Pressure Parts ASTM Specifications

Key Pressure Components Involved​​:

1. ​​Tubes/Tube Bundles​​: Exposed to high temperatures and pressures, these carry the process fluid through the radiant and convection sections.
2. ​​Tube Sheets/Headers​​: Thick metal plates or assemblies that secure tube ends, maintaining structural integrity under pressure.
3. ​​Coil Piping/Return Bends​​: Connect tube sections, designed to withstand thermal expansion and operational stress.
4. ​​Burner Assemblies​​: Fuel injection systems operating under controlled pressure for efficient combustion.
5. ​​Firebox/Combustion Chamber​​: Built to handle high-pressure combustion gases and radiant heat.
6. ​​Stack/Damper​​: Manages flue gas exhaust pressure and flow.
