Zusammenfassung:The invention relates to a method for generating energy by means of thermal cycles with high pressure and moderate temperature steam, which allows improving the energy and operational efficiency of the conversion of heat energy into mechanical or electrical energy by means of thermal cycles in which the temperature of the steam is limited to moderate values in its generation, comprising the following steps: a) generating steam at a pressure above 65 bar and a moderate temperature below 400°C, b) expanding said steam in a steam turbine, steam of an intermediate pressure, comprised between 10-40 bar, with a moderate moisture, below 15%, being obtained c) drying said steam by means of a moisture separator and reheating said steam, d) expanding said steam in the turbine, and e) heating boiler water used to generate the steam by means of a plurality of steam extractions from the turbine, in order to exchange heat with said boiler water. Procedimiento para generar energía mediante ciclos térmicos con vapor de presión elevada y temperatura moderada, que permite mejorar la eficiencia energética y operativa de la conversión de energía calorífica en energía mecánica o eléctrica, mediante ciclos térmicos en los que la temperatura del vapor está limitada a valores moderados en su generación, comprendiendo las siguientes etapas: a) generar vapor a presión superior a 65 bar, y temperatura moderada, inferior a 400°C, b) expandir dicho vapor en una turbina de vapor, obteniéndose vapor de presión intermedia, comprendida entre 10-40 bar, con humedad moderada, inferior al 15%, c) secar dicho vapor mediante un separador de humedad, y recalentar dicho vapor, d) expandir dicho vapor en la turbina, y e) calentar agua de calderas utilizada para generar el vapor, mediante una pluralidad de extracciones de vapor de la turbina, para intercambiar calor con dicho agua de calderas.
