This large stainless steel chemical process reactor is an ASME Pressure Vessel mounted into a floor with a fire seal. Below the floor, the vessel is surrounded by a protective shroud, to insulate the direct firing natural gas heating system on the shell and bottom head of the vessel. The gas burner system was designed and supplied by a third party, and the package was shipped as a complete system and installed in Ontario, Canada for a major chemical producer. Similar applications of gas heating have been installed in other reactors and auto claves through the years.
