Mong Duong Thermal Power Company solves the problem of ash and slag consumption

Because of the different color of the slag, it used to be difficult to find a market for the ash and slag of Mong Duong Thermal Power Company. And now, 100% of the company's bottom slag and fly ash have been marketable.

Which solution has been taken?

At the end of 2018, after the Ministry of Science and Technology issued Decision No. 2847/QD-BKHCN dated 28 September 2018 on the publication of the National Standard TCVN 12249:2018 for using coal-fired thermal power ash and slag as leveling material, along with the policies and directions of the Government, ministries and local authorities, MongDuong Thermal Power Company has been closely coordinating with the competent authorities to test and analyze ash and slag components. As a result, the plant's ash and slag all meet the currently prescribed standards.

Right after the plant's ash and slag were certified as qualified and eligible, the company has actively been seeking partners to promote the ash and slag consumption. Since the beginning of 2019, 100% of the company's bottom slag and fly ash have been consumed, of which 50% have been supplied to purchasers for being reused as building material additives or making unburnt bricks; the remaining 50% have been transported to Cam Phan city and neighboring provinces to be used as leveling materials.

In addition, to promote the consumption of ash and slag and keep the environmental hygiene during transportation, the company has implemented a solution to export ash and slag by waterway through the existing internal port infrastructure. When the port comes in stable operation, its loading and unloading capacity will be 2,000 tons of ash and slag per day, reducing transportation and storage costs for the company and minimizing environmental impacts.

Along with that, the company has been studying solutions to install roller conveyors to transport ash and slag from collection silos to the ash and slag loading port, contributing to reducing costs related to road transport as well as minimizing factors affecting the production environment, giving local people more secure with the management of electricity generation environment of Mong Duong Thermal Power Company.
