Petroleum Refining And Petrochemical Fired Heaters - YOKOGAWA EXAxt ZR22G Technical Information

4.4 Petroleum Refining and Petrochemical
Fired Heaters
In petroleum refining and petrochemical plants fired heaters are so numerous that you could
almost say that there is one in almost every process. Also, since a site consists not of just a single
petroleum refining process but rather of ten or more processes, this means that you have that
many fired heaters, too (located at the arrows in the diagram above).
In addition to the fired heaters, there will also be a number of boilers. Thus combustion
monitoring (or control) is a vital element.
