Smokin' power plant

From NBC:

Firefighters are looking into what caused heavy black smoke to billow from a smokestack at a power plant near the East River in Queens Monday.

Firefighters were called to TransCanada's Ravenswood power plant at Vernon Boulevard and 37th Avenue in Long Island City about 4:30 p.m. Neighbors from both the west side of Queens and the east side of Manhattan reported seeing thick smoke coming from one of the four red and white smokestacks.

According to the energy company, a boiler combustion fan lost power, causing the inside of the smoke stack to overheat and produce black smoke.
