AES Maritza East 1 EOOD, an operator of a lignite coal powerplant located near Galabovo, Southern Bulgaria, is a part of The AES Corporation, a USA-based global energy company. The $1.4B 670-MW facility represents one of the single largest turnkey projects and foreign investments in Bulgaria to date, as well as one of the largest greenfield investments in Southeast Europe. It is the cleanest fossil fuel powerplant in Bulgaria, meeting World Bank environmental standards.
For many years, the AES Maritza site has been using a pipe conveyor belt for the transportation of the waste. However, after long use, the pipe conveyor belt has worn out, started requiring increasing maintenance costs and needed a more efficient and robust technology-based replacement. As a huge amount of waste is being transported on a regular basis from the plant to the waste disposal facility, there was also a need for equipment that would guarantee an undisrupted waste disposal process in order to ensure human and environmental safety.
At the end of September 2020, Metso Outotec crew successfully completed a month-long installation of a 9250m Metso Outotec conveyor belt in the pipe conveyor of AES Maritza. The delivered FLEXOPIPE conveyor belt is a 1500 ST1500 XP. With a belt width of 1500mm, the closed pipe belt with overlapped edges creates a diameter of 400mm, runs at a speed of 4.8m/sec and has a capacity of 1.400 tons/hour.
- Constantly increasing maintenance costs on the old belt
- Smooth, environment-safe and undisrupted waste disposal process
- Installation of a new 9250m FLEXOPIPE conveyor belt
- Implementation of the whole project, including delivery of the conveyor belt and vulcanization works
