Inpetroleumreningandpetrochemicalplantsred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reningprocessbutratheroftenormoreprocesses,thismeansthatyouhavethat
manyredheaters,too(locatedatthearrowsinthediagramabove).
Inadditiontotheredheaters,therewillalsobeanumberofboilers.Thuscombustion
monitoring (or control) is a vital element.
