Scottish & Southern Slough Power Station

This was until recently the private power station for Slough Trading Estate. This has been supplying heat and power to the estate since 1920. Originally coal fired, it has now gone over to predominantly biomass (wood) firing. There is also some natural gas and heavy fuel oil in the mix. The modern building on the right houses a wood briquetting plant. The tall building in front of the chimney houses one of the modern wood fired plants including a Peter Brotherhood steam turbine with roof mounted air-cooled condenser. The tall building beyond the chimney houses two fluidised bed boilers that originally burnt coal but now burn wood. Older buildings house further older boilers (gas fired) and the four remaining steam turbines (one Siemens, one Brotherhood and two by C A Parsons). There is also a John Brown gas turbine of 23 MW. The two cooling towers are also part of the plant, although there is also pass-out steam at 14 bar to other users on the estate. It was recently acquired by Scottish & Southern, presumably to improve their CO2 emissions as it is biomass fired.
