Fired Heater Specifications Beyond API 560

Fired Heaters are one of the major equipment in the refining process. They must be specified correctly to meet efficiency, emissions, and reliability requirements. Fired heaters know-how used to be the oil majors in the past, but for the last 35 years, it has been passed on to the industry in the form of API-560 Industry Specification. It is an excellent document and currently in the 5th edition. API560 basically covers the mechanical design and fabrication of fired heaters and leaves the heater vendors' process design. This design gap makes the heater procurement process very difficult as the focus is on the low cost. Furnace Improvements wants to highlight the gaps in API560 and how you can ensure a reliable and efficient fired heater for your next project.
