Against the backdrop of the iterative upgrading of global energy equipment and the accelerated advancement of overseas power engineering construction, DaTongLongYuan continues to deepen its presence in the Indonesian market, building overseas benchmark projects with core technologies and full-process high-quality services. Undertaken by DaTongLongYuan, the MPS89N coal mill upgrading and renovation project for the 600MW No.7 coal-fired unit of PT PLN INDONESIA POWER UBP SURALAYA under Indonesia's state-owned power company has been successfully completed and put into operation, providing solid support for the safe and stable operation of Indonesia’s power grid.

Precise Breakthrough & Efficient Performance
Suralaya Power Plant is a core large-scale coal-fired power station of Indonesia's state-owned power company, occupying a pivotal position in the power supply guarantee system of the Java power grid. This renovation involves the overall upgrading of two medium-speed coal mills (7C and 7E) of the No.7 unit, covering core systems including the coal mill body, drive motor, reducer and dynamic separator, featuring high technical requirements and a tight construction schedule.
Faced with multiple challenges such as complex on-site overseas environment, stringent operation standards and numerous coordination links, the project team of DaTongLongYuan rose to difficulties and worked around the clock. With rigorous management and professional execution, the team efficiently completed the whole process including equipment installation, system joint commissioning and performance optimization. Strictly adhering to safety bottom lines, quality standards and construction schedule nodes, the project was put into operation safely, with high quality and on schedule.
The two coal mills successfully passed the full-load performance test at one go, operating stably and reliably. Key parameters such as pulverized coal fineness, vibration and temperature all met the standards in full. The overall output and performance indicators of the unit fully satisfied and exceeded contractual requirements, earning high recognition and praise from the owner for the project quality and service level.

Empowerment by Technology & Value Upgrading
Centering on the core goals of improving the output of the pulverizing system and ensuring operational stability and economy, the MPS89N coal mill upgrading and renovation project has significantly optimized pulverized coal quality, reduced equipment energy consumption and failure rate, and laid a solid technical foundation for the long-term safe, efficient, full-load and stable power generation of the No.7 unit.
The successful commissioning of the project fully demonstrates DaTongLongYuan’s technical strength in power equipment upgrading and coal-fired unit technical renovation, and comprehensively verifies the company’s full-process delivery and service capabilities for overseas projects.

Deepen Overseas Layout & Seek Win-Win Future
The successful cooperation with Indonesia's state-owned power company has further consolidated the long-term strategic partnership of mutual trust between both sides, and continuously enhanced the brand influence of DaTongLongYuan in Indonesia and the Southeast Asian energy market.
In the future, adhering to craftsmanship spirit and technological innovation, the company will further explore the global energy market with robust solutions and high-quality engineering services, forge more overseas benchmark projects, and contribute professional strength to the high-quality development of the global power industry.
