In a 250 MW thermal power station, 13,000 litres of lubricating oil caught fire upon contact with a pipeline transporting superheated steam. The smoke covered the control room. A flash was produced with the oil vapours accumulated below the roof that caused considerable damages. The high pressure oil caused vibrations during the pumping of the inlet valves of the turbine driven feed pump. These vibrations were transmitted to the copper low pressure tubes (diameter 22 cm) carrying lubricating oil. The rupture of a solder was the main reason behind the accident. The oil stream projected droplets that caught fire at the various local hot spots of the pipe resulting in an upward oriented vertical blowpipe flame fuelled at 250 to 300 l/min for 45 min, operating time of the pump. The repairs lasted for over a month. The damage was assessed at 10 MF. Corrective measures were implemented during operations to avoid another accident.
