Industrial Accident: Dual Fuel Boiler Explosion

Industrial Accident: a boiler fueled by both oil and natural gas exploded while being lighted after switching fuel sources. The burner management was incuded in an existing Distributed Control System DCS that controlled the oil gun purge, firebox purge, and ignition sequence. The DCS programming from a prior project was not properly modified to accomodate the particular requirements of this complex dual fuel system. The altered code affected the oil gun steam purge timing during repeated switchover attempts.
