At opening the station was equipped with three Babcock and Wilcox boilers feeding steam to three Brush Electrical Engineering Co. sets of 75 kW each. Power was distributed at 1100 Volts to three remote substations where it was reduced using motor generating sets. In 1923 the steam generating plant at Barrow comprised: • Coal-fired boilers generating up to 112,000 lb/h (14.11 kg/s) of steam, these supplied steam to: • Generators • 3 × 75 kW
reciprocating engines driving
direct current (DC) generators • 2 × 150 kW reciprocating engines driving DC generators • 2 × 250 kW reciprocating engines driving DC generators • 1 × 1,000 kW steam
turbo-alternator • 1 × 2,000 kW steam turbo-alternator • 1 × 3,000 kW steam turbo-alternator These machines had a total generating capacity of 8,000 kW of
alternating current and 1,025 kW direct current. A variety of electricity supplies were available to consumers: • 3-phase, 50 Hz AC at 6,300 Volts, 380 V and 220 V. • Direct current at 500, 440 and 220 Volts. Coal could be delivered to the station from a siding off the railway just south of Barrow-in-Furness railway station.
New plant, 1950s New plant was commissioned over the operational life of the station. In the late 1950s the plant at the station comprised: • Boilers: • 3 × Stirling boilers with chain grate stokers, all with a final steam pressure of 200 psi (13.8 bar), and with capacities of : • 30,000 lb/h (3.78 kg/s) at 650 °F (343 °C); • 55,000 lb/h (6.93 kg/s) at 700 °F (371 °C); • 90,000 lb/h (11.3 kg/s) at 700 °F (371 °C) The boilers had a total evaporative capacity of 175,000 lb/h (22.0 kg/s), and supplied steam to: • Turbo-alternators: • 1 ×
Metropolitan Vickers 10 MW turbo-alternator, with Vickers condensing plant • 1 × Metropolitan Vickers 7 MW turbo-alternator, with Vickers condensing plant • 1 × Howden-Siemens 1 MW turbo-alternator, with Willans and Robinson condensing plant • 1 × Howden-Siemens 3 MW turbo-alternator, with Worthington Simpsons condensing plant • 1 ×
British Thomson-Houston 2 MW turbo-alternator, with Cole, Merchant and Morley's surface condensing plant The total installed generating capacity was 23 MW, with an output capacity of 14 MW. Condenser cooling water was cooled in three wooden
cooling towers with a combined capacity of 0.45 million gallons per hour (0.57 m3/s) plus one concrete cooling tower with a capacity of 1.0 million gallons per hour (1.26 m3/s). The corporation also operated Coniston water turbine generating station at Coniston. This comprised 2 × 150 kW Gilkes-Metropolitan-Vickers water turbo-alternator sets. These generated current at 450 Volts. ==Operations==
