A non-contact, infrared temperature measurement system, from Land Infrared, is helping to maximise the efficiency of Rye Power Station, near Hoddesdon, Herts.

The combined cycle gas turbine stations produces 700 megawatts of electricity. Three gas turbines burn natural gas in compressed air at 110-1,450srC, producing combustion gases to drive a 150MW generator.

Greater thermal efficiency can be achieved by using air-cooled turbine blades, but, because they are exposed to temperatures well above their operating limit, they rely upon an unimpeded flow of cooling air for thermal protection. It is therefore vital to monitor the temperature of the blades.

Infrared temperature measurement can also be used to improve the turbine firing rate, to detect blocked cooling channels, as well as preventing blade failure.
