The two stacks of the simple cycle Gas Turbines of Siemens, Type V94.3 |
The existing power plant consists of two blocks, each equipped with one gas turbine of Siemens, Type V94.3 with 150 MW nominal output. The gas turbines are running on natural gas as the primary fuel and on oil as the standby fuel. The plant supplies its electric power to the EVN grid.
In the framework of this Add-On project, the existing 300 MW gas turbines plant should be extended from a simple cycle plant into a 460 MW combined cycle power plant. Each gas turbine should be connected to the corresponding heat recovery steam generator and the steam fed into one common 160 MW steam turbine.
The electrical efficiency of the combined cycle power plant achieves approx. 52%.
The Consultant Services to be provided are:
- Review and revision of all tender documents
- Clarification and evaluation of bids
- Contract negotiation with successful bidder
- Project management and technical services
- Supervision of construction and commissioning
- Shop and site inspection and expediting
- Reporting and documentation
- Training and know how transfer
The construction work for the project will start at the end of 2003.
The start up of the power plant operation in combined cycle mode is scheduled to be in Nov 2005.

Na Duong Coal-Fired Thermal Power Plant, 2 x 50 MW
Client: Vietnam National Coal Corporation (VINACOAL) (January 2004)
The Consultancy Services for the Vietnam National Coal Corporation for its Na Duong Thermal Power Plant Project was awarded to Colenco Power Engineering Ltd.
The Power Plant is located near the Na Duong Coal Mine in the Lang Son Province about 200 km north-east of Hanoi, near the Chinese border.

|
| Open-Cast Coal Mine |
|
The two CFB Boilers houses |
The coal, as main fuel, is of the lignite type with relatively high ash (20 to 40%) and sulphur (2.5 to 6.2%) content and a low calorific heating value (10.4 to 18.4 MJ/kg). The coal is conveyed by the open-cast method.
The two Boilers, designed for the Circulating Fluidized Bed (CFB) technology are most suitable to burn the local coal with a high combustion efficiency, at the same time keeping the NOx and SO2 emissions below the applicable emission standards.
The Power Plant is designed for base load operation. The generated steam of each boiler will be fed to a separate steam turbine. Each turbine will have a net output of approximately 50 MWel, i.e. the Na Duong Power Plant will have a total net output of about 100 MWel.
The steam turbine will be of the standard design, condensing, single-flow exhaust type. A cooling tower of the forced draft type for cooling of the condenser and auxiliary systems will be provided.
The power will be fed via the generator transformer to the 110-kV switchyard and from there to the grid of EVN (Electricity of Vietnam).

Cao Ngan Coal-Fired Thermal Power Plant, 2 x 50 MW
Client: Vietnam National Coal Corporation (VINACOAL) (January 2004)
Vietnam National Coal Corporation awarded Colenco Power Engineering Ltd the consultancy services for its Cao Ngan Thermal Power Plant Project.
Visualisation of the Cao Ngan Power Plant
The Cao Ngan Thermal Power Plant is currently being constructed at Quan Trieu ward, Thai Nguyen City approx. 80 km north of Hanoi in Vietnam. It is designed for base load operation. The Plant will use coal as main fuel which will be taken from the Khanh Hoa and Nui Hong coalfields.
The Cao Ngan Power Plant will have a total net output of about 2 x 50 MWel. The two boilers are designed for the Circulating Fluidized Bed (CFB) technology which is most suitable to burn the local coal with a high combustion efficiency, at the same time keeping the NOx and SO2 emissions below the applicable emission standards.
The required service and cooling water for the Plant shall be taken from the Cau River through a pipeline to the raw water settling tank. The required water quality will be achieved in a conventional Water Treatment Plant.
