FCI Sandstone - Site Visit Replace Boiler Controls Project Pictures.pdf

This is a set of technical photographs and documentation showing three Superior Boiler Works high-pressure boilers with Weishaupt burner controls installed at FCI Sandstone Prison. The images show the boiler system specifications, control panels, and wiring diagrams from a 2004 installation. The boilers are Superior model X6-X-3000 with 3,017 sq ft heating surface, 150 PSI design pressure, and 20,700 lbs/hr steam capacity. The burners are Weishaupt model RGL70/1-A ZM-NR dual fuel (natural gas/oil) burners with 3,413-27,987 MBTUH capacity range.

The documentation includes detailed field wiring diagrams, panel layouts, and control system schematics for the boiler control system. The control panels feature Danfoss VLT 4000 VT drives and Weishaupt digital controls with status displays showing operating parameters like load percentage and flame signal strength. Warning signs indicate these are confined space installations requiring permits for entry. This appears to be the existing boiler control system that will be replaced under the referenced contract opportunity for new Siemens LMV52 or equivalent controls with 12-inch touch screen interface.
