Majuba coal silo recovery achieves completion

On Monday, South African state-owned power utility, Eskom, announced that the construction of a permanent coal-handling solution for the Majuba power station has been completed.

This includes the rebuilding of Silo 20, the reinforcement of Silos 10 and 30, lift shaft, two piers and the coal conveyor system.

Eskom’s group executive for group capital, Abram Masango, said: “We commend the various teams for diligently working round the clock to ensure that work on the damaged silo was completed seamlessly and within the set timeframes.

“It is no wonder that the project’s interim solution won the Eskom Group Capital Best Project of the Year 2015 award. The completion of the project will go a long way in ensuring a reliable electricity supply to enable economic growth.”

Majuba structural failure

In November 2014, the Majuba coal-fired plant suffered damage to one of its silos which cracked and collapsed, holding 10,000 tonnes of coal resources. Read more…

Eskom noted that due to the structural failure of the coal silo and the associated conveying infrastructure, no coal supply to any of the station’s three silos was possible.

To enable coal supply to the station, an immediate solution was executed within five days after the collapse of the silo.

The immediate solution entailed installation of mobile feeders on Silos 10 and 30 boiler incline to make it possible to supply coal to the units.

The solution ensured that at least four out of the six boiler incline conveyors could supply coal to the units, the parastatal explained. Read more…

“To ensure coal supply to all six units at the power station, an interim solution was put in place from 1 March 2015 that involved the construction of a conveyor system that bypassed the coal silos and provided a reliable coal supply to all six units,” Eskom said.

Adding that: “Construction work for the permanent coal-handling solution commenced at the beginning of February 2016 and was concluded by end-December 2016.

“The scope for the permanent coal handling solution included the rebuilding of Silo 20, the reinforcement of Silos 10 and 30, lift shaft, two piers and the coal conveyor system.”
