THERMODYNAMIC AND ECONOMICALLY SOUND DESIGN OF FEEDHEATING EQUIPMENT.

Thermodynamic improvements, and often gains in output as well, can be achieved in the steam power generating process by means of additional heat transfer devices. This article examines drain coolers and drain pumps in conventional and nuclear plants, and also cross-connected desuperheaters in conventional power plants. In addition it considers separate drain coolers for the condensate from the reheater and the thermodynamic effects of the two-stage reheater in nuclear power stations.
