US Patent 7478524 Coal fired power generation plant

A power generation plant includes a conventional steam turbo train, a high temperature turbo train, and a coal fired boiler (1) with a fluidized bed combustor. The high temperature turbo train is particularly arranged vertically and in parallel with the coal fired boiler (1) and separately from the conventional turbo train. Transfer flow lines (4, 5, 6) are run from the boiler (1) to the high temperature turbines over minimal lengths. The arrangement of the two turbo trains separately from one another and the vertical arrangement of the high temperature turbo train are advantageous in terms of plant efficiency and fabrication and maintenance thereof.
