Check out a time-lapse of the post-weld heat treatment process on a large pressure vessel on-site at customer location. The video walks you through the initial set up, cook and strip out of PWHT on an 85' X 11' vessel.
The process here is using ceramic fiberglass insulation along with high-velocity gas combustion equipment to complete PWHT in accordance with ASME Sec, VIII Div. 1.
