Brimsdown Power Station was a
. The station had seven cooling towers which were visible from a wide area.History
The first station was brought into operation by the North Metropolitan Electric Power Supply Company between 1904 and 1907, before officially opening in 1907. It was used primarily to supply the local tramways. The station was extended between 1924 and 1955, supplying power to the wider area of Enfield and Essex.[1]
Brimsdown Power Station was the only known British example of the Loeffler boiler system. It was a system that enjoyed a brief vogue in the 1930s, mainly in Europe. It overcame metallurgical and feedwater quality problems but rapid advances rendered it unnecessary quite quickly.[2] The Parsons 25 MW turbo-alternator commissioned in 1928 was the first machine in the UK to generate direct at 33 kV.[3]
Coal was supplied by barge or by rail.
In 1948 Britain's electricity supply industry was nationalised under the
Technical Specification
In 1959 the A station had two Loeffler boilers, steam capacity of the boilers was 330,000 lb/hr (41.6 kg/s) which supplied one 20 MW and one 31 MW Metropolitan Vickers turbo-alternators.[4][5] The steam conditions at the turbine stop valve was 1900 psi (131 bar) and 499 °C. The overall thermal efficiency of the A station in 1963-64 was 20.16 per cent.[4]
In 1959 the B station had four Parsons 25 MW turbo-alternators and one Metropolitan Vickers 56.9 MW twin set.[5] By 1963-64 the B station had 1 × 60.27 MW and 1 × 60 MW generators.[4] The steam capacity of the associated boilers was 2,305,000 lb/hr (290.4 kg/s). Steam conditions at the 60.27 MW turbine stop valve was 315 / 900 psi (21.7 / 62.1 bar) and 360 / 399 / 482 °C. Steam conditions at the 60 MW turbine stop valve was 1900 psi (131 bar) and 499 °C. In 1963-64 the overall thermal efficiency of the B station was 23.17 per cent.[4]
There were 5 film cooling towers with a capacity of 6.6 million gallons per hour, and two natural draft reinforced concrete cooling towers each with a capacity of 1.56 million gallons per hour. Water was abstracted from the River Lea.[5]
Electricity output from Brimsdown A and B power stations during their final years of operation was as follows.[4][6][7]
