Abstract
This paper examines some of the technical and operating problems which must be faced in the selection of equipment to supply steam to high-pressure turbine-generating equipment employing steam resuperheated to high temperatures in the low-pressure section. The costs of steam-generating equipment per kilowatt of turbine-generator capability for resuperheating cycles are compared with costs of equipment for cycles which do not employ resuperheating. The effects on equipment costs, of furnace-exit temperature limitations imposed by fuel quality and load range over which primary and resuperheated steam temperatures must remain constant, are examined in detail. Data are presented comparing present-day prices of steam-generating equipment per kilowatt of turbine-generator capability for several high-temperature and high-pressure resuperheating and nonresuperheating cycles usually employed in power stations.
