NEWS IN BRIEF Siwertell ship unloader meets Quezon’s doubled power demands A new Siwertell ST 790 D-type ship unloader now serves Quezon Power Ltd Co’s newly built coal-fired San Buenaventura power plant in Mauban, the Philippines. The 500 MW facility is the country’s first supercritical power station and is located next to an existing Quezon power plant. Since coming online, the operator’s energy output has doubled, requiring an equivalent doubling of coal intake to around three million metric tons a year. These needs are now met with two rail-traveling Siwertell ST 790 D-type unloaders, which share the same jetty, rails and belt conveyors.

Siwertell screw-type ship unloaders are one of most efficient and environment-friendly types of unloaders on the market. They deliver totally enclosed dry bulk material handling, eliminating spillage and dust emissions, and also ensure 4
