METHOD AND A DEVICE FOR THE GENERATION OF STEAM IN STEAM POWER PLANTS, WHEREIN COLD CONDENSATE AND/OR COMBUSTION AIR IS PREHEATED BEFORE THE GENERATION OF STEAM

摘要

The invention relates to a device and a method for the generation of steam in steam power plants, wherein cold condensate and/or combustion air is preheated before the generation of steam, wherein part of the cold condensate, or of the combustion air, is preheated in a conventional manner by means of one or more preheaters, and part of the cold condensate, or of the combustion air, is preheated by means of geothermal energy.
