- Operation date: 1998 (after revamping)
- Project type: Instrumentation & Control (I&C) revamping
- Plant configuration:
Boilers: Barnual Boiler Factory, Russia
Steam Turbines: Leningrad/Sankt Peterburg/Turbine Factory
- Overview: The plant was jointly constructed by the Soviet Union (USSR) and Mongolia, and entered operation in 1983. With the dissolution of the USSR in 1991, the supply of spare parts was stopped. The Japanese government extended a soft loan in two phases to provide materials and engineers. As part of the work in phase one, which commenced in 1996, Yokogawa received an order to replace the control systems, field sensors and control valves for boilers number 1 through 4.

(Solutions/benefits)
- Completed overall I&C replacement in spite of difficulties:
The plant site was very remote with poor transport and infrastructure, and an extremely harsh environment in winter. In addition, the documentation for the original construction work was almost non-existent. In spite of these difficult situations, Yokogawa assumed overall responsibility for the I&C replacement and worked in close cooperation with the customers to carry out system design/engineering, configuration, project management, commissioning services, and operator training. This work covered the customers' needs over the whole project life cycle and was key to the project's success. The owner was satisfied with Yokogawa's commitment to the project meeting and often exceeding his expectations.

- Control scope:
Coordinated boiler and turbine control
Mill and burner management control
Balance of Plant

- System equipment:
Micro-XL
YS100 single-loop controllers
FA M3 PLC
Training simulator

(Replica simulator showcase)
A full scope, high fidelity training simulator was supplied by Yokogawa. The simulator is used for operation and for maintenance training to prevent plant outages.
