HP Section

	The High Pressure Section of the station was completed during World War II and comprised four boilers nos. 13, 14,15 and 16 and two turbo alternators nos. 7 and 8. The boilers were rated at 100,000 lbs/hr at 425 psi and the Turbo Alternators rated at 15,000 kw MCR each at 11,000 volts. Alternator 7 was directly switched at 11,000 volts and Alternator 8 switched at 33,000 volts via a generator transformer.

	Cooling water for the turbine condensers was potentially limited by the River Teign and Lemon flows so the construction included the famous single cooling tower that dominated the town for a little over thirty years. my recollection is that the MP turbines were integrated in this provision and the original MP (No 2) pump house used to both top up and provide cooling water.

	A further feature of this build was the need for high quality condensate for the boilers and steam cycle. An evaporator was installed in the turbine hall between generators 7 and 8 which was steam fed. Later in the station life as the running hours reduced a demineralisation plant was installed. This meant that boiler feed water levels in the condensate tanks could be maintained without the need to raise steam.

	At the far end of the turbine hall behind the cladding was the 11kv Metal clad switch room. During 1959 or 60 fire protection was added in the form of CO2 extinguishers - it was tested with station personnel inside the room who had to get out before being overcome! We did get out but were definitely woozy - procedures and Risk Assessment have moved on somewhat?
