Modern Tendencies in Steam Power Plants

Abstract

This paper describes the present status of modern steam power plants, especially with regard to the use of high-pressure and high-temperature steam, the improvement of the thermal efficiency by means of the reheating and the regenerative cycles.
Remarkable developments in boilers, turbines, condensers and mechanical stokers, the application of pulverized-coal burning, the change in shape and size of furnaces, the problem of air-preheaters versus economizers, improvement of mechanical stokers and the use of mercury-vapour cycle are discussed.
The auther wishes that home-made boilers or turbines, as well as other machineries, shall be widely used in Japan, by pointing out the prghorsent conditions of most of the steam power plants in this country.
