Valero Energy Corp's 245,000 barrel per day (bpd) Texas City, Texas, refinery continued to operate after a boiler failure that killed one worker and injured two others, the company said on Friday night.                                           

Local media reports called the incident an explosion but Valero spokesman Bill Day said the company could only confirm that a boiler failed at the refinery.                                           

The extent of the damage and the cause of the failure are under investigation, Day said.
