Littlebrook D Power Station – Turbines

Littlebrook D Power Station Turbine Hall

Littlebrook comprised three 660MW turbo-generator sets manufactured by GEC. The turbines are four cylinder reheat machines running at 3,000 rev/min. Each turbine has a single-flow high pressure (HP) cylinder, a double-flow intermediate pressure (IP) cylinder and two double-flow low pressure (LP) cylinders. Unit 3 had been dismantled quite some time before the closure of the station.

The turbine output was increased to 685 MW during commissioning with practically no additional engineering works required which is testament to the robust design standards rigorously upheld by the CEGB.
