Abstract
An apparatus and process are provided for recovering and utilizing heat emanating from the shell of a thermal reactor in a sulfur recovery plant. Air is allowed to pass between the metal shell of a thermal reactor and an insulating jacket that partially encloses the shell. As the air exits through an opening at the top of the insulating jacket it is collected by a collection hood located above the thermal reactor. The collected air is then forced into the inlet of the thermal reactor where it is mixed with acid gas and thereby the heat emanating from the thermal reactor is recirculated to heat the reaction zone.
