Porter firefighters returned to the Unit 10 turbine at NIPSCO’s Bailly
Generating Station on Monday after workers there smelled smoke, two days
after hot oil from a leak in the turbine ignited insulation at the unit.
CFD Capt. Rudy
Jimenez told the Chesterton Tribune today that, at 8:47 a.m. Monday,
a turbine crew was cleaning up after the fire early Saturday morning when
they smelled smoke and called 911. Responding firefighters subsequently
found insulation burning and used a dry-chemical extinguisher to douse the
turbine was taken off line after firefighters cleared the scene at 1:22 a.m.
Saturday, Jimenez said, it’s believed that “the unit was still hot and
circulating oil during the shut-down process,” and that at some point
leaking oil started the insulation smoldering again.
Jimenez did say
that, before clearing the scene on Saturday, firefighters used a thermal
imaging camera to confirm that the fire had been extinguished. “We checked
with the thermal imaging camera. We know the heat signatures. There was
nothing when we cleared on Saturday.”
the fire on Monday, Jimenez noted, firefighters performed more overhaul of
the turbine’s insulation. The CFD and PFD cleared the scene at 9:45 a.m.
Also responding to the scene: the Burns Harbor FD.
essentially duplicated a fire at Unit 10 on April 4, when the heat generated
by starting up the turbine ignited a small oil leak. The CFD and PFD
responded to that fire as well.
