Investigations into a boiler blast that killed 32 and left scores injured on Wednesday at state-run NTPC's power plant in Raebareli in Uttar Pradesh have revealed that engineers were aware of a problem in the boiler unit commissioned just months ago and were working to fix it. In a statement, NTPC (National Thermal Power Corporation) officials have said that "extremely high pressure" because of ash within the boiler furnace caused it to leak, producing a disaster.
