Infrared fire safety and detection system installed at Chinese hydro-electric power station
13 June 2007
The Longtan Hydropower Station, one of the world’s largest hydro-electric power stations, situated on the Hongshui River in the Guong-Xi province of China, will use 100 Fireray 100R reflective beam smoke detectors as part of the complete fire safety and detection system provided by Cooper Asia.
Due for completion in 2009 but already partially operational, the 216.5m high dam has had US$3.75 billion invested in its construction and will be capable of an estimated maximum annual production of 18.7 billion kWh of electricity. It is the world’s highest roller compacted concrete dam, and incorporates the world’s fastest ship lift.
The Fireray 100R reflective beam smoke detector from Fire Fighting Enterprises houses the transmitter and receiver in the same unit, with the infrared light being bounced back by a small prismatic plate on the opposite wall. This allows the coverage of a wide area by relatively few units, reducing the disruptions and costs of both installation and cabling.
As a part of the fire safety system, these devices will cover large areas which would otherwise have required the installation of numerous ‘point’ detectors – as many as 16 per unit – to safely monitor the 1500m2 that each 100R is effective over.
