Brown, D

The directions the development of turbomachinery and power generation systems may take are reviewed and the changes in technology that will be required are considered. Three potential methods of utilizing coal in future large-scale power generation are considered, i.e., direct combustion of coal in the primary air circuit of an open-cycle gas turbine, with recovery of the exhaust heat from the gas-turbine cycle in a steam-bottoming cycle (production of steam in the combustor is considered as a variant to this cycle); provision of a clean fuel derived from coal, either in an integrated coal-processing plant or in a centrally located coal-processing plant, the fuel then being burned in an open-cycle gas turbine with a steam-bottoming cycle; and a closed-cycle gas turbine, probably with helium as a working fluid.
