Abstract
Steam power stations are one of the biggest users of water and the increasingly heavy demand for water, for all purposes, throughout the world has caused serious studies to be made of methods of providing a cooling facility for steam turbines independent of a water supply.
The studies revealed that a system devised by Professor Heller provided the most economic and practical solution for large steam turbines. It uses the atmosphere as a heat sink for the turbine exhaust heat by a combination of jet condenser, closed water circuit, heat exchangers cooled by air and a cooling tower. Although there is a water circuit to be filled initially, no further water is required.
The first application of the system—the dry cooling tower system—to a large turbine was designed and built by the English Electric Company Ltd for the C.E.G.B. at their Rugeley Power Station and this paper describes the project and its behaviour in service.
